The support's reducibility and CO₂ uptake increased with Ce content, arising from oxygen vacancies created upon surface reduction. Co/Al was the most active (29% CO₂ and 18% CH₄ conversion at 650 °C), and the activity and selectivity (H₂/CO) decreased with Ce concentration due to ceria's propensity for RWGS and/or the Co size increase upon Ce incorporation (after reduction, from 13 nm for Co/Al to 36 nm for Co/20Ce–Al). Co/Al deactivated the most by carbon accumulation (4.6 wt%, 7 h stability test, 650 °C), as the support provided no O for CH_<em>x</em> oxidation (<em>x</em> = 0–3). Introducing Ce improved the carbon content and stability under thermal conditions due to ceria's oxygen release capacity from oxygen vacancies (0.78 wt% for Co/5Ce–Al).

Photocatalysts are a class of compounds with exceptional properties, making them suitable for various applications in environmental remediation.

Experiments were conducted at a pressure of 110 Torr over a temperature range of 873–1173 K. Stable products, including alcohols, aldehydes, ketones, and C₃ hydrocarbons, were quantified using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS). Methyl and ethyl radicals were definitively identified, emphasizing their critical role in the formation of C₂–C₃ hydrocarbons. Based on these speciation results, a microkinetic model for the OCM reaction over Li/MgO was developed. The reaction network analysis revealed that the main pathway for CO_<em>x</em> generation involves the conversion of CH₃ to CH₃O(s)/CH₃O through surface and gas-phase reactions. Gas-phase reactions also promote the deep oxidation of C₂H₄. Sensitivity analysis indicated that methane activation is primarily governed by surface reactions, while the coupling of CH₃ to form C₂H₆ is mainly driven by gas-phase reactions. Both surface and gas-phase reactions contribute equally to the formation of C₂H₄. Additionally, the pressure dependence analysis demonstrated that the high-pressure limit of the CH₃ coupling reaction restricts the increase in C₂ yield as pressure rises. In conclusion, this study provides a comprehensive investigation into the OCM speciation pool, develops a microkinetic model aligned with experimental findings, and elucidates the reaction network driven by free radicals.

The silica-supported Cu/Mo₂CT_<em>x</em> (MXene) catalyst displayed higher activity than the industrial reference system Cu/ZnO/Al₂O₃. To better understand CO₂ hydrogenation in Cu/Mo₂CT_<em>x</em> and related processes under reaction conditions (CO hydrogenation and reverse water gas shift reaction), we performed periodic DFT calculations to evaluate the methanol synthesis reaction mechanism using our previously calibrated theoretical model against experiment characterization. Our results show the crucial role played by the Cu/Mo₂CT_<em>x</em> interface in providing low-energy pathways to facilitate the hydrogenation of CO₂ to methanol, where both the Cu atom and the Mo₂CT_<em>x</em> support participate in the reaction mechanism. The findings showcase the unique pathways provided by this supported single-atom catalyst, allowing the successive heterolytic cleavages of molecular hydrogen (H₂) to form HCOO*, HCOOH*, and H₂COOH* species with co-adsorbed hydrogen in contrast with classical heterogeneous catalysts based on Cu NPs supported on oxides. Thus, CH₃OH is readily formed under reaction conditions. CO also forms <em>via</em> the reverse water-gas shift (RWGS) reaction, which can be hydrogenated to methanol.

In order to demonstrate a case study to overcome this issue, we attempted to screen chiral backbones and substituents of CPAs by quantum chemical calculations for the kinetic resolution of racemic γ-hydroxy esters with a stereogenic centre at the <em>γ</em>-position through a lactonisation reaction. In constructing the theoretical prediction model, representative reaction pathways based on the two-step reaction mechanism of lactonisation were considered, and CPA candidates were screened rationally and efficiently without having to perform an exhaustive search for plausible reaction pathways by DFT (density functional theory) calculations. As a result, the selectivity factor (<em>s</em>-factor) was increased by using the predicted CPA with reduced computational load and experimental effort. This prediction model has a downside to be considered because some energetically unfavourable reaction pathways were ignored to simplify the model.

The photoconductivity-lifetime product shows a good correlation with the conversion of benzyl alcohol and the yield of benzaldehyde, with CuO/Cu₂O exhibiting the highest performance. The favorable behavior of charge carriers in CuO/Cu₂O for photocatalysis is attributed to the presence of CuO impurity, which enables more efficient separation of photoexcited electrons and holes <em>via</em> the S-scheme heterojunction. The charge carrier mobility and photocatalytic performance are strongly influenced by the optoelectronic properties rather than by physical properties. By introducing a small amount of CuO (5.3 mol% based on X-ray absorption near edge structure), the charge carrier mobility of Cu₂O is improved, enhancing performance even when the specific surface area decreases.
