    Energy crisis and environmental pollution are two major problems that affect the sustainable development of human beings Using solar energy to convert CO2 into useful chemical fuel or chemical raw material is an ideal way to solve energy and environmental problems In the reported catalysts, the molecular complexes have the advantages of clear structure, which is helpful to analyze the structure-activity relationship and reveal the catalytic mechanism However, until now, how to improve the activity and selectivity of CO 2 reduction catalyst, as well as to clarify the catalytic mechanism, is still facing major challenges Recently, the research group of Professor Lu Tongbu, Institute of new energy materials and low carbon technology, Tianjin University of science and technology, has developed a strategy of CO 2 to CO conversion promoted by dual core metal co catalysis The results were published in angew Chem Int ed (DOI: 10.1002 / anie 201811010) A brief introduction to the research group of Professor of Lu Tong Bu, who is mainly engaged in the research of artificial photosynthesis catalyst in recent years, reported the first case of water oxidation molecular catalyst based on nickel metal (angelw Chem Int ed 2014, 53, 13042); all solution water photocatalyst based on MOF (Chem SCI 2016, 7, 1070); bifunctional electrocatalyst based on Ni 2p @ NiFe hydroxyl compound heterojunction (chem SCI 2018, 9, 1375); photocatalyst based on graphite phase carbon nitride @ graphene heterojunction (adv energy mater 2018, 8, 1702992); high efficiency electrocatalyst based on monoproton platinum (angel Chem Int ed 2018, 57, 9382 ), based on the macrocyclic binuclear cobalt (angel Chem Int ed 2017, 56, 738, cover paper; angel Chem Int ed doi: 10.1002/anie.201811010), proposed the concept of binuclear metal synergistic catalysis, and invited to write a review on coord Chem Rev 2018, 377, 225; coord Chem Rev 2019 , 378 , 237 )。
    Prof Lu Tong, Professor, doctoral supervisor In 1993, he graduated from the Department of chemistry of Lanzhou University and worked in the post doctoral mobile station of the Department of chemistry of Zhongshan University In 1995, he left the station to teach Transferred to Tianjin University of technology in 2016 Mainly engaged in the research of artificial photosynthesis catalyst He has successively presided over more than 20 research subjects, such as national key R & D plan (subject), National Science and technology major project, national fund for Distinguished Young Scholars project, national fund key project and general project, Guangdong Natural Science Fund team project, and "973" project subproject of the Ministry of Science and technology More than 220 papers have been published in core journals at home and abroad, including J am Chem SOC., angelw Chem Int ed., adv.energy mater., chem SCI., chem Commin., among which more than 200 papers are included in SCI 21 Chinese invention patents have been authorized He cited more than 5800 published papers, with an H index of 44 In 2005, he was selected into the "new century excellent talents support plan" of the Ministry of education, in 2006, he was awarded the national outstanding youth fund, and in 2009, he was selected as a special professor of "Pearl River scholars" in Guangdong Province In 2012, he received special allowance from the State Council In 2012, he won the second prize of National Natural Science (ranking No 5), and in 2013, he won the second prize of National Natural Science (ranking No 3) Selected as FRSC in 2014 At present, he is the director of China Crystal society, vice president of Tianjin Chemical Society, Chinese director of innovative subject introduction base of new energy materials, director of International Cooperation Joint Laboratory of Ministry of education of material microstructure, crystal engcomm, current green chemistry, current pharmaceutical design, Journal of crystallography, Editorial board member of Chinese Journal of inorganic analytical chemistry and co editor of Acta C Journal of international crystallography Cutting edge scientific research achievements: dual core metal catalysis promotes the transformation of CO2 into Co in recent years, with the support of the national key research and development plan of the Ministry of science and technology, the National Natural Science Foundation, and the academic innovation and intelligence introduction plan (111 plan) of the Ministry of education and other projects, the professor group of the Ministry of Lu Tong has developed a series of projects around visible light catalytic CO 2 reduction It is a highly efficient and selective non noble metal molecular complex catalyst in aqueous system First of all, they designed mononuclear CO (II), Cu (II) and Ni (II) complexes based on tripodal ligands It was found that [Ru (phen) 3] (PF 6) 2 was used as photosensitizer and triethanolamine was used as electron sacrificial agent Driven by visible light, these complexes showed good performance of photocatalytic reduction of CO 2 to CO (inorg Chem 2017, 56, 7307; chem EUR J 2018, 24, 4503; acscatal 2018, 8, 7612); secondly, they studied the coordination environment (chemsuschem 2018, 11, 1025), steric hindrance of ligands (chemcatchem 2018, 10, 3435), conjugation effect (ACS apply Energy lett 2018, 1, 2452), and confinement effect (chem Commin 2018, 54, 11308) It is found that the detailed design of ligands can greatly improve the ability of metal center to catalyze the reduction of CO 2 to Co based on the study of mononuclear complexes, considering that most of the catalytic systems in organisms are binuclear or polynuclear systems, they further designed the binuclear co complex based on aza ether, and found that it catalyzes CO 2 in visible light Reduction to CO has higher catalytic activity, with ton and TOF as high as 16896 and 0.47s-1, respectively, and the selectivity to CO as high as 98% The experimental and DFT theoretical calculation results show that the improvement of catalytic activity is attributed to the synergistic catalytic action between two CO (II), one CO (II) acts as the catalytic active center to combine and reduce CO 2, the other CO (II) As an auxiliary catalytic site, it can promote the departure of OH - in the intermediate o = c-oh, and reduce the activation energy of the fast-paced catalytic reaction (angelw Chem Int ed 2017, 56, 738) Figure 1 Structure and photocatalytic activity of binuclear and mononuclear catalysts (source: angelw Chem Int ed.) recently, under the guidance of the concept of synergetic catalysis, Professor Lu Tongbu's research group made important progress in the field of photocatalytic CO 2 reduction again, designed and constructed heteronuclear with stronger synergetic catalysis based on aza ether ligands The co Zn complex (Fig 1) and the co Zn Catalyst enhance the synergistic catalysis because Zn (II) has stronger binding force to Oh than CO (II), which is more conducive to the departure of OH - in the reaction intermediate o = c-oh, thus greatly promoting the reaction rate of CO 2 reduction to Co The results of these studies are supported by DFT theoretical calculations The research results were published on angelw.chem Int ed (DOI: 10.1002 / anie 201811010) under the title of "dinuclear metal collaborative catalyst boosts photochemical CO 2 - to-coconversion" The corresponding authors of this paper are Professor Zhong Di Chang and Professor Lu Tong bu Nowadays, people and scientific research have been paid more and more attention in the economic life China has ushered in the "node of science and technology explosion" Behind the progress of science and technology is the work of countless scientists In the field of chemistry, in the context of the pursuit of innovation driven, international cooperation has been strengthened, the influence of Returned Scholars in the field of R & D has become increasingly prominent, and many excellent research groups have emerged in China For this reason, CBG information adopts the 1 + X reporting mechanism CBG information, chembeangoapp, chembeango official microblog, CBG wechat subscription number and other platforms jointly launch the column of "people and scientific research", approach the domestic representative research group, pay attention to their research, listen to their stories, record their demeanor, and explore their scientific research spirit.
