甲醇氧化羰基化合成碳酸二甲酯(DMC)是煤炭清洁高效利用的重要技术路线。基于多孔炭负载纳米Cu催化剂良好的催化性能,从多孔炭形貌及孔结构、缺陷结构和助剂等对催化性能的影响出发进行了综述,重点探讨了多孔炭纳米Cu催化剂高分散性、高纯度和缺电子性质与DMC高效合成之间的构效关系。目前,多孔炭纳米Cu催化剂仍面临若干关键挑战:在合成方面,难以有效克服Cu颗粒的本征团聚与氧化倾向;在结构调控方面,缺乏对Cu位点缺电子程度的定量界定与优化阈值。此外,现有研究在催化剂长效稳定性评估与反应机理深入解析方面仍存在明显不足。面向未来,多孔炭纳米Cu催化剂的发展应聚焦于精准调控,如通过前驱体工程与价态源头控制,实现活性位点的理性构建,结合电子结构描述符建立定量化构效关系;进一步借助反应气氛构建动态自稳定机制,并通过理论与实验的深度融合系统阐明真实反应路径,最终实现催化剂的高效稳定运行。
The oxidative carbonylation of methanol to synthesize dimethyl carbonate (DMC) is an important technological route for the clean and efficient utilization of coal. Based on the excellent catalytic performance of nano-Cu catalysts supported on porous carbons
the effects of the morphologies and pore structures
defects and additives on the catalytic performance were reviewed. The structure-activity relationship between the high dispersion
high purity and electron-deficient property of nano-Cu catalysts and the efficient synthesis of DMC was mainly discussed. At present
the nano-Cu catalysts supported on porous carbons still face several key challenges: In terms of synthesis
it is difficult to effectively overcome the intrinsic agglomeration and oxidation tendency of Cu particles. In terms of structural regulation
there is a lack of quantitative definition and optimization threshold for the degree of electron deficiency of Cu sites. In addition
the existing research still has obvious deficiencies in the long-term stability assessment of catalysts and the in-depth analysis of reaction mechanisms. Looking to the future
the development of the nano-Cu catalysts supported on porous carbons should focus on precise regulation. For example
the rational construction of active sites can be achieved through precursor engineering and source control of valence states. And the quantitative structure-performance relationship can be established using electronic structure descriptors. Further
a dynamic self-stabilizing mechanism can be constructed in the reaction atmosphere
and the real reaction path should be systematically clarified through the deep integration of theory and experiment. Ultimately
the high efficiency and long-term stability of the catalysts can be achieved.
