Electrocatalytic biomass valorization coupled with hydrogen production provides an efficient and economical way to achieve a zero‐carbon economy. Ni‐based electrocatalysts are promising candidates due to their intrinsic redox capabilities, but the rational design of active Ni site coordination is still a huge challenge. Herein, the combined strategies of surface reconstruction and heteroatom doping are adopted to modify Ni3S2 pre‐catalysts and the obtained bimetallic catalyst exhibits superior electrocatalytic performance toward 5‐hydroxymethylfurfural (HMF) oxidation to 2,5‐furanedicarboxylic acid (FDCA). Specifically, the oxysulfide‐coordinated amorphous NiOOH (NiOOH‐SOx) active phase is in situ constructed following the anionic regulation mechanism, which endows numerous defects and unsaturated sites for anodic HMF oxidation. Cu heteroatom doping further modulates the electronic structure of active sites with abundant Lewis acidic sites, offering advanced capability for HMF adsorption. Several operando characterization techniques (in situ Raman, infrared, and electrochemical impedance spectroscopies) are performed to disclose the reaction pathway and structure‐activity‐potential relationship. Theoretical results further demonstrate that Cu doping and oxyanionic regulation effectively modulate the local coordination environment of Ni sites and correspondingly tailor the intermediate adsorption behavior and then promote the reaction kinetics. Moreover, a two‐electrode system is assembled to pair HMF oxidation with cathode hydrogen production, demonstrating better energy conversion efficiency.

The present work gives an overview of the approaches for green synthesis of 5-hydroxymethylfurfural (HMF) and 2,5 furan dicarboxylic acid (FDCA) focusing on reduction in the byproduct formation such as levulinic acid and humins. It was elucidated that the use of highly polar and aqueous solvents, high Brønsted acidity, high pH, reaction time, and temperature increases the levulinic acid formation in the reaction. In contrast, humin formation is increased by high basicity, temperature, and initial substrate concentration. Specific catalytic and solvent systems for minimizing the byproduct formation during HMF synthesis are also discussed along with options for use of microwave, ultrasound, and continuous processes. In terms of intensification, safety, and ease of scale-up, the use of ultrasound for HMF synthesis is promising; however, microreactors are currently a better choice for higher substrate concentration usage and higher yields. Effect of parameters like reaction time, temperature, oxidizing source, solvent, and base on FDCA synthesis is also analyzed. Depending on the reaction conditions and the reactor type, the optimum temperature typically should be between 80 and 160 °C, moderate bases, such as K2CO3 and KHCO3, are preferred to maintain a preferred pH of 7−11 and O2 is an ideal oxidizing agent. The reaction pathway for FDCA synthesis from HMF was also studied and the effect of the base and solvent elucidated. Finally, one-pot synthesis of FDCA from HMF and the strategies necessary to optimize the FDCA yield has been discussed. It was demonstrated that one-pot two-step FDCA synthesis from sugars provides enhanced FDCA yield, selectivity, and lower byproduct formation, compared to one-pot one-step synthesis.

Photocatalytic selective oxidation of 5‐hydroxymethylfurfural (HMF) coupled H2 production offers a promising approach to producing valuable chemicals. Herein, an efficient in situ topological transformation tactic is developed for producing porous O‐doped ZnIn2S4 nanosheets for HMF oxidation cooperative with H2 evolution. Aberration‐corrected high‐angle annular dark‐field scanning TEM images show that the hierarchical porous O‐ZIS‐120 possesses abundant atomic scale edge steps and lattice defects, which is beneficial for electron accumulation and molecule adsorption. The optimal catalyst (O‐ZIS‐120) exhibits remarkable performance with 2,5‐diformylfuran (DFF) yields of 1624 µmol h−1 g−1 and the selectivity of >97%, simultaneously with the H2 evolution rate of 1522 µmol h−1 g−1. Mechanistic investigations through theoretical calculations show that O in the O‐ZIS‐120 lattice can reduce the oxidation energy barrier of hydroxyl groups of HMF. In situ attenuated total reflection surface‐enhanced infrared absorption spectroscopy (ATR‐SEIRAS) results reveal that DFF* (C4H2(CHO)2O*) intermediate has a weak interaction with O‐ZIS‐120 and desorb as the final product. This study elucidates the topotactic structural transitions of 2D materials simultaneously with electronic structure modulation for efficient photocatalytic DFF production.
