Hu Yong of Zhejiang Normal University and Lou Xiongwen of Nanyang University of science and technology published academic achievements on the top international chemical journal German Applied Chemistry

Recently, Professor Hu Yong, a leader in science and technology innovation of Zhejiang ten thousand talents program and a young and middle-aged expert with outstanding contributions from Zhejiang Province, and Professor Lou Xiongwen, a professor of Nanyang University of technology in Singapore, jointly published the research paper "construction of COO / co-cu-s hierarchical tubular" on the international top academic journal of chemistry, angew Chem Int ed Heterostructures for Hybrid Supercapacitors”（DOI: 10.1002/anie.201907516）。 The first author is Lu Wen, a 2017 graduate student of Zhejiang Normal University, and Zhejiang Normal University is the first unit With the increasing demand for energy applications, users put forward more requirements for the next generation of advanced energy storage devices, which are mobile and portable In addition to energy density, power density, cycle life, charging speed, reliability, safety, environmental protection, low cost and other factors have also become important considerations As a new type of energy storage device with environmental protection and excellent performance, electrochemical supercapacitor has attracted wide attention in the field of energy Hu Yong's group prepared the COO / co-cu-s layered tubular heterostructure composed of nanoneedles by an effective multi-step method Its unique layered hollow structure can expand the surface area, accelerate the transport of ions and electrons, and adapt to the volume expansion during the cycle In addition, the construction of heterostructures will enhance the internal electric field to regulate the electronic structure These characteristics of multilevel hollow heterostructure are helpful to improve the electrochemical performance and stability of electrode materials for supercapacitors The COO / co-cu-s multi-level tubular heterostructure has excellent electrochemical energy storage performance due to its unique hollow structure and synergistic effect These excellent properties make the COO / co-cu-s multi-level tubular heterostructure show a broad prospect in energy storage application system (source: angelw Chem Int ed.) was supported by the National Natural Science Foundation of China and the "ten thousand talents plan" science and technology innovation leading talent program of Zhejiang Province.
