The development of active and earth-abundant catalysts for energy storage and chemicals/fuels production is becoming increasingly important, particularly in fundamental electrochemical reactions including water splitting, fuel cell catalysis, and carbon dioxide reductions. Engineering the electronic structures of catalytic materials for proper binding with reaction intermediates is critical to deliver optimized performances. In this presentation I will first introduce the unique synergy between catalysis and battery technologies for a systematical and controllable tuning of material properties and thus their catalytic activities. This includes the Li-ion tuning of oxidation states in 2D materials and battery cycling tuning of grain boundaries in metal-oxides for improved water splitting, as well as the battery electrode tuning of Pt lattice strain for controllable fuel cell catalysis.
