Dataset for the publication: Non-oxidative conversion of methanol to dimethyl ether, methyl formate and dimethoxymethane over Cu/Hβ catalyst: Tailoring product selectivity
<p>The dataset covers the research data of the publication in ChemCatChem with the title "Non-oxidative conversion of methanol to dimethyl ether, methyl formate and dimethoxymethane over Cu/Hβ catalyst: Tailoring product selectivity" (DOI: <a href="https://doi.org/10.1002/cctc.202301704">10.1002/cctc.202301704</a>). The provided data comprehend the main experimental data obtained in the study including material characterisation (XRD, CO-DRIFTS, H2-TPD, pyridine IR, N2 physisorption) and the catalytic data of the investigated Cu-loaded zeolites in a continuous gas-phase fixed-bed reactor.</p>

Reaction-Induced Metal-Metal Oxide Interactions in Pd In2O3/ZrO2 Catalysts Drive Selective and Stable CO2 Hydrogenation to Methanol
<p>Ternary Pd-In<sub>2</sub>O<sub>3</sub>/ZrO<sub>2</sub> systems hold promise as industrial catalysts for CO<sub>2</sub>-based methanol synthesis, but maximization of their productivity requires appropriate structuring of the active phase, promoter, and carrier. Here, we report that Pd-In<sub>2</sub>O<sub>3</sub>/ZrO<sub>2</sub> systems prepared by impregnation evolve into a unique catalyst architecture under CO<sub>2</sub> hydrogenation conditions, leading to selective and stable behavior. Detailed space and time-resolved <em>operando</em> characterization and simulations reveal that the restructuring process, completed within the first 30 min under reaction conditions, is governed by the energetics of metal-metal oxide interactions. The resulting architecture comprises InPd<em><sub>x</sub></em> alloy particles decorated by InO<em><sub>x</sub></em> layers, whose proximity is crucial to avoiding performance losses typically observed when palladium agglomerates. The findings highlight the potential beneficial role of reaction-induced restructuring in advancing catalyst design.</p>
Kinetics of Photoelectrochemical Oxidation of Methanol on Hematite Photoanodes
<p>The kinetics of photoelectrochemical (PEC) oxidation of methanol, as a model organic substrate, on α-Fe<sub>2</sub>O<sub>3</sub> photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements. Methanol is oxidized on α-Fe<sub>2</sub>O<sub>3</sub> to formaldehyde with near unity Faradaic efficiency. A rate law analysis under quasi-steady-state conditions of PEC methanol oxidation indicates that rate of reaction is second order in the density of surface holes on hematite and independent of the applied potential. Analogous data on anatase TiO<sub>2</sub> photoanodes indicate similar second-order kinetics for methanol oxidation with a second-order rate constant 2 orders of magnitude higher than that on α-Fe<sub>2</sub>O<sub>3</sub>. Kinetic isotope effect studies determine that the rate constant for methanol oxidation on α-Fe<sub>2</sub>O<sub>3</sub> is retarded ∼20-fold by H/D substitution. Employing these data, we propose a mechanism for methanol oxidation under 1 sun irradiation on these metal oxide surfaces and discuss the implications for the efficient PEC methanol oxidation to formaldehyde and concomitant hydrogen evolution.</p>
