Electrocatalysts are critically important for a secure energy future, as they facilitate the conversion between electrical and chemical energy. Molecular catalysts offer precise control of structure that enables understanding of structure-reactivity relationships, which can be difficult to achieve with heterogeneous catalysts. Molecular electrocatalysts can be immobilized on surfaces by covalent bonds or through non-covalent interactions. Advantages of surface immobilization include the need for less catalyst, avoidance of bimolecular decomposition pathways, and easier determination of catalyst lifetime. This Minireview highlights surface immobilization of molecular electrocatalysts for reduction of O , oxidation of H O, production of H , and reduction of CO .
电催化剂对于实现安全的能源未来至关重要，因为它们有助于电能和化学能之间的转换。分子催化剂能够精确控制结构，从而有助于理解结构与反应活性之间的关系，而异相催化剂则难以做到这一点。分子电催化剂可以通过共价键或非共价相互作用固定在表面上。表面固定的优点包括所需催化剂较少、避免双分子分解途径以及更易于确定催化剂寿命。本综述重点介绍了用于氧还原、过氧化氢氧化、析氢和一氧化碳还原的分子电催化剂的表面固定化。
