摘要
Electrocatalystsplay a prominent role in the renewable energy conversion and storageapplications, including hydrogen evolution reaction (HER), oxygen evolutionreaction (OER), oxygen reduction reaction (ORR), and carbon dioxide reduction(CO2RR). Here we will briefly introduce our recent work in developing some ofthese electrocatalysts [1-5], together with theoretical calculations forrational structure designs and reaction mechanism understandings. Severalrepresentative examples using earth-abundant metal (hydro)oxides and carbonsinclude: (1) hybrid hydroxide nanowire-nanoflake assembly for bifunctionalHER/OER, (2) metal oxide@carbon superlattices for bifunctional HER/OER, (3)mesoporous oxide@carbon for bifunctional ORR/OER, and (4) tuning of nitrogendoping types in carbon nanostructures for CO2RR. Attributed to their highelectrochemically active surface area, fast charge transport, efficient masstransfer and gas release, these nanostructured electrocatalysts enable muchenhanced activity, such as reduced overpotentials, high current densities andlong stability. In addition, we also demonstrate that by reversing the catalystdesign concepts, new battery electrodes with substantially enhanced energystorage density and power density can also be realized [6].
