Summary
Hydrogen has emerged as a green and sustainable fuel to meet the demand for future global energy. Nowadays, the majority of hydrogen is still produced from steam-reformed methane, which is derived from limited fossil resources and greatly increases CO2 emissions. Electrocatalytic hydrogen evolution reaction (HER) enabled by renewable electricity holds great promise as a safe, scalable, low-cost, and environmentally friendly pathway for hydrogen production. In this talk, I will summarize and discuss our recent work for the development of interface controlled nanocatalysis for HER, including the fine control over the oxidation states of single-atom Pt catalysts through electronic metal–support interaction that significantly modulates the catalytic activities in either acidic or alkaline HER, the construction of two-dimensional covalently bonded fullerene polymeric network (PNW-C60) supported platinum nanoparticles (Pt NPs) as a highly active and stable ammonia oxidation reaction electrocatalyst for hydrogen production from green ammonia, etc.
