Stable and active methanol oxidation via anchored PtRu alloy nanoparticles on NiFe layered double hydroxides

Abstract

Enhancing the catalytic efficiency of the methanol electro-oxidation reaction (MOR) holds paramount importance in expediting the commercialization of direct methanol fuel cells (DMFCs). In this study, we unveil a novel...

Amorphous conversion in pyrolytic symmetric trinuclear nickel clusters trigger trifunctional electrocatalysts

“…The resulting CV curve exhibits two distinct oxidation peaks, with the forward peak current ( I f ) during forward scanning and reverse peak current ( I b ) during reverse scanning occurring around 0.55 V. I f is associated with the formation of intermediate product CO during methanol oxidation, while I b corresponds primarily to the oxidation of adsorbed intermediate species that are not fully oxidized. 37 The peak current density of c325 is notably the highest at 1358 mA cm −2 , surpassing that of a250 (388 mA cm −2 ), a285 (490 mA cm −2 ), and a300 (453 mA cm −2 ) ( Fig. 4d ).…”

Ultrafine Pd3Pb intermetallic nanowires with Mott–Schottky effect achieve a complete oxidation pathway for methanol oxidation catalysis

“…In this regard, as an efficient, highly secure, portable and eco-friendly energy conversion device, a direct methanol fuel cell (DMFC) can achieve efficient energy conversion under low-temperature conditions, which can be applied to alleviate the energy crisis and is considered a potential green energy converter device in the future. 7–13…”
