Abstract

The H₂ produced by the electrolysis process is classified as green energy. However, in conventional water electrolysis, H₂ is produced at the cathode and low-value O₂ is produced at the anode. In addition, the energy required to produce H₂ increases due to the sluggish kinetics of the oxygen evolution reaction (OER). By replacing water with biomass and its derivatives at the anode, H₂ can be produced at the cathode with less energy consumption, while value-added products such as formic acid, 2,5-furandicarboxylic acid (FDCA), 2-furoic acid, formate, acetate can be produced at the anode. Since the use of biomass-derived products instead of water in the electrolysis process is of strategic importance, this review focuses on the electrolysis of biomass and its derivatives. Through a comprehensive survey of numerous studies, the basic principles of the use of catalysts (electrocatalysts or redox mediators) in the electrolysis of biomass and derived products are explained. In conclusion, the causes of the current findings are comprehensively analyzed and important suggestions for solving these problems are given, opening new doors for future studies.

生物质和衍生原料电解产生 H2 和增值化学品的综合分析

电解过程产生的 H2 被归类为绿色能源。然而，在传统的水电解过程中，H2 在阴极产生，而低价值的 O2 则在阳极产生。此外，由于氧进化反应（OER）的动力学缓慢，产生 H2 所需的能量也会增加。通过在阳极用生物质及其衍生物代替水，可在阴极以较低的能耗产生 H2，同时可在阳极生产甲酸、2,5-呋喃二甲酸 (FDCA)、2-糠酸、甲酸盐、醋酸盐等高附加值产品。由于在电解过程中使用生物质衍生产品代替水具有重要的战略意义，因此本综述重点关注生物质及其衍生物的电解。通过对大量研究的全面考察，解释了在生物质及其衍生产品电解过程中使用催化剂（电催化剂或氧化还原介质）的基本原理。最后，全面分析了当前研究结果的原因，并提出了解决这些问题的重要建议，为今后的研究打开了新的大门。

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
