Summary: The appropriate metal-support interaction plays a crucial role in the supported Fischer-Tropsch catalysts. By synthesizing a series of porous spinel MAl2O4 together with Al2O3, and using them as supports for Co-based Fischer-Tropsch synthesis catalysts, the study investigated the influence of metal-support interaction on Co dispersity, reducibility, and catalytic performance. The results demonstrated that 15Co/CoAl2O4 showed the highest activity and C5+ selectivity due to weaker metal-support interaction, leading to higher reducibility and CO dissociation ability.

Summary: This study reports the use of Na-mediated bimetallic Fe-Ni catalyst simply mixed with HZSM-5 to enhance the stable and selective production of aromatics from syngas. The addition of Ni with Na substantially regulates iron carbide formation and suppresses carbon deposition, leading to increased selectivity to light alpha-olefins. The presence of Na weakens the Fe-Ni interaction, reduces electron transfer from Fe to Ni, and promotes the formation of lighter olefins, demonstrating the potential for developing stable and selective iron-based catalysts for the production of FT products.

Summary: Metal-support interactions in inverse catalysts prepared by adsorbing TEOS on Co3O4 can be manipulated by varying the solvent mixture. Deposition of TEOS on Co3O4 nanoparticles in n-hexane results in the formation of silica oligomers interacting strongly with cobalt(II,III)oxide after calcination at 573 K. Modification of Co3O4 nanoparticles with TEOS in a hydrolysing environment results in a stronger interaction due to the formation of surface cobalt silicate through hydrolysis.

Summary: This study reveals that the performance of iron-based catalysts can be modified by simply changing the percentage of Fe(II)/Fe(III) in the raw materials. The catalysts prepared by FeCl2·4H2O exhibit higher CO conversion, lower methane selectivity, and higher C-2-C-4 olefin-to-paraffin ratio, which can be mainly attributed to the higher Fe2+ content in the unreduced state.

Summary: The configuration between SiO2 and iron species plays a crucial role in determining the structure and performance of SiO2-promoted Fe-based Fischer-Tropsch synthesis catalysts. The construction of a SiO2 shell around iron species can inhibit iron oxides reduction and increase diffusion resistance, while physically separating iron species from SiO2 shell can effectively hinder sintering. Impregnated and precipitated Fe-Si catalysts experienced aggregation, and their performance correlated with the strength of Fe-SiO2 interaction.

Summary: ZIF-67 derived catalysts for Fischer-Tropsch synthesis have been studied extensively, and this work focuses on improving their activity and selectivity. Si/Al co-immobilized Co3O4@SixAly catalysts were prepared, and the effects of different Si/Al ratios on the metal-support interaction, acidity, and FTS performance were investigated. It was found that the catalyst with Si/Al ratio of 0.4 exhibited the best FTS performance, while the catalysts with Si/Al ratios of 3 and 2 showed higher iso-paraffin and olefin selectivity.

Summary: The CO2-to-aromatics process converts carbon dioxide (CO2) into valuable petrochemicals, specifically aromatics like benzene, toluene, and xylene, using metal/zeolite bifunctional catalytic systems. These aromatics are currently derived exclusively from fossil fuels and are used in various industrial applications. This process can help mitigate climate change by reducing greenhouse gas emissions and promoting a more sustainable and circular economy by reducing reliance on fossil fuels.

Summary: In this study, the photocatalytic oxidative coupling of methane (OCM) over transition-metal-loaded ZnO photocatalysts was systematically investigated. A 1 wt% Au/ZnO catalyst exhibited remarkable C-2-C-4 hydrocarbon production rate and selectivity under light irradiation. The selectivity towards C-C coupling products strongly depends on the metal type and its interaction with ZnO. The findings suggest that the d-sigma center can be a suitable descriptor for predicting product selectivity during OCM over metal/ZnO photocatalysts.

Summary: Transition-metal-based oxyhydroxides are efficient catalysts for biomass electrooxidation, but the identification of active sites is still challenging. In this study, cobalt oxyhydroxide (CoOOH) was used as an archetype, and the electrocatalytic glucose oxidation reaction (GOR) was used as a model reaction to track the dynamic transformation of the catalyst's electronic and atomic structure. Two types of reducible Co3+-oxo species were identified, including adsorbed hydroxyl on Co3+ ion (mu(1)-OH-Co3+) and di-Co3+-bridged lattice oxygen (mu(2)-O-Co3+). Theoretical calculations revealed that mu(1)-OH-Co3+ was responsible for oxygenation, while mu(2)-O-Co3+ mainly contributed to dehydrogenation, both playing crucial roles in the glucose-to-formate transformation. This work provides a framework for understanding the complex near-surface chemistry of metal oxyhydroxides in biomass electrorefining.

Summary: Researchers have developed a photothermal catalytic recycling system that can convert polyolefin plastics into liquid/waxy fuels. By using concentrated sunlight or xenon lamp irradiation, polyolefin plastics are heated, resulting in the hydrogenolysis of the C-C and C-H bonds in the polymer chains, leading to the complete conversion of waste polyolefins into valuable liquid fuels. This work demonstrates a simple and efficient strategy for recycling waste polyolefin plastics using abundant solar energy.
