Published: March 3, 2025

Abstract The excessive use of fossil fuels has significantly increased environmental stress, driving the need for green, sustainable biofuel alternatives. Innovations in photocatalysis (PC), electrocatalysis (EC), and their synergistic approaches, like photothermal catalysis (PTC), photo‐enzymatic (PENC), photoelectrocatalysis (PEC), offer advanced methods biomass conversion into biofuels, surpassing traditional limitations. However, comprehensive research on these processes is still lacking. This review aims to systematically analyze recent progress catalytic strategies biomass‐to‐biofuel conversion. It first describes characteristics, types, properties biofuels. Then, it explores fundamental mechanisms PC, EC, combined technologies. chemical pathways involved conversion—such as transesterification, esterification, hydrogenation, decarboxylation, bond cleavage, cyclization—are examined. Efficient catalyst design specific reactions factors influencing efficiency rates are also discussed. Additionally, this paper assesses impact economic benefits green technology production, offering a valuable reference energy application. addresses challenges deployment production suggests future directions, aiming provide scientific guidance technical support development vital field. In summary, underscores importance continued innovation promote solutions.

Influence of Modification of Cysteine Residues in the Carbohydrate-Binding Domain on Cellulase Activity: Achieving Enhanced Performance and pH-Sensitive Recovery

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

The conversion of cellulosic biomass into fermentable sugars represents a pivotal stage in the environmentally friendly and sustainable production clean fuels chemicals. In this paper, new strategy to enhance enzyme performance was proposed. This can achieve pH-sensitive recovery cellulase while improving catalytic activity stability enzyme. achieved by means chemical modification cysteine residue (−SH) carbohydrate-binding domain (CBD) with PEG-based modifier (Mal-PEG-FA). It shown that altered conformation cellulase, which significantly improved efficiency CBD enzyme, turn promoted particular, modified molecular weight 10 k demonstrated highest level activity, an increase 130.02% comparison native cellulase. Ultimately, effective aqueous phase system accomplished adjusting pH system. After five cycles, still maintained 81.0% its initial enzymatic activity. research is significant strategic importance for promotion efficient utilization.
