Abstract

The increasing depletion of fossil fuel resources promote the study of conversion of renewable biomass resources to valuable chemicals. Formic acid (FA) is regarded as desirable liquid hydrogen carrier. Glycolic acid (GA) has been extensively used for the treatment of photoaging and wrinkles. It is meaningful to explore novel catalysts for the selective oxidation of bio-platform molecules into FA and GA. Keggin-type polyoxometalates (POMs) were firstly explored as catalysts for the oxidation of 1,3-dihydroxyacetone (DHA), which is an important biomass-based platform molecule, to obtain GA and FA in the presence H₂O₂.The effect of catalyst structure and composition, and the reaction conditions on DHA oxidation were investigated. Among the chosen compounds, Cs₃PMo₁₂O₄₀ exhibited the best catalytic activity, with 86.4 % and 82.6 % yields of GA and FA, respectively. The five successive recycling experiments indicated that Cs₃PMo₁₂O₄₀ had good stability and reusability. The catalytic activity of Cs₃PMo₁₂O₄₀ was better than that of the other types of catalysts reported. This work give a clue for utilizing POMs as catalysts for the valorization of biomass derivatives to useful fine chemicals under mild conditions.

Keggin 磷钼酸铯从 1,3-二羟基丙酮高效共合成乙醇酸和甲酸

化石燃料资源的日益枯竭促进了将可再生生物质资源转化为有价值化学品的研究。甲酸（FA）被认为是理想的液态氢载体。乙醇酸（GA）已被广泛用于治疗光老化和皱纹。探索将生物平台分子选择性氧化为 FA 和 GA 的新型催化剂很有意义。研究了催化剂的结构和组成以及反应条件对 DHA 氧化的影响。在所选化合物中，Cs3PMo12O40 的催化活性最好，GA 和 FA 的产率分别为 86.4% 和 82.6%。连续五次回收实验表明，Cs3PMo12O40 具有良好的稳定性和可重复使用性。Cs3PMo12O40 的催化活性优于其他类型的催化剂。这项工作为利用 POMs 作为催化剂，在温和条件下将生物质衍生物转化为有用的精细化学品提供了线索。

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.
