报告简介：

Electrochemical water splitting to produce hydrogen and oxygen is an important process for many energy storage and conversion devices. It is essential to develop efficient, low-cost and earth-abundant, and durable electrocatalysts for both OER and HER. Bimetallic sulfides, nitrides, and phosphides are under intensive research and proven to be promising replacements of the precious noble metals. Metal nitrides are among the most suitable non-noble metal commercial catalysts, because the introduced N atoms strongly affect the electronic structure of the metal hosts by charge transfer processes and/or concomitant structural modification. In traditional synthesis methods, caustic and hazardous ammonia (NH3), long processing duration (1~4 h) and high reaction temperature are indispensable.
We have employed N2 RF plasma for fast and low-temperature synthesis of metal nitrides. Three examples will be given. 1) CoN nanowires array by converting the pre-synthesized Co3O4 nanowires with N2 plasma reaction in 1 min for OER. 2) NiMoN dendritic nanostructures by treating electrodeposited metal alloy for HER. 3) Converting commercial carbon cloth by plasma to be supercapacitive and Li-ion storage material. Our research provides a new methodology to synthesize metal nitrides for various applications such as catalysts, supercapacitors and batteries..
