By a News Reporter-Staff News Editor at Energy Weekly News -- Investigators discuss new findings in Alcohols. According to news reporting originating in Harbin, People's Republic of China, by VerticalNews journalists, research stated, "In this work, Pt nanoparticles are deposited on NbO2-modified carbon composites and evaluated as promising direct methanol fuel cell (DMFC) electrocatalysts. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) indicate that Pt nanoparticles (about 2.5nm) are uniformly dispersed on NbO2-modified carbon composites."
The news reporters obtained a quote from the research from the School of Chemical Engineering and Technology, "Electrochemical measurements show that the mass activity toward methanol electrooxidation on Pt/NbO2-C is as high as 3.0 times that of conventional Pt/C. Meanwhile, the onset potential of CO oxidation is negatively shifted by about 46mV as compared with that of Pt/C, which means that the synergistic effect between NbO2 and Pt facilitates the feasible removal of poisoning intermediate CO during methanol electrooxidation. X-ray photoelectron spectroscopy (XPS) characterizations reveal the electron transfer from Nb to Pt, which suppress the poisoning CO adsorption on Pt nanoparticles and facilitate methanol electrooxidation."
According to the news reporters, the research concluded: "NbO2 nanoparticles facilitate methanol electrooxidation on Pt/C catalyst by synergistic effect and electronic effect, which represents a step in the right direction for the development of excellent fuel cell anode electrocatalysts."
