Pd@C3N4 nanocatalyst for highly efficient hydrogen storage system based on potassium bicarbonate/formate. Issue 7 (22nd March 2016) - Shao, Xianzhao
Abstract : Formate/bicarbonate system has several desirable properties such as noncorrosive and nonirritating nature, as well as facile handling, which make it an attractive candidate for a safe, reversible hydrogen storage material. Herein, Pd nanoparticles supported on mesoporous graphitic carbon nitride (mpg‐C3 N4 ) for formate‐based reversible hydrogen storage is reported. The as‐developed Pd/mpg‐C3 N4 material was shown to be a superior catalyst for the hydrogenation of high concentrations of bicarbonate to formate under mild conditions. The effects of reaction temperature, H2 pressure, and bicarbonate concentration on the hydrogenation of bicarbonate to formate were investigated. The catalytic performance remained steady with high activity up to six hydrogenation cycles. The interaction between mpg‐C3 N4 and Pd nanoparticles and the concerted effects of the nitrogen species located at mpg‐C3 N4 and bicarbonate played a synergetic role in the enhancement of the performance of the catalyst for hydrogenation. © 2016 American Institute of Chemical Engineers AIChE J, 62: 2410–2418, 2016
