Localized surface plasmon enhanced electrocatalytic methanol oxidation of AgPt bimetallic nanoparticles with an ultra-thin shell

Abstract

AgPt bimetallic hollow nanoparticles (AgPt-BHNPs) with an ultra-thin shell were synthesized.

Fundamentals and applications of photo-thermal catalysis

“…270 In the same year, Yang and co-workers reported the synthesis of AgPt bimetallic hollow nanoparticles, and they tested this material for LSPRenhanced methanol oxidation. 271 Linic and co-workers prepared another photo-thermal catalyst consisting of silver nanocubes supported on Al 2 O 3 , and they tested it for commercially relevant catalytic oxidations, which are normally performed at high temperatures and over expensive platinum-group metals. 49 Zhang and co-workers investigated the effect and the mechanism of the photo-thermal enhanced catalytic oxidation of formaldehyde promoted by a graphene-based MnO 2 composite.…”

Rational Design of Bimetallic Au/Cu Nanostructure: An Efficient Catalyst for Methanol Oxidation

“…Noble metals like Au, Pt, and Ag have emerged as highly active electrocatalysts compared to other non‐noble metal or metal oxides for methanol oxidation [10a,11b,20–21,30b,43] . However, few bimetallic alloys have been employed in methanol oxidation as cost‐effective catalysts [32b,34–35] .…”

Recent Advances in Plasmonic Nanostructures for Enhanced Photocatalysis and Electrocatalysis

“…In the past few years, some examples of plasmon‐enhanced AOR have been reported but the mechanism remains controversial. [ 185–190 ] The plausible mechanisms of plasmon‐enhanced AOR include: 1) hot hole serves as the active center for the oxidation of alcohol, 2) hot electron prevents Pt and Pd from CO poison, and 3) photothermal effect. Notably, Au‐based nanostructure is catalytically active for AOR and therefore can be employed as catalyst for direct plasmon‐enhanced AOR, and process (2) can be excluded as the bond between Au and CO is very weak.…”
