Light-driven C1 Chemical Conversion with LDH-based Nanomaterials.

Energy serves as the fundamental assurance for human survival. Within the realm of energy, the C 1 chemical conversion stands out as a crucial process that has safeguarded the evolution of human society. With the introduction of the "double carbon" objective, the focus has shifted towards energy conservation, emission reduction, and environmental friendliness in the domain of C 1 catalytic conversion research. In recent times, the attention of researchers has been captivated by photo-driven C 1 chemical conversion, a method through which C 1 small molecules can be converted into diverse value-added products under ambient conditions. Layered double hydroxides (LDH) have emerged as key players in photo-driven C 1 chemical conversion, thanks to their unique 2D layered structure. This review delves into the most recent advancements in nano-state LDH-based materials for photo-driven C 1 chemical conversion. The exploration encompasses three key aspects: Layered double hydroxides (LDH) precursors functioning as catalysts, LDH derivatives serving as catalysts, and LDH playing the role of a catalyst carrier for photothermal catalytic CO 2 hydrogenation and CH 4 reforming & coupling. The review concludes by highlighting potential challenges that may be encountered in this field in the future. By scrutinizing and discussing the aforementioned research endeavors, this article aim to provide researchers with insights and inspiration for advancing the field of photo-driven C 1 chemistry.
