Themed collection Catalysis Science & Technology 10th Anniversary Symposium

The frontiers between homogeneous and heterogeneous catalysis are progressively disappearing.

Distinct local environments for atomically dispersed Rh species on anatase TiO₂ result from reduction treatments under CO and H₂.

NO has been catalytically converted by Ce-UiO-66 and bimetallic Ce/Zr-CAU-24.

A covalent triazine framework coated on glassy carbon electrode performs high catalytic activity towards the ORR.

By taking full advantage of the α-Fe₂O₃/Ag/CdS ternary heterojunction in charge separation and transfer, light harvesting and electrocatalytic water oxidation, obviously improved water oxidation performance was achieved on the photoanode.

Olefin polymerization starts at the outer surface and at the macropores walls. Here fragmentation occurs by peeling off the catalyst in a layer-by-layer mode with, in ideal conditions, the simultaneous formation of bisection-type fractures across the catalyst inner domains.

Fe-BiOCl nanosheets exhibited 3.1 times enhanced photoactivity, which was attributed to the Fenton-like reaction and the better charge separation, thus more reactive oxygen species (˙OH and ˙O₂⁻) involved in the photodegradation process.

Surface alkalinized Ti₃C₂ MXene with high electronic conductivity and CO₂ adsorption/activation ability is used as an efficient co-catalyst for boosting the photocatalytic activity of ZnO for CO₂ reduction into hydrocarbon solar fuels.

para-xylene and light olefins are co-produced in CO₂ hydrogenation in the presence of toluene over OXZEO composite catalyst.

In situ/operando spectroscopic experiments and DFT calculations unravel the redox mechanism of NH₃-SCR over Cu-AFX zeolites.

Copper supported on KIT-6 mesoporous silica was prepared via ammonia evaporation (AE) method and applied for the catalytic hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG).

Multiple linear regression modelling is used to analyse in situ Raman spectra recorded during a “CO-free” Pauson–Khand type cyclisation which enables a knowledge-driven optimisation protocol.

Au NP catalyst combined with triethylphosphite, P(OEt)₃, is remarkably more reactive than solely Au NPs for the selective deoxygenation of epoxides to alkenes.

The TiO₂ support composition and the reduction method impact both metal–support interaction and Ru nanoparticle size driving the catalyst performances in succinic acid hydrogenation.

The reaction scheme of the Fries rearrangement of aryl esters over zeolite catalysts strongly depends on the framework type, acidic properties, and substrate identity.

The functionality of the UiO-66(Zr) linkers affects the number of defects on the Zr6 clusters, leading to differences in the MOFs' Brønsted acidity, which promotes the dehydration of fructose into HMF.

DFT calculations suggest that Cu(I) oxidation with O₂ as the sole oxidant plays a major role in the oxidation half cycle of standard NH₃-SCR over Cu-CHA zeolites.

The presence of capping ligands can block the adsorption of the amine ligand on gold NPs, preventing the formation of a ligand–metal interface able to activate H₂ for selective hydrogenation reactions.

A dual system featuring ZrO₂-supported CeO₂ and Ca-doped Al₂O₃ catalysts enables the direct production of vinyl chloride via ethene oxychlorination.

Addition of tungsten to supported platinum catalysts increased the rate of benzyl alcohol hydrodeoxygenation via a bifunctional mechanism, whereas undesirable decarbonylation was suppressed due to blocking of platinum terrace sites.

Cu/Co(OH)₂ was prepared from an in situ method and the electrostatic interaction arising from the MSI was controlled by the Cu/Co ratio. The optimized catalyst exhibits a high catalytic performance for AB methanolysis.

A sustainable method to synthesize allyl ethers from allyl alcohol by the simple mixing of TiO₂ and MoO₃ catalysts.

Phosphine-scavenging Merrifield resins can significantly facilitate the synthesis of highly active Ru metathesis catalysts, including the second-generation Grubbs, Hoveyda, and indenylidene catalysts (GII, HII, InII).

Although the local geometry of Mo in Mo/HZSM-5 has been characterized before, we present a systematic way to manipulate the configuration of Mo and link it to its catalytic properties.

Propylene glycol is converted to acrylic acid via dehydration to allyl alcohol. A process flow scheme is proposed, based on distillation resistance.

A bifunctional catalyst was designed to directly and selectively hydrogenate CO₂ to ethylene and propene with a high selectivity of 80–90% in hydrocarbons by combining the synthesis of methanol and methanol-to-olefins processes.
