Abstract
The selective oxidation of 5‐hydroxymethylfurfural (HMF) into 2,5‐diformylfuran (DFF) represents a critical step in the sustainable synthesis of high‐value chemicals from renewable biomass. A significant challenge in achieving this transformation lies in developing an effective visible light‐driven heterogeneous photocatalytic method that excludes the use of dye‐based sensitizers. While solar energy presents an exceptionally promising renewable energy source for extensive future applications, its overall utilization remains suboptimal. To address these challenges, we introduce an innovative photo‐thermo‐catalyst system comprising octahedral Cu2O particles, which, when combined with lignosulfonate (LS)‐supported 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO), demonstrates decent catalytic performance for the selective oxidation of HMF into DFF under the illumination of a 400 nm light‐emitting diode light. This system achieves a remarkable 95% DFF yield at 60 °C under ambient oxygen conditions. This study successfully demonstrates the effective integration of a non‐noble metal photo‐thermo‐catalyst with a supported TEMPO system, which enables the efficient HMF‐to‐DFF transformation driven by visible light, eliminating the need for dye sensitizers in the process.
期刊介绍:
Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry.
The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
