The marriage between catalysis and batteries

  Developing highly efficient electrocatalysts is becoming increasingly important to renewable energy applications, where novel methods to controllably tune the catalytic activities are highly desired. Inspired by Li ion battery studies with a wide range of electrochemical window, we have developed an electrochemical tuning method to controllably modify the electronic structures of catalytic materials, and thus significantly improve their activities in electrocatalysis. In this talk I will present a few successful examples including Li intercalation tuning of MoS2 for improved hydrogen evolution reaction, Li extraction tuning of LiCoO2 for improved oxygen evolution reaction, Li ion battery cycling of metal oxides for overall water-splitting catalysis, lattice strain tuning of Pt nanoparticles for modified oxygen reduction activities, and transition metal atoms in layered materials for highly selective CO2 reduction.

  Dr. Haotian Wang is currently a Rowland Fellow and principal investigator at Harvard University. He obtained his Bachelor of Science in the Department of Physics at USTC in 2011. After that he went to Stanford University for PhD studies and received the degree in 2016. He was awarded the Rowland Fellow foundation and was selected as the early career advisory board of Nano Letters in 2016. He received the Materials Research Society graduate student award and the Chinese Government Award for Outstanding Self-Financed Students Aboard in 2015.
