Summary: Cellulose and hemicellulose are the main components of lignocellulosic biomass, and chemical derivatization can produce valuable C5 and C6 organic compounds, which are important for the development of sustainable chemical processes. However, the structural properties of cellulose, such as high crystallinity, abundant hydrogen bonding, and low solubility, limit the success of most depolymerization processes. Various chemical treatments, including acidic treatment and photocatalysis, have been developed to overcome these limitations. Photocatalysts, in particular, show great potential for efficient cellulose biomass conversion without the need for high temperatures.

Summary: In this study, a bimetallic catalyst of Au-Pt/Al2O3 was prepared for the production of high-value carboxylic acids from glycerol. The catalyst showed high conversion efficiency, but exhibited an induction period and deactivation during the long-term catalytic activity test using a liquid-phase flow reactor. The scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy characterization revealed that nanosized Au and Pt species were well dispersed on the catalyst support.
