摘要: 碳化钼(MoCx)具有独特的类贵金属反应活性、较好的热稳定性及可放大性, 使其性能超越传统过渡金属, 成为逆水煤气变换(RWGS)反应的高效催化剂. 2024‒2025年的最新研究进展显示, 以前未被充分探索的α-MoC相表现出巨大的应用潜力, 具有高活性和高CO选择性, 且碳化物动态参与到二氧化碳活化过程中. 原位机理研究和物相-活性的构性关系等些研究进展表明, MoCx可用作RWGS和下游二氧化碳稳定化利用的转换平台. 然而, 目前还存在一些关键问题有待解决, 如表面碳空位的确切作用、MoCx在动态RWGS条件下的长期稳定性、合成方法的可放大性, 以及在工业应用中的耐久性等. 本文集中综述了最近进展, 同时概述了将MoCx催化剂用于循环碳技术和工业二氧化碳利用所面临的当前挑战和未来研究机会.

Abstract: Molybdenum carbides (MoCx) are rapidly emerging as efficient catalysts for the reverse water-gas shift (RWGS) reaction, outperforming conventional transition metals with their unique blend of noble-metal-like reactivity, exceptional thermal stability, and scalability. Recent advances in 2024‒2025 have unlocked the excellent potential of the previously underexplored α-MoC phase, revealing unprecedented activity, robust CO selectivity, and dynamic carbidic carbon participation in CO2 activation. These advances, alongside in situ mechanistic insights and phase-activity correlations, make a compelling case for MoCx as a transformative platform for RWGS and downstream CO2 valorization. Despite these advances, critical questions remain regarding the precise role of surface carbon vacancies, the long-term stability of MoCx under dynamic RWGS conditions, the scalability of synthesis methods, and the durability for industrial deployment. This perspective provides the first focused synthesis of recent developments, while outlining current challenges and future research opportunities needed to position MoCx catalysts at the forefront of circular carbon technologies and industrial CO2 utilization.
