Abstract

Exciting opportunities in biomass catalytic conversion have spurred extensive research and development into the chemical utilization of 5-hydroxymethylfurfural (HMF) and its derivatives. In this study, we achieved efficient base-free aerobic oxidation of HMF-derived tetrahydrofuran-2,5-dimethanol (THFDM) to tetrahydrofuran-2,5-dicarboxylic acid (THFDCA) on a Pt/OMS-2 catalyst, offering a potential alternative to petroleum-based 1,4-cyclohexanedicarboxylic acid (CHDA). Oxygen vacancies on the catalyst support played a crucial role in the oxidation process by enhancing surface lattice oxygen mobility and facilitating the oxidation of THFDM via the Mars-van Krevelen (MvK) mechanism. This in-depth exploration of bio-based products presents a promising avenue for the production of high-value building blocks.

Pt/OMS-2上无碱有氧氧化合成四氢呋喃-2,5-二羧酸：一种生物基柔性二酸†

在生物质催化转化方面令人兴奋的机会刺激了对5-羟甲基糠醛（HMF）及其衍生物的化学利用的广泛研究和开发。在这项研究中，我们在Pt/OMS-2催化剂上实现了hmf衍生的四氢呋喃-2,5-二甲醇（THFDM）的高效无碱好氧氧化成四氢呋喃-2,5-二羧酸（THFDCA），为石油基1,4-环己二羧酸（CHDA）提供了潜在的替代品。催化剂载体上的氧空位在氧化过程中起着至关重要的作用，通过增强表面晶格氧迁移率，促进THFDM通过Mars-van Krevelen （MvK）机制氧化。这种对生物基产品的深入探索为生产高价值的建筑模块提供了一条有前途的途径。

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
