Defect engineering of WO3 for selective photoelectrochemical glyoxal oxidation to glyoxylic acid

Key Points

• Glyoxal oxidation yielded glyoxylic acid significantly more efficiently with defect-engineered WO3.
• The highest conversion rate measured was 85%, with an improvement of about 30% compared to previous methods.
• Analysis using photoelectrochemical methods demonstrated significant advances in reaction efficiency and selectivity.
• This indicates the potential for using defect engineering to enhance reaction performance in sustainable chemistry.
