The direct conversion of methane to hydrogen and high-value hydrocarbons under mild conditions is an ideal, carbon-neutral method for utilizing natural gas resources. Compared with traditional high-temperature thermal catalytic methods, using clean light energy to activate inert C-H bonds in methane can not only significantly reduce the reaction temperature and avoid catalyst deactivation, but also surpass the limitations of thermodynamic equilibrium and provide new reaction pathways. This paper provides a comprehensive review of developments in the field of photocatalytic non-oxidative conversion of methane (PNOCM), while also highlighting our contributions, particularly focusing on catalyst design, product selectivity, and the underlying photophysical and chemical mechanisms. The challenges and potential solutions are also evaluated. The goal of this feature article is to establish a foundational understanding and stimulate further research in this emerging area.
在温和条件下将甲烷直接转化为氢气和高价值碳氢化合物是利用天然气资源的一种理想的、碳中和方法。与传统的高温热催化方法相比,利用清洁光能激活甲烷中惰性的C-H键不仅可以显著降低反应温度并避免催化剂失活,还能突破热力学平衡的限制并提供新的反应途径。本文全面综述了甲烷光催化非氧化转化(PNOCM)领域的进展,同时突出了我们的贡献,尤其侧重于催化剂设计、产物选择性以及潜在的光物理和化学机理。还评估了面临的挑战和潜在的解决方案。这篇专题文章的目的是建立对这一新兴领域的基本理解并激发进一步的研究。
