Catalytic transfer hydrogenolysis, using liquid H-donors in the absence of pressurized H2 under mild temperatures, is regarded as the most important technology to substitute traditional hydrogenation processes in industry. Despite decade development with several breakthroughs in catalyst design, the reaction mechanism involved in H2 generation and subsequent hydrogenolysis reactions is still under debate. In this review, transfer hydrogenolysis of glycerol, as a representative example, on metallic catalysts is revised critically with respect to surface reaction mechanism and catalyst design. The detailed reaction pathways for propanol, methanol, formic acid and ethanol for H2 generation have been discussed systematically. In particular, reaction mechanism for catalytic C−H cleavage, H spillover/transfer and C−O cleavage reaction steps will be critically revised with experimental and theoretical results in literature. Insights into reaction pathways, mechanism and H2 transfer efficiency and structure-performance relation for Pd, Cu and Ni catalysts will be provided for future development of catalyst manufacture and process development. The outcome of this work is useful for successful implementation of bio-refinery.

甘油在多相催化剂上的催化转移氢解：机理研究的简短回顾
在温和的温度下，在没有加压 H 2的情况下使用液态氢供体的催化转移氢解被认为是替代工业中传统加氢工艺的最重要技术。尽管十年来在催化剂设计方面取得了多项突破，但 H 2生成和随后的氢解反应所涉及的反应机理仍在争论中。在这篇综述中，作为代表性例子的甘油转移氢解在金属催化剂上的表面反应机制和催化剂设计方面进行了批判性修改。丙醇、甲醇、甲酸和乙醇对 H 2的详细反应途径代有系统地讨论。特别是，催化 CH 裂解、H 溢出/转移和 CO 裂解反应步骤的反应机制将根据文献中的实验和理论结果进行严格修订。深入了解 Pd、Cu 和 Ni 催化剂的反应途径、机理和 H 2转移效率以及结构-性能关系，将为催化剂制造和工艺开发的未来发展提供参考。这项工作的成果有助于成功实施生物精炼。
