Abstract

In recent years, graphene-based materials are gaining considerable attention as novel materials for environmental applications because of their distinct advantages over other carbon materials. Three-dimensional (3D) nanoporous graphene materials have particularly become one of the most active research fields in the last three years. Some of the key attributes of these materials are their well-defined porous structure (high surface area and high pore volume), hydrophobicity and ease of regeneration for their repeated use. These characteristics together with the unique physicochemical properties of two-dimensional (2D) graphene, notably its high electronic and thermal conductivity, and great mechanical strength, can lead to effective technologies to address the pressing global environmental challenges such as “carbon capture and utilization” and “water purification”. This presentation will discuss the major outcomes of our research efforts on the synthesis, characterization and applications of 3D graphene- based materials in the environmental field and also point out new research directions for further development of these materials to promote sustainability.

Speaker's bio

Rajasekhar Bala has been a faculty member at NUS since 1996. Prior to joining NUS, he worked at the New York State Department of Health and at Brookhaven National Research Laboratory, USA as a scientist. Prof Bala has broad research interests ranging from urban air quality to climate change mitigation. He and his research group have published 200 research articles in international journals. He has led several multi-national, multi-disciplinary research projects successfully over the years. He is the Editor of the International Journal of Aerosol and Air Quality Research and currently serves as the guest editor of the special issue with the theme “PM2.5 in Asia”. In recognition of his excellence in research and teaching, Prof Bala has received a number of research and educator awards including the Alan Berman Research Publication Award from the US Department of the Navy (2014) and two research awards from the Institution of Chemical Engineers (2015).
