A highly active and stable Pd/MoC catalyst for hydrogen production from methanol decomposition

( )Methanol decomposition is a promising method to produce clean hydrogen fuel. However, it requires developing highly active and stable catalysts at low temperature. Herein, a series of Pd/MoC catalysts were prepared and evaluated for hydrogen production from methanol decomposition. Detailed characterization data indicated that more alpha-MoC1-x phase and highly dispersed Pd particles were obtained in Pd/MoC catalysts with lower Pd loading, which exhibited superior catalytic efficiency for hydrogen production. Specifically, the catalytic activity of 0.5Pd/MoC catalyst, whose average turnover frequency reached up to 807 mol(H2).mol(pd)(-1) h(-1) at 160 degrees C, was much higher than that of traditional CuZnAl catalyst that was almost inactive at the same reaction conditions. More importantly, the 0.5Pd/MoC catalyst exhibited a very stable catalytic performance for hydrogen production from methanol decomposition at all test temperatures. This could be attributed to the presence of strong interaction between the Pd particles and alpha-MoC1-x phase on the 0.5Pd/MoC catalyst.

Automated summary

A series of Pd/MoC catalysts were prepared and evaluated for hydrogen production from methanol decomposition, with 0.5Pd/MoC catalyst showing superior catalytic efficiency and stability compared to traditional CuZnAl catalyst. Strong interaction between Pd particles and alpha-MoC1-x phase on the 0.5Pd/MoC catalyst contributed to its stable catalytic performance.
