Abstract

A feasible scheme for the aerobic oxidation of 5-hydroxymethylfurfural (HMF) to FDCA without the addition of any soluble base is proposed. The nano catalysts were prepared by loading the common non-precious metal cobalt with the emerging acid-base mineral hydroxyapatite, and sodium hypochlorite (Sodium hypochlorite) and water were used as the oxidant and solvent, respectively, to produce FDCA with a yield of 73.7 % under alkali-free, ambient temperature and pressure (30 °C, air pressure) conditions for only 1 h. The main reaction parameters, such as the loading amount of Co/HAP, the content of sodium hypochlorite, the reaction temperature, and the reaction time, were systematically investigated. Main reaction parameters. From the preparation of catalyst to the catalytic conversion of HMF, the principle of green chemistry was fully adhered to, and the activity of the catalyst remained stable after the secondary activation, which successfully realized the catalytic conversion of HMF without adding extra alkali and with low energy consumption.

本文提出了一种无需添加任何可溶性碱即可将 5-羟甲基糠醛（HMF）有氧氧化为 FDCA 的可行方案。通过将常见的非贵金属钴负载到新兴的酸碱矿物羟基磷灰石中制备出纳米催化剂，并分别使用次氯酸钠（Sodium hypochlorite）和水作为氧化剂和溶剂，在无碱、常温、常压条件下生成 FDCA，产率为 73.系统研究了 Co/HAP 的负载量、次氯酸钠的含量、反应温度和反应时间等主要反应参数。主要反应参数。从催化剂的制备到 HMF 的催化转化，充分遵循了绿色化学的原则，催化剂在二次活化后活性保持稳定，成功实现了 HMF 的催化转化，且无需额外添加碱，能耗低。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
