Electrocatalytic and thermocatalytic CO conversions provide promising routes to realize global carbon neutrality, and the development of corresponding advanced catalysts is important but challenging. Hollow-structured carbon (HSC) materials with striking features, including unique cavity structure, good permeability, large surface area, and readily functionalizable surface, are flexible platforms for designing high-performance catalysts. In this review, the topics range from the accurate design of HSC materials to specific electrocatalytic and thermocatalytic CO conversion applications, aiming to address the drawbacks of conventional catalysts, such as sluggish reaction kinetics, inadequate selectivity, and poor stability. Firstly, the synthetic methods of HSC, including the hard template route, soft template approach, and self-template strategy are summarized, with an evaluation of their characteristics and applicability. Subsequently, the functionalization strategies (nonmetal doping, metal single-atom anchoring, and metal nanoparticle modification) for HSC are comprehensively discussed. Lastly, the recent achievements of intriguing HSC-based materials in electrocatalytic and thermocatalytic CO conversion applications are presented, with a particular focus on revealing the relationship between catalyst structure and activity. We anticipate that the review can provide some ideas for designing highly active and durable catalytic systems for CO valorization and beyond.
电催化和热催化CO转化为实现全球碳中和提供了有前景的途径，开发相应的先进催化剂很重要但具有挑战性。具有独特腔结构、良好渗透性、大表面积和易于功能化表面等显著特征的中空结构碳（HSC）材料，是设计高性能催化剂的灵活平台。在本综述中，主题涵盖从HSC材料的精确设计到特定的电催化和热催化CO转化应用，旨在解决传统催化剂的缺点，如反应动力学迟缓、选择性不足和稳定性差。首先，总结了HSC的合成方法，包括硬模板法、软模板法和自模板策略，并对其特点和适用性进行了评估。随后，全面讨论了HSC的功能化策略（非金属掺杂、金属单原子锚定和金属纳米颗粒修饰）。最后，介绍了基于HSC的材料在电催化和热催化CO转化应用中的最新成果，特别着重于揭示催化剂结构与活性之间的关系。我们期望该综述能为设计用于CO增值及其他领域的高活性和耐用催化系统提供一些思路。
