题 目:The marriage between catalysis and batteries
Abstract:
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.
