Abstract

In this study, we significantly improved the PEC performance of glycerol oxidation by introducing an amorphous NiOOH co-catalyst onto BiVO₄ photoanodes. The effects of the bias voltage and pH on the selectivity of glycerol conversion products were meticulously investigated. The research demonstrated that increasing the bias voltage promoted glycerol oxidation, with an optimal voltage of 0.7 V leading to a significant increase in both the glycerol conversion rate and DHA selectivity, reaching up to 68 %. Additionally, pH played a critical role in the selectivity of glycerol oxidation products, with neutral to slightly alkaline conditions (pH=8) being the most conducive for DHA production. This study provides a promising strategy for sustainable glycerol valorization and offers a comprehensive understanding of the factors influencing PEC glycerol oxidation on NiOOH/BiVO₄ photoanodes.

期刊介绍： Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
