摘要

对化石燃料的广泛依赖使得利用5-羟甲基糠醛（HMF）等生物质衍生化合物可持续地生产有价值的产品成为可能。铜基材料由于其丰富度和可调节的氧化还原态而成为非均相电催化剂。在此，我们报道了作为双功能电催化剂的磷酸铜（Cu3P）量子点氧化和还原HMF分别为2,5-呋喃二羧酸和2,5-二（羟甲基）呋喃，它们作为平台化学品。对于HMFOR和HMFRR，我们分别在10和- 2 mA cm - 2电流密度下，在1 M KOH和pH 4 PBS中获得了57 %和45 %的法拉第效率。这项工作提出了以更低的能源成本，易于催化剂合成和环境条件取代传统水电解的阳极和阴极反应的范围。

Copper phosphide quantum dot: A bifunctional catalyst for electro- and photochemical transformation of biomass-derived 5-hydroxymethylfurfural

The extensive reliance on fossil fuel enables the harnessing of biomass-derived compounds, such as 5-Hydroxymethylfurfural (HMF), for the sustainable production of valuable products. Copper-based materials are gaining interest as heterogeneous electrocatalysts due to their abundance and tuneable redox states. Herein, we report copper phosphide (Cu₃P) quantum dot as a bifunctional electrocatalyst for oxidation and reduction of HMF into 2,5-Furandicarboxylic acid and 2,5-bis(hydroxymethyl)furan, respectively, which serve as the platform chemicals. We have achieved faradaic efficiency of 57 % in 1 M KOH and 45 % in pH 4 PBS at 10 and −2 mA cm⁻² current density for HMFOR and HMFRR, respectively. This work presents the scope of replacing anodic and cathodic reactions of conventional water electrolysis with less energy cost, easy catalyst synthesis, and ambient conditions.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
