Valorization of xylose residues and crude glycerol for production of biopolyurethane foam

Waste and Biomass Valorization, 2023
Abstract Currently polyurethane (PU) products are heavily dependent on petroleum resources, highlighting an urgent need to develop new bio-based materials. This study aimed to develop a sustainable method of utilizing low-cost and renewable xylose residues (XR) and crude glycerol (CG) for the production of biopolyols.

Quantitative Photo‐Reforming of Biomass to CO Spurred by In Situ Protonation of Carbon Dioxide Radical Anions

Angewandte Chemie, EarlyView.
A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%
