摘要:

羟甲基糠醛是呋喃类化合物, 具有价格低廉及来源广泛的优点, 可作为平台化合物用于制备其它高附加值产品. 传统的热催化氧化增值方法需要高温、 高压及贵金属催化剂, 造成经济效益的下降. 而电氧化方法不需要高温、 高压条件; 同时, 通过对电催化剂的合理设计, 非贵金属催化剂表面的羟甲基糠醛选择性转化已经得以实现, 从而避免使用大量贵金属. 因此, 通过电氧化方法对羟甲基糠醛平台化合物进行高附加值转化受到了广泛关注. 在羟甲基糠醛氧化的多种产物中, 羟基和醛基被全部氧化为羧基的产物——2,5-呋喃二甲酸, 被美国能源部列为“最具有价值的12种生物质衍生化学品”之一. 鉴于此, 本文介绍了羟甲基糠醛电氧化增值生产2,5-呋喃二甲酸的重要研究价值及相关非贵金属电催化剂的最新进展, 并对催化羟甲基糠醛电氧化反应的非贵金属催化剂的发展前景进行了展望.

Abstract:

Hydroxymethylfurfural is a furan compound, which is cheap and widely available, and can be used as a platform chemical to generate value-added products. Traditional thermo-catalytic methods always require high temperature, high pressure, and precious metal catalysts, leading to low economic benefits. By contrast, the electro-catalytic methods do not require harsh conditions including high temperature and high pressure; meanwhile, by using well-designed non-precious metal electrocatalysts, the selective conversion of hydroxymethylfurfural has been achieved, i.e., using precious metal catalysts is not necessary. Reasonably, the upgrading of hydroxymethylfurfural platform compounds via electro-oxidation methods has received extensive attention. Among the various products, 2,5-furandicarboxylic acid was crowned as one of the most valuable twelve biomass-derived chemicals by the department of energy of the united states. In this regard, this paper focuses on the electro-oxidation of hydroxymethyl furfural to generate 2,5-furandicarboxylic acid and review the research progress of non-noble metal catalysts. Finally, prospects for the development of non-precious metal catalysts for the electrooxidation of hydroxymethyl furfural are provided.
