摘要
甲烷作为重要的气态化石能源,广泛存在于天然气中.利用非均相催化剂将甲烷转化为液体燃料是天然气全面经济开发的有效策略之一.目前催化剂普遍存在催化速率较慢、效率不高及催化剂难回收的问题.作为较新出现的晶态多孔材料,金属有机框架(MOFs)已被证明在各种功能化纳米材料的设计和合成中是有前途的非均相催化剂或载体/前体.本文系统地综述了基于MOFs的非均相催化剂将甲烷转化为高附加值化学品的最新进展.重点主要放在催化剂设计、催化反应性和反应机理上.此外,讨论了MOFs催化剂在甲烷转化中的主要挑战和进一步的发展方向.
Methane is one kind of important gaseous fossil fuel that widely exists in the natural gas. Conversion of methane to liquid fuel by heterogeneous catalysts is one of the effective strategies for the comprehensive economic development of natural gas. However, traditional homogeneous catalysts still suffer from low reaction rate, low efficiency and difficult recycling. Metal-organic frameworks(MOFs), as relatively new emerging crystalline porous materials, have shown to be promising heterogeneous catalysts or supports/precursors in the design and synthesis of various functional nanomaterials. In this review, the recent advances in MOFs-based heterogeneous catalysts for transforming methane into high value-added chemicals were reviewed systematically. Emphasis was mainly placed on the catalyst design, catalytic reactivity and reaction mechanism. Additionally, major challenges and further development for MOFs catalysts in the conversion of methane were discussed.
