The phosphorous-promoted Cu-Ti oxide (Cu-Ti-P) catalysts, Cu(1.0 mol%) and P(1.0, 2.0, and 4.0 mol%)-incorporated into the framework of Ti(1.0 mol%)O2, that were synthesized using a solvothermal method in the present study, and used for their potential compatibilities in methanol steam reforming. Comparative experiments in methanol oxidative steam reforming were also conducted over γ-Al2O3 support. The Cu-Ti-P/γ-Al2O3 catalyst provided significantly higher methanol reforming reactivity compared to that without P component, and the tendency was similar to the existence of γ-Al2O3 support. We suggest a mechanism that P component plays an important role of encouraging the Brnsted acid sites, resulted to strongly partial oxidation and thermal cracking of methanol to acetaldehyde and CO2 respectively, eventually, it makes increasing the hydrogen yield and suppressing CO generation. |
