Beschreibung

Anwendung

• Biosynthesis of catalysts for glycerol oxidation: A study demonstrates the biosynthesis of Au/CuO catalysts using Syringa oblata Lindl. leaf extract for efficient selective oxidation of glycerol to 1,3-dihydroxyacetone, highlighting a sustainable approach in catalyst production (Yuan et al., 2023).
• Photocatalytic hydrogen production: Research on biochars from olive stones as carbonaceous supports in Pt/TiO(2)-carbon photocatalysts explores their application in hydrogen production from aqueous glycerol photoreforming, offering insights into renewable energy sources and the role of dihydroxyacetone in sustainable technologies (Escamilla-Mejía et al., 2023).
