Description

The lack of  sustainable and efficient  catalysts for many renewable energy  applications (e.g., fuel cells and water splitting) and the unabated negative environmental impacts of fossil  fuels remain among  the most pressing issues facing  the world  today. In  this talk I will  discuss  my  research  group’s  recent   effort s  on the  synthesis of heteroatom­doped  metal­free or noble metal­free nanoporous and mesoporous carbon,  metal oxide and  carbon/metal oxide hybrid materials  that exhibit  high catalytic and electrocatalytic activity for reactions such as oxygen reduction reaction, hydrogen evolution reaction, and hydrazine oxidation—reactions that are relevant to fuel cells, water splitting, renewable energy, and so on. The  catalytic activity of some of  these materials is comparable or better  than  platinum­based catalyst s, conventional catalysts that are widely used for such reactions but are deemed unsustainable due to their scarcity and high cost. Our findings, which  defy  the conventional  paradigms, are  also import ant   for  fundamental studies in the current state­of ­the­art  of catalysis  that rely only on met allic syst ems. In  the last  part of my  talk, I will describe novel design and “nanost ruct uring” approaches  for a series of core-shell nanostructured materials  with efficient catalytic or electrocatalytic  activities for water splitting, hydrogen evolution and oxygen reduction reactions.
