    Recently, Professor Wang Haihui from the school of chemistry and chemical engineering of South China University of technology has developed a new electrochemical method for rapid preparation of zif-8 membrane The ultra-thin membrane prepared in more than ten minutes has a high separation selectivity of propylene / propane of more than 300, showing the highest separation selectivity of propylene and propane so far Relevant achievements were published in the top international journal science advances (DOI: 10.1126 / sciadv.aau1393) under the title of "parallel membrane: current driven synthesis of a metal organizational framework with sharp propene / propane separation" The corresponding author of the paper is Professor Wang Haihui, the co first author is Zhou Sheng, researcher Wei Yanying and Associate Professor Li Libo, the first unit of the paper is South China University of technology, and Professor J ü rgen Caro of Hanover university is the collaborator of the paper It is very important to separate propylene and propane in industry Because the boiling points of the two components are very close, the energy consumption of the traditional distillation method is quite high In this study, a method of electrochemical preparation of zif-8 film was proposed The rapid growth of zif-8 film on porous substrate at room temperature was realized for the first time by applying a milliampere level of small current, which took only a few minutes, the preparation process was very simple and fast, and had a good application prospect In the process of one-step electrosynthesis, this work solved many complex problems such as flexibility, grain boundary defects, film thickness control of zif-8 material, and brought new ideas for the development of membrane separation technology In recent years, Professor Wang Haihui's team has carried out a series of innovative research work on the application of new inorganic membrane in gas separation and water treatment, including: through the design of highly ordered two-dimensional mxene membrane pore structure, making it break through the limit of permeability selectivity trade off, obtaining excellent H 2 / Co 2 separation performance; preparing C 3N 4 with "self-supporting" structure Membrane, in order to enhance its stability; through electrochemical means, develop new strategies for the preparation of a series of MOF membranes, and optimize their growth orientation (NAT Commun 2018, 9, 155; angelw Chem Int ed 2017, 56, 1825; angelw Chem Int ed 2017, 56, 8974; chem Mater., 2017, 29, 7103) Relevant papers were selected in the first cover of ESI high cited papers and angelw Chem Int ed respectively The research work has received extensive international attention, and has been reported as highlights by more than 20 domestic and foreign media and journals, including EurekAlert under AAAs, nanowerk, advanced science news, chemistry views and Journal of physical chemistry under Wiley VCH.
