Promoting effects of Fe 2 O 3 to Pt electrocatalysts toward methanol oxidation reaction in alkaline electrolyte

Carbon‐Free Nanocoral‐Structured Platinum Electrocatalyst for Enhanced Methanol Oxidation Reaction Activity with Superior Poison Tolerance

“…The ratio between forward and backward peak current indicates poison tolerance . Therefore, the poison tolerability of ncs‐Pt was analyzed from the forward and backward peak current ratio ( j f /j b ).…”

Addition of iron oxide to Pt-based catalyst to enhance the catalytic activity of ethanol electrooxidation

“…Iron and iron oxide have recently gained attention because they can be used as co-catalyst or conductive support during the oxidation of alcohols. Few researchers have employed these materials to oxidize methanol [50][51][52][53], ethanol [54][55][56][57], or glycerol [58]. Iron and Fe 2 O 3 are advantageous co-catalysts or supports for Pt-based catalysts: they are inexpensive as compared to other metal oxides, and they present excellent physicochemical properties, such as high surface, porosity, and electropositivity, which enhances the activity of Ptbased catalysts and contributes to the occurrence of electronic and bifunctional mechanism over Pt.…”

Reduced graphene oxide (RGO)-supported Pd–CeO2 nanocomposites as highly active electrocatalysts for facile formic acid oxidation

“…36 Apart from the addition of a second metal in the case of bimetallic nanoparticles, the utilization of metal oxides as promoters/supports to noble-metal electrocatalysts has also gained significant interest because of their advantages, such as environmentally benign nature, low-cost and promising stability especially in an acidic environment. 37,38 For example, Pt nanoparticles deposited on the MnO 2 -MWCNT composite support show superior activity compared with the Pt/MWCNT support. 39 Recently, Feng and co-workers reported that the electronic structure of Pt can be modulated by using MnO 2 with different morphologies as the promoter and the resulting manganese oxide-promoted Pt catalyst showed promising methanol oxidation activity and stability.…”
