The development of efficient catalysts to break down and convert woody biomass will be a paradigm shift in delivering the global target of sustainable economy and environment via the use of cheap, highly abundant, and renewable carbon resources. However, such development is extremely challenging due to the complexity of lignocellulose, and today most biomass is treated simply as waste. The solution lies in the design of multifunctional catalysts that can place effective control on substrate activation and product selectivity. This is, however, severely hindered by the lack of fundamental understanding of (i) the precise role of active sites, and (ii) the catalyst–substrate chemistry that underpins the catalytic activity. Moreover, active sites alone often cannot deliver the desired selectivity of products, and full understanding of the microenvironment of the active sites is urgently needed. Here, we review key recent advances in the study of reaction mechanisms of biomass conversion over emerging heterogeneous catalysts. These insights will inform the design of future catalytic systems showing improved activity and selectivity.

用于生物质转化的新兴多相催化剂:反应机理研究

开发用于分解和转化木质生物质的高效催化剂将是通过以下方式实现可持续经济和环境的全球目标的范式转变使用廉价、丰富且可再生的碳资源。然而,由于木质纤维素的复杂性,这种开发极具挑战性,如今大多数生物质都被简单地当作废物处理。解决方案在于设计多功能催化剂,可以有效控制底物活化和产物选择性。然而,由于缺乏对 (i) 活性位点的确切作用和 (ii) 支持催化活性的催化剂 - 底物化学的基本了解,这受到严重阻碍。此外,单独的活性位点往往无法提供所需的产品选择性,迫切需要全面了解活性位点的微环境。在这里,我们回顾了在新兴多相催化剂上生物质转化反应机制研究的最新进展。
