In situ/operando studies provide unique information about the active phase of catalysts used for hydrogen production through the water-gas shift reaction.

A personal perspective is offered on the state of the art of our current understanding of the mechanism of olefin hydrogenations promoted by transition-metal catalysts.

This paper describes the design, characterization, and utilization of branched TiO₂ nanoarrays sensitized with CdS quantum dots as anodes for photoelectrochemical water splitting.

Benzene adsorption does not change the segregation state of the catalyst, and d-band models predict benzene adsorption energy well.

We report a novel synthesis of nanoparticle Pd–Cu catalysts, containing only trace amounts of Pd, for selective hydrogenation reactions.

Co-processing CH₄ and biomass-derived oxygenates in an attempt to couple CH₄ dehydrogenation with biomass deoxygenation results in a staged bed with upstream reforming and downstream dehydroaromatization of CH₄.

Temperature programmed desorption reveals a competition between ethylene glycol dehydration and dehydrogenation on TiO₂(110).

Ge dramatically reduces the dehydrogenation temperature for LiH to just 270 °C through forming a series of lithium germanides.

Benzyl alcohol oxidation using supported AuPd alloy nanoparticles is investigated using in situ ATR-IR, DRIFT and inelastic neutron scattering spectroscopies.

Comparative studies of the effect of oxide supports in stabilizing desirable Pt–Ni bimetallic structures show that the catalytic activity is PtNi/γ-Al₂O₃ ≫ PtNi/TiO₂ for hydrogenation while PtNi/γ-Al₂O₃ < PtNi/TiO₂ for reforming.

Cu nanoparticles have been supported on aluminosilicate materials and succesfully employed as catalysts in the microwave-assisted conversion of glucose into valuable products via tandem formic acid-promoted dehydration (to 5-hydroxymethylfurfural—HMF) and further selective hydrogenation to 5-methylfurfuryl alcohol (MFA).

Based on density functional theory calculations, we present mechanisms underlying the improvement in the catalytic performance of Pd-based alloys for oxygen hydrogenation to water by a thorough analysis of intra and interlayer orbital interactions.

‘High pressure’ is required to oxidize a vanadia thin film.

A Ni/SiO₂ catalyst with fewer defects shows better sulfur resistance for CO methanation.

Operando Raman spectroscopy revealed that the addition of H₂ alters the chemical nature of coke deposits on a Pt-based propane dehydrogenation catalyst.

Extended LHHW kinetic models are able to predict perfectly the performance of integral reactors during ammonia decomposition without considering any change of the mechanism of reaction.

Bond selectivity is coverage dependent for n-butane dissociation on PdO(101), with primary C–H bond cleavage strongly favored at low coverage.

NiS surface modified CdS nanorod p–n junction photocatalysts exhibit enhanced visible-light photocatalytic H₂-production activity.

Build up Fe₂(MoO₄)₃ with addition of MoO₃ monolayers to Fe₂O₃. Ultimately, when ferric molybdate formation is saturated, a complete layer of molybdenum oxide forms at the surface.

Water facilely dissociates on the Fe(II)_CUS cations at the FeO(111)–Pt(111) interface to form hydroxyls that can react with CO(a) on the neighbouring Pt(111) sites to produce CO₂ at low temperatures.

Pt impregnated on a Sn-beta catalyst results in a very promising catalyst for the selective hydrogenation of α,β-unsaturated aldehydes, compared to the PtSn co-impregnated beta catalysts.

The origin of visible-light absorption and photoactive enhancement for the B-, C- and B/C-doped TiO₂ is investigated by first-principles.

Photocatalytic H₂ production using TiO₂ was demonstrated using Ni(NO₃)₂ as an additive, giving a H₂-production rate of 2547 μmol h⁻¹ g⁻¹ with a quantum efficiency of 8.1%.
