Pd supported on Co@CN derived from ZIF-67 as catalyst for hydrogen generation from formic acid

Abstract Hydrogen generation from formic acid(FA)is a promising route in hydrogen energy supply, and catalyst is considered to be the key to this process. Herein, Pd nanoparticles assembled on porous carbon (Co@CN) which derived from ZIF-67, wherein Co species inherited from precursors plays as assistant to adjust the electronic and structure of Pd. In addition, the N atom on the porous carbon skeleton also modified the electronic state of Pd and promoted the anchoring of Pd nanoparticles. The as-synthesized catalyst (Pd/Co@CN) acquired high activity (TOF of 1403 h-1) and stability toward decomposition of FA at 30℃.
