Over the past decade, metal-loaded hollow carbon nanostructures have been hailed as man-made nanoreactors (MHC nanoreactors) for extensive applications in dealing with energy and environmental issues due to their tailorable structure and electronic properties. Unlike conventional reports of hollow nanostructures with regard to synthetic methodologies or structural properties, a distinctive viewpoint on the microenvironment effects of MHC nanoreactors, i.e., metal–support interaction effect, reactant enrichment effect, molecular sieving effect, spatial compartmentation effect, and metal stabilization effect, is highlighted herein from this perspective. Furthermore, to emphasize the great potential of MHC nanoreactors in constructing a sustainable energy system to achieve a greener modern lifestyle, a review of the applications of MHC nanoreactors in the hydrogenation of typical biomass-derived molecules is presented. Additionally, prospects for broader biomass valorization applications of MHC nanoreactors, i.e., in situ hydrogen source-assisted hydrogenation, hydrogenation-involved cascade-type reactions, hydrogenation product distribution modulation, stability prolongation and recyclability enhancement, are forecasted. Toward the end of this paper, some feasible suggestions are further proposed for the enhancement of the catalytic reactivity, selectivity, stability, and sustainability of MHC nanoreactors in biomass hydrogenation, with a sincere expectation to contribute to the development of a highly efficient biomass refining system.

金属负载的空心碳纳米结构作为纳米反应器：微环境效应和生物质加氢应用的前景。

在过去的十年中，金属负载的中空碳纳米结构因其可定制的结构和电子特性而被人们誉为人造纳米反应器（MHC纳米反应器），可广泛用于处理能源和环境问题。与关于合成方法或结构特性的中空纳米结构的常规报道不同，关于MHC纳米反应器的微环境效应的独特观点，即金属-载体相互作用效应，反应物富集效应，分子筛效应，空间分隔效应和金属稳定化效应从这个角度在此突出显示。此外，为了强调MHC纳米反应器在构建可持续能源系统以实现绿色现代生活方式方面的巨大潜力，综述了MHC纳米反应器在典型的生物质衍生分子的氢化中的应用。此外，MHC纳米反应器在生物质增值方面的应用前景广阔，即预测了原位氢源辅助加氢，涉及加氢的级联反应，加氢产物分布的调节，稳定性的延长和可回收性的提高。在本文的最后，进一步提出了一些可行的建议，以提高生物质加氢中MHC纳米反应器的催化反应性，选择性，稳定性和可持续性，并真诚地希望为开发高效的生物质精制系统做出贡献。
