Abstract
The efficient utilization of biomass resources and solar energy is necessary for next-generation sustainable carbon-neutral societies. Although cellulose is the most abundant biomass on Earth, its utilization as a carbon resource is hampered by its strongly stabilized polymer-bundled structure. In this study, a new photoredox cascade catalyst (PRCC) conversion system was developed by combining dual-dye-sensitized Pt-cocatalyst-loaded TiO₂ nanoparticle photocatalysts (DDSPs) and a 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation catalyst for the production of cellulose nanofibers and hydrogen from various cellulose substrates (powder, paper, sponge, and wood pellets) under blue light irradiation without the use of strong acids/bases. UV-vis absorption and emission spectroscopy revealed that ….
