Summary: A wet-chemistry reaction-adsorption strategy was used to fabricate Ru-Zn-La/ZrO2 catalysts for selective hydrogenation of benzene to cyclohexene. The catalyst preparation process was systematically investigated and verified. The reaction rate constants, selectivity, and catalytic behavior were found to be influenced by factors such as particle size, electron transfer effect, Zn species content, and surface hydrophilicity of the catalyst. A passivation treatment before the hydrogenation reaction significantly promoted cyclohexene selectivity.

Summary: Regulating the geometric and electronic configurations of interfacial active sites is an attractive approach to design high-efficiency catalysts. In this study, Ru/TMTFs-x catalysts with tunable chemical states were constructed by utilizing the electronic metal-support interaction (EMSI) and a 3D porous TiO2 nanoflower derived from 2D Ti3C2 MXene nanosheets. The catalysts exhibited high turnover frequency and excellent initial cyclohexene selectivity, which were attributed to the unique geometric architecture and EMSI-directed electron-deficient configuration of Ru, as well as the positive correlation between cyclohexene selectivity and the electron-deficient degree of Ru.

Summary: In this study, surface MoO3-decorated nanosized tetragonal zirconia (t-ZrO2) supports were utilized to immobilize Ru nanoclusters for the aqueous-phase HDO of anisole, achieving higher benzene selectivity. The presence of uniformly dispersed Ru nanoclusters and defective MoOx clusters on the t-ZrO2, forming strong Ru-MoOx interactions, led to the generation of abundant interfacial Ru delta+ species and oxygen vacancies, enhancing the adsorption of the methoxy group in anisole and the further demethoxylation to form benzene.

Summary: In this study, a highly efficient and stable catalyst (Cu/ZnOx/ZrO2) for CO2 hydrogenation to methanol was prepared using co-precipitation method with UiO-66 as a structural template. Cu/Zn was effectively combined and encapsulated in the channels of UiO-66, preventing the aggregation of Cu nanoparticles and phase separation of Cu and ZnO. The ZrO2 support derived from UiO-66 enhanced the interaction between the support and Cu/Zn, leading to significantly improved catalytic performance. The catalyst exhibited high space-time yield and good stability, outperforming commercial catalysts and most previously reported catalysts.

Summary: By treating with H-2-O-2 atmosphere, Ga species were prepared with high dehydrogenation capability, achieving an efficient balance of bifunctionality with ZSM-5 over Ga/ZSM-5 catalysts. The conversion rate of n-butane was increased, and the apparent activation energy of n-butane catalytic cracking was largely decreased. It was also found that O-2 treatment played a similar role in enhancing the catalytic performance, and the influence of different atmospheres on Ga species was investigated.

Summary: In this study, it was found that CoOx species on the catalyst support transform into Co-0 species, which is crucial for the selective dehydrogenation of propane to propylene. The transformation of CoOx is influenced by metal-oxide-support interactions and the presence of defective OH groups in ZSM-5-type zeolites. The presence of CoOx is also shown to inhibit coke formation and the developed Co/S-1 catalyst exhibited high activity.

Summary: Replicating the enzymatic surface microenvironment in vitro is challenging, but constructing an analogous model could facilitate our understanding of surface effects and aid in developing an efficient bioinspired catalytic system. In this study, five unique Cu2O morphologies were generated, and the surface morphology variations were found to be a consequence of differences in the exposure of low-index facets. The reactivity of Cu2O was found to be influenced by the proportion of {110} planes, with r-Cu2O exhibiting the highest reactivity.
