Promotion by hydrous ruthenium oxide of platinum for methanol electro-oxidation

RuO2/MWCNT/ stainless steel mesh as a novel positive electrode in vanadium redox flow batteries

“…Compared to these electrocatalysts, RuO 2 not only has high stability in acidic solutions, but also has high electrocatalytic activity that may be suitable for VRFB applications [12,13].

Highly active Pt catalysts promoted by molybdenum-doped SnO2 for methanol electrooxidation

“…The Pt4f signals can be deconvoluted into three doublets, among which the most intensive doublet with binding energy (BE) at ca. 71.8 and 75.1 eV was a signature of Pt(0), while the other two doublets (72.7 and 76.0 eV, 74.0 and 77.3 eV) were signatures of Pt(II) and Pt(IV), respectively [22]. For all of the as-prepared [20], all of BEs of Pt in the as-prepared Pte(MoO 3 ) m SnO 2 /C catalysts shifted to higher values.…”

Fabrication of hollow platinum–ruthenium core–shell catalysts with nanochannels and enhanced performance for methanol oxidation

“…The decay of the current is ascribed to an increasing ratio of CO(ads) and oxygen donating species and a decrease of active sites poisoned by the poisoning species and intermediate products, such as CO ads , CHO ads and CH 2 OH ads [42,43]. As show in Fig.…”
