Tuning the adsorption behaviors of non-noble electrocatalysts to boost valorization of 5-hydroxymethylfurfural

Abstract

Nickel-based non-noble materials have been widely used as catalysts for a variety of electrosynthesis reactions due to their low-cost and tunable surface properties. However, few of them perform well for...

Electrocatalytic hydrogenation coupling oxidation using water in a highly efficient paired cell enabled by an oxygen defect-rich layered double hydroxide

“…62–64 To take full advantage of the water oxidation reaction at the anode during p -NP reduction at the cathode, we selected the oxidation of HMF to FDCA as the anode reaction in a paired electrochemical cell experiment. FDCA is an important pharmaceutical and chemical intermediate, 65–67 justifying the use of the conversion of HMF to FDCA as the anode reaction in our paired electrochemical cell.…”

Construction of NiCo-metaphosphate/hydroxide with synergistic heterostructure for sustainable biomass electro-oxidation

“…Meanwhile, HMF, HMFCA, and FFCA are detected only at the middle stage of the single-pass reaction, indicating that they are more likely intermediates. 12,56 In addition, another continuous reaction with 50 mM BHMF was conducted for comparison. HPLC analysis reveals a more remarkable formation of HMF during the BHMFOR, which may account for the slightly lower FE (87%) of FDCA (see Fig.…”

“…For electrocatalytic oxidation of biomass, the adsorption energy of substrate has been generally considered as an efficient descriptor of catalyst activity. 37,56,59,60 Specifically, too weak substrate adsorption is not favourable for triggering oxidation, especially when substrate concentration is very low. Unfortunately, the non-noble-metal-based catalysts usually suffer from the weak adsorption of the substrate, leading to unsatisfactory activity towards biomass oxidation.…”
