“…Indeed, the catalytic performance slightly decreased as the recycle number increased. This was mainly caused by the exfoliation of the ADH and Rh complex on the electrode surface, which resulted in the impairment of active sites for both NADH regeneration and enzymatic reduction in the electrical double layer . Fortunately, after 10 cycles of operation, the recovered bioelectrode still maintained considerably high selectivity toward furfuryl alcohol production from furfural.…”

The electroenzymatic valorization of biomass derivatives into valuable biochemicals has a promising outlook. However, bottlenecks including poor electron transfer between the electrode surface and oxidoreductase, inefficient regeneration of cofactors, and high cost of enzymes and electron mediators hindered the realistic applications of the technique. Herein, to address the above technical barriers, a novel bio-electrocatalytic system that integrates the electrochemical NADH regeneration and enzymatic reaction was constructed, using an orderly assembled composite bioelectrode consisting of an outer immobilized enzyme layer and a sandwiched redox mediator rhodium complex layer. The as-prepared composite bioelectrode was further applied for the highly selective hydrogenation of furfural into furfural alcohol. Results indicated that the enzyme activity was significantly improved, while the furfural valorization was promoted by effective interfacial electron transition and co-factor regeneration on the composite bioelectrode. Considerable high furfural conversion (96.4%) can be achieved accompanied by a furfural alcohol selectivity of 90.0% at −1.2 V (vs Ag/AgCl). The novel composite bioelectrode also showed good stability and reusability. Up to 85.1% of the original furfural alcohol selectivity can be preserved after 10 times of recycling. This work presents a promising green alternative for the valorization of furfural, which also shows great potential extending to the valorization of other biomass compounds.

Photocatalysis transformation of renewable biomass-derived building blocks into value-added chemicals is an attractive strategy in response to the environmental issues caused by the use of unsustainable petrol-chemical routes. On this basis, photocatalytic selective oxidation of reduced monolignols into aldehydes has emerged as a hotspot to be investigated. Herein, using ammonia solution as nitrogen source, NÀ TiO 2 photocatalysts were prepared through a simple pyrolysis process. Under visible-light irradiation, the NÀ TiO 2 photocatalysts were applied for selective oxidation of vanillyl alcohol into vanillin in acetonitrile. Results suggested that after doping nitrogen into the basic TiO 2 , the NÀ TiO 2 photocatalysts exhibited a narrow band-gap that could broaden the light absorption range, inhibit the recombination of photogenerated carriers, and enhance the affinity to the substrate molecules. Consequently, the photocatalytic performances of the vanillyl alcohol can be extensively improved by the NÀ TiO 2 (N-400) photocatalyst. A selectivity of 60.37 % of vanillin and a conversion of 60.84 % of vanillyl alcohol can be realized under the optimized conditions. The mechanism for the improved photocatalysis performances of vanillyl alcohol by NÀ TiO 2 was further proposed by combining the experimental and simulated results, which inferred that h + was the decisive active species for the effective oxidation of vanillyl alcohol. The NÀ doped TiO 2 photocatalysts are also adequate to selective oxidation of other renewable bio-alcohols into aldehydes.

Increased absorption of visible light, low electron‐hole recombination, and fast electron transfer are the major objectives for highly effective photocatalysts in biocatalytic artificial photosynthetic systems. In this study, a polydopamine (PDA) layer containing electron mediator, [M], and NAD+ cofactor was assembled on the outer surface of ZnIn2S4 nanoflower, and the as‐prepared nanoparticle, ZnIn2S4/PDA@poly/[M]/NAD+, was used for photoenzymatic methanol production from CO2. Because of effective capturing of visible light, reduced distance of electron transfer, and elimination of electron‐holes recombination, a high NADH regeneration of 80.7±1.43 % could be obtained using the novel ZnIn2S4/PDA@poly/[M]/NAD+. In the artificial photosynthesis system, a maximum methanol production of 116.7±11.8 μm was obtained. The enzymes and nanoparticles in the hybrid bio‐photocatalysis system could be easily recovered using the ultrafiltration membrane at the bottom of the photoreactor. This is due to the successful immobilization of the small blocks including the electron mediator and cofactor on the surface of the photocatalyst. The ZnIn2S4/PDA@poly/[M]/NAD+ photocatalyst exhibited good stability and recyclability for methanol production. The novel concept presented in this study shows great promise for other sustainable chemical productions through artificial photoenzymatic catalysis.
