Wenping Sun received his B.S. in 2008 and PhD in Materials Science in 2013 from University of Science and Technology of China (USTC). From September 2013 to May 2015, he worked as a postdoc fellow at Nanyang Technological University, Singapore. In June 2015, he moved to Institute for Superconducting and Electronic Materials at the University of Wollongong. His research is mainly focused on the development of efficient materials and nanostructures, and the fundamental understanding of electrochemical processes for energy storage and conversion devices, including electrocatalysis, batteries, solid oxide fuel cells, and supercapacitors. His current research interests include: 1) surface/interface tuning of nanomaterials; 2) 2D materials and their heterostructures; 3) surface/interface electrochemistry.

Abstract

Developing sustainable renewable energy sources along with efficient energy storage and conversion systems is vital to address the global environmental and energy challenges. Two-dimensional (2D) nanomaterials and other materials with sheet-like morphologies possess unique physicochemical properties compared with their bulk counterparts, such as confined atomic thickness, high specific surface area and quantum confinement of electrons, which make 2D nanomaterials have great potential in electrochemical energy conversion and storage applications. Currently, many non-noble metal electrocatalysts for electrochemical water splitting are layered 2D materials, but their catalytic performance still cannot reach the level of noble metal electrocatalysts. Developing efficient strategies to further improve the electrochemical performance of 2D nanomaterials still remains a big challenge. Also, some electrochemically inactive 2D materials like RGO and g-C3N4 have great application potential in constructing hybrid electrocatalysts or battery electrodes. In this talk, I will be sharing some recent work on the design ofefficient 2D material-based nanostructures by surface engineering and interface/heterostructure engineering strategiesfor energy applications (electrocatalysis and batteries).
