Title
Au and Pt nanoparticle supported catalysts tailored for H2 production: From models to powder catalysts
Abstract

•Au and Pt supported oxide catalysts are of great importance to target H2 production from water–gas-shift, oxygenate steam reforming and solar-assisted reactions.•Surface science and theoretical methods of model and powder catalysts have been described to correlate the structure and reactivity.•Size, geometry, oxidation state and electronic transfer of Au and Pt nanoparticles, and strong metal-support interactions drive the catalytic reactivity including yield, selectivity and deactivation.

The use of metal nanoparticles (NPs), including Au and Pt, supported over oxides has been pivotal, and is ever increasing in enabling catalytic reactions which target the production of hydrogen. We review here the most recent works pertaining to the fundamental understanding of the structure, morphology, growth, characterization, and intrinsic phenomenological properties of Au- and Pt-based catalysts that influence the reactivity and selectivity to target hydrogen production. We draw on surface science and theoretical methods of model and powder catalysts using high resolution imaging, spectroscopy, scattering experiments, and theoretical studies. Based on these insights we identify key aspects of studies of supported metal nanoparticle (NP) catalysts for several reactions. The main focus of this review is on the intersection of catalytic chemistry related to the water-gas shift (WGS), oxygenate steam reforming (OSR), and solar-assisted reactions (SAR).
