This study successfully synthesized a novel catalyst of CoMn alloy-loaded MnO using a one-step wet-chemical method, which exhibited good selectivity for light olefins in photothermocatalytic FTS, along with low CO2 selectivity for effective use of carbon resources.
As a promoter, Mn is widely used in Fischer-Tropsch synthesis (FTS) such as in the form of MnO, but few studies have focused on the effect of CoMn alloy on catalytic performance of FTS. Herein, a catalyst of CoMn alloy-loaded MnO is synthesized by a one-step wet-chemical method. The metallic Mn is formed through a segregation process from MnO support, which is induced by Co that is decomposed from Co-contained precursor; then, the two metals form an alloy in the following growing process. In photothermocatalytic FTS, the optimized catalyst delivers good selectivity for light olefins (27.0% with the ratio of olefins to paraffins = 3.2); meanwhile, low CO2 selectivity (22.6%) ensures the effective use of carbon resources. Characterizations, including X-ray photoelectron spectroscopy, high-resolution transmission electron microscopy, and energy dispersive X-ray mapping, reveal that the catalysts comprise CoMn alloy on MnO support. The formed CoMn alloy is the key for promoting the generation of light olefins. This study demonstrates a novel catalyst of CoMn alloy-loaded MnO for the production of light olefins via CO hydrogenation, which attains a value-added solar-to-chemical energy conversion.

Jiaqi Zhao, Ya Bai, Zhenhua Li, Jinjia Liu, Wei Wang, Pu Wang, Bei Yang, Run Shi, Geoffrey I. N. Waterhouse, Xiao-Dong Wen, Qing Dai, Tierui Zhang

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.

Selective Photocatalytic Oxidative Coupling of Methane via Regulating Methyl Intermediates over Metal/ZnO Nanoparticles

Pu Wang, Run Shi, Yunxuan Zhao, Zhenhua Li, Jiaqing Zhao, Jiaqi Zhao, Geoffrey I. N. Waterhouse, Li-Zhu Wu, Tierui Zhang

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.

Minimizing Temperature Bias through Reliable Temperature Determination in Gas-Solid Photothermal Catalytic Reactions

Xuanang Bian, Yunxuan Zhao, Chao Zhou, Tierui Zhang

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.

Quantifying the Contribution of Hot Electrons in Photothermal Catalysis: A Case Study of Ammonia Synthesis over Carbon-supported Ru Catalyst

Xuanang Bian, Yunxuan Zhao, Geoffrey I. N. Waterhouse, Yingxuan Miao, Chao Zhou, Li-Zhu Wu, Tierui Zhang

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.

Junyu Gao, Fan Wu, Yunxuan Zhao, Xuanang Bian, Chao Zhou, Junwang Tang, Tierui Zhang

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.
