Enhanced activity of molybdovanadophosphoric acid modified Pt electrode for the electrooxidation of methanol

Pt–Ru/Al2O3–C nanocomposites as direct methanol fuel cell catalysts for electrooxidation of methanol in acidic medium

“…8. All the catalysts displayed an initial fast current decay, which can be attributed to the poisoning of the catalysts by intermediate species, such as CHO ads and CO ads , etc., 48,49 formed during the methanol oxidation reaction. Considering the different initial current values exhibited by the catalysts, the current obtained at 700 s was normalized to the initial current to compare the stability of the catalyst systems.…”

Ni2P enhances the activity and durability of the Pt anode catalyst in direct methanol fuel cells

“…The introduction of an earth-abundant and non-precious co-catalyst is an effective approach to improve the catalytic activity and durability as well as to lower the cost of Pt-based catalysts. 3,6,8,9 Several metal oxides such as WO x , 10,11 MoO x , 12,13 CeO 2 , 14,15 and SnO 2 , 16 as well as main group elements such as P (ref. 17) and N, 18 have been used to promote Pt in methanol oxidation.…”

The enhancement effect of nitrogen, fluorine-codoped titanium dioxide on the carbon supported platinum nano-catalyst for methanol electrooxidation reaction

“…The introduction of an earthabundant and non-precious co-catalyst is an effective approach to improve the catalytic activity and durability as well as to lower the cost of Pt-based catalysts [5,8]. One approach is to introduce novel materials, such as SnO 2 [9,10], WO x [11,12], MoO x [13,14], and CeO 2 [15,16], as supports. Another way is to dope the carbon support with main group elements such as P [17] and N [18].…”
