Synergistic effect between noble metal M (M = Pt, Pd, Rh) and polyoxometalate solution (H_3PMo_(12)PO_(40)) to catalyze and oxidize butanol under thermal condition and their application in the fuel cell

摘要

Liquid fuel cell used butanol as fuel was reported by the synergistic catalytic effect of H_3PMo_(12)O_(40) polyoxometalate solution (POM) and noble metal M (M = Pt, Pd, Rh). Under thermal condition, chemical reaction energy level was decreased. Butanol was oxidized into organic acid and H_3PMo_(12)O_(40) polyoxometalate was reduced to H_4PMo_(12)O_(40) polyoxometalate. According to this principle, butanol could generate electricity in the fuel cell device. Compared to the three different noble metals of Pt, Pd, Rh, the catalytic effect of Pt was the best. The maximum output power density of liquid fuel cell could be up to 40.38 mW/cnr. The products had been characterized by GC-MS. During the catalytic process, the rearrangement of molecule for the oxidized products was happened.
