Abstract

Direct hydrogenolysis of biomass-derived furfural to produce 1,5-pentanediol, an essential precursor for polyesters and polyurethanes, plays a significant role in biomass utilization. In this work, using the carbothermal shock strategy, 1.5PtCo1Ce1-CTS ternary metal oxides were successfully prepared, containing abundant oxygen vacancies (O_v) and Co²⁺ species that are favorable for hydrogen transfer and ring-opening of furan, thereby enhancing catalytic activity and 1,5-pentanediol selectivity. Under an optimized condition (170 °C, 3 MPa of H₂, 4 h), the 1.5PtCo1Ce1-CTS catalyst achieved furfural conversion at 99.3% and 1,5-pentanediol selectivity at 59.2%. During recycling tests, the 1.5PtCo1Ce1-CTS catalyst exhibited high resistance to deactivation with a simple and rapid regeneration process. This work offers an alternative, versatile, and eco-friendly strategy for designing efficient heterogeneous catalysts for the hydrogenolysis of furfural into 1,5-pentanediol in the future.

糠醛选择性氢解制1,5-戊二醇PtCoCe三元氧化物催化剂的碳热冲击合成

生物质衍生的糠醛直接氢解生产1,5-戊二醇是聚酯和聚氨酯的重要前体，在生物质利用中起着重要的作用。本研究采用碳热冲击策略成功制备了1.5PtCo1Ce1-CTS三元金属氧化物，其含有丰富的氧空位（Ov）和有利于呋喃氢转移和开环的Co2+物质，从而提高了催化活性和1,5-戊二醇选择性。在优化条件（170℃，3 MPa H2, 4 h）下，1.5PtCo1Ce1-CTS催化剂的糠醛转化率为99.3%,1,5-戊二醇选择性为59.2%。在回收试验中，1.5PtCo1Ce1-CTS催化剂表现出较高的抗失活能力，再生过程简单快速。这项工作为未来设计糠醛氢解成1,5-戊二醇的高效多相催化剂提供了一种替代的、通用的和环保的策略。
