Platinum electrocatalysts with plasmonic nano-cores for photo-enhanced oxygen-reduction

Plasmonic Au–Pd Bimetallic Nanocatalysts for Hot-Carrier-Enhanced Photocatalytic and Electrochemical Ethanol Oxidation

“…Bimetallic nanocatalysts with a plasmonic component interact strongly with resonant photons, generating hot carriers at catalytically active noble metal sites to promote chemical transformations and enhance product selectivity [16][17][18]. Previous reports postulate that surface charge heterogeneity and transfer in bimetallic nanostructures can strengthen reactant adsorption, enhance product selectivity [4,5,[19][20][21], and increase the rate of H2 production [4,[22][23][24][25][26][27][28][29]. Strategically engineered bimetallic nanocatalysts present a transformative pathway to control electronic and optical properties to overcome current limitations in catalysis and selectively enhance reactions, such as the ethanol (EtOH) oxidation reaction (EOR).…”

Plasmon-promoted electrocatalytic water splitting on metal–semiconductor nanocomposites: the interfacial charge transfer and the real catalytic sites

“…The hydroxide semiconductors are conventional water splitting electrocatalysts, while the Au NPs with stable chemical properties and strong plasmonic activity act as visible light harvesters. [31][32][33] Before the water splitting experiments, we employed SERS to study the interfacial charge transfer between the hydroxide semiconductors and the decorated Au NPs in a semiconductor-metal-molecule hybrid system, where 2,6-dimethylphenyl isocyanide (DMPIC) was used as a probe molecule. DMPIC interacts with the metal surface via orbital hybridization and the strength of the N^C bond is affected by the electron abundance of the SERS substrates (Au NPs).…”
