摘要/Abstract

摘要： 甲烷是重要的工业化学品原料,利用可再生能源将其高效、选择性地转化为高附加值化学品,对实现可持续发展具有重大意义。光热催化突破了传统热催化能耗高、光催化转化率低的技术瓶颈,能在相对温和的条件下实现甲烷的高效转化。本文在总结光热催化作用机制及甲烷转化反应装置的基础上,聚焦于光热催化体系的核心——催化材料。当前,光热催化体系中常用的催化材料主要分为金属氧化物、金属硫化物、有机-无机杂化材料和有机半导体材料四大类。其中,金属氧化物(如ZnO、TiO₂、CeO₂)因化学稳定性高、能带结构可调、环境友好及成本低廉等优势,成为甲烷转化领域的研究重点。基于此,本文从目标产物的角度出发,综述了光热催化甲烷转化制备含1个碳原子(C₁)、含2个及以上碳原子(C₂₊)及合成气等产物的催化材料最新研究进展。在催化材料性能提升策略方面,构筑缺陷结构、负载助催化材料及构建复合催化体系等是主流方法。针对当前机理研究尚不充分的问题,本文进一步总结了原位表征、载流子动力学表征以及理论模拟与机器学习等机理研究方法,包括瞬态吸收光谱和原位红外光谱等技术。未来,光热催化甲烷转化催化材料的研究仍将聚焦于通过材料设计实现产物产率、选择性与稳定性的协同提升。最后,本文对光热催化甲烷转化催化材料的未来发展方向提出了展望。

Abstract: Methane is an important raw material for industrial chemicals. Its efficient and selective conversion into high value-added chemicals via renewable energy is of great significance for achieving sustainable development. Photothermal catalysis breaks through the technical bottlenecks of high energy consumption in traditional thermal catalysis and low conversion rate in photocatalysis, enabling efficient conversion of methane under relatively mild conditions. On the basis of summarizing the mechanisms of photothermal catalysis and reaction devices for methane conversion, this paper focuses on catalytic materials, the core of photothermal catalytic systems. At present, the commonly used catalytic materials in photothermal catalytic systems are mainly divided into four categories: metal oxides, metal sulfides, organic-inorganic hybrid materials and organic semiconductor materials. Among them, metal oxides such as ZnO, TiO₂ and CeO₂ have become the research focus in the field of methane conversion owing to their advantages including high chemical stability, tunable band structure, environmental friendliness and low cost. On this basis, from the perspective of target products, this paper reviews the latest research progress of catalytic materials for photothermal catalytic conversion of methane to produce C₁ products (containing one carbon atom), C₂₊ products (containing two or more carbon atoms), syngas and other products. In terms of strategies to improve catalyst performance, constructing defective structures, loading co-catalytic materials and building composite catalytic systems are mainstream approaches. In view of the insufficient current research on reaction mechanisms, this paper further summarizes mechanism research methods including in-situ characterization, carrier kinetic characterization, theoretical simulation and machine learning, along with techniques such as transient absorption spectroscopy and in-situ infrared spectroscopy. In the future, research on catalytic materials for photothermally catalytic methane conversion will continue to focus on the synergistic improvement of product yield, selectivity and stability through material design. Finally, this paper puts forward prospects for the future development direction of catalytic materials for photothermally catalytic methane conversion.
