Visible‐Light‐Controlled Oxidation of Glucose using Titania‐Supported Silver Photocatalysts

摘要: The visible-light-mediated photo-catalytic selective valorisation of glucose using TiO2-supported Ag nanoparticles is shown for the first time. optimisation catalyst composition, substrate-to-catalyst ratio and reaction medium proved that a near total suppression mineralisation pathway could be achieved with selectivity to partial oxidation products small-chain monosaccharides as high 98 %. primary were determined gluconic acid, arabinose, erythrose, glyceraldehyde formic acid. Under UVA light, organics decreases because production CO2 from mineralisation. A mechanism proposed based on an α-scission process combined Ruff degradation reaction, which explains presence products, smaller carbohydrates X-ray photoelectron spectroscopy, UV/Vis spectroscopy microscopy studies showed plasmonic 4 nm particles silver oxidised oxide over course recycling revealed this was not detrimental activity.
