Summary: Introducing promoters to cobalt-based catalysts can efficiently adjust their performance in converting syngas into long-chain hydrocarbons. In this work, CoMn@C composites were synthesized by carbonizing bimetal-organic frameworks. The incorporation of Mn significantly inhibits the production of CH4 and C2-C4 paraffin, while boosting light olefin and C5+ production in Fischer-Tropsch synthesis. The catalytic activity peaks at 2Co1Mn@C due to the abundance of Co-Mn interfaces.

Summary: Constructing hierarchically structured FeMnK@H-S-1(x) catalysts can enhance light olefins selectivity in Fischer-Tropsch synthesis, with the hierarchy factor playing a key role in promoting light olefins formation. Maximizing the hierarchy factor benefits the coordination of shape selective function and transport efficiency, leading to boosted light olefins selectivity on the synthesized catalysts. Additionally, moderate H-2 activation capacity and suppressed olefins secondary reactions also contribute to the enhanced light olefins selectivity.

Summary: In this study, Fe3O4 bulk catalysts assembled from nanoparticles were synthesized to investigate the size effect of Fe phase. The results show that when the particle size is smaller than 10 nm, the catalysts exhibit similar catalytic activity, while beyond 10 nm, the activity decreases significantly. Particularly, Fe3O4 with a nanoparticle size of 9.9 nm shows the highest activity, selectivity and ratio. Smaller particles contribute to C5+ formation while inhibiting CH4 selectivity.

Summary: In this research, the SEMK modelling approach was used to investigate the impact of catalyst descriptors on the yield of light olefins, identifying a promising catalyst with specific Q(H), Q(C), and Q(O) values that resulted in a high yield of light olefins. The combined effect of the three catalyst descriptors on conversion was observed, while the selectivity to light olefins was found to be less sensitive to Q(O). These effects were rationalized in terms of relative surface coverages of different species, leading to variations in dominant reaction pathways and product yield.

Summary: The activation of water molecules in thermal catalysis typically requires high temperatures, which poses a challenge for catalyst development in the low-temperature water-gas shift reaction (WGSR). Plasmonic photocatalysis provides a solution by activating water at low temperatures through the generation of light-induced hot electrons. In this study, a layered double hydroxide-derived copper catalyst (LD-Cu) was developed for efficient low-temperature photo-driven WGSR.

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: Enormous advances have been made in photothermal catalysis, but temperature assessment remains controversial in most photothermal catalytic systems. We revealed the phenomenon of temperature determination bias in gas-solid photothermal catalytic systems, which has been overlooked in most cases. To avoid temperature bias interference, we developed a universal protocol for reliable temperature evaluation by optimizing the reaction system. This study presents a functional and credible practice for temperature detection and emphasizes the effects of temperature differences in gas-solid photothermal catalysis.

Summary: This study measured the actual reaction temperature of photothermal ammonia synthesis over carbon-supported Ru catalyst using Le Chatelier's principle, and found that the activation energy for photothermal catalysis was much lower than thermocatalysis. This was attributed to hot-electron injection reducing the energy barriers for N2 dissociation and intermediates hydrogenation, while also suppressing carbon support methanation. The catalyst exhibited outstanding operational stability over 1000 hours. This work provides new insights into the effects of hot electrons in ammonia synthesis and guides the design of high-performance photothermal catalysts.

Summary: Inspired by the enzyme nitrogenase, researchers have explored semiconductor photocatalytic nitrogen fixation because of its similar surface catalytic processes. In this study, a facile and efficient method was developed to regulate ZnO/ZnCr2O4 photocatalysts using ZnCr-layered double hydroxide (ZnCr-LDH) as precursors. By optimizing the composition ratio of Zn/Cr in ZnCr-LDH, enhanced nitrogen photofixation performance was achieved under ambient conditions. The improved photocatalytic activity was attributed to effective carrier separation efficiency due to the abundant composite interfaces. This work demonstrates a promising strategy for synthesizing nanocomposite photocatalysts for nitrogen photofixation and other challenging photocatalytic reactions.

Summary: Low-cost and high-performance ZnO Schottky photodetectors (PDs) were fabricated by introducing Ti3C2TX into ZnO films via a facile spin-coated method. The ZnO/Ti3C2TX/ZnO compound film showed significantly improved performance on photocurrent, responsivity, noise equivalent power (NEP), normalized detection rate (D *), and linear dynamic region (LDR) compared with the original ZnO device. The enhanced conductivity and light absorption of the ZnO film after Ti3C2TX modification contributed to the superior performance.
