![]() ![]() A variety of feedstock can be used for hydrogen production, including fossil resources such as petroleum, natural gas, and coal and renewable resources such as biomass and water. Hydrogen is a type of clean fuel as its combustion in a fuel cell generates only water emission. Keywords: Sol-gel process core-shell structure photocatalysis hydrogen production glycerol reforming For the high active 2 catalyst, after activation of TiO 2 with solar light irradiation, the conduction band electrons can be transferred to CuO core through the heterojunction in the core-shell interfaces which led to CuO gradually reduced to Cu 2O, favoring the reduction of proton to release hydrogen. g −1h -1, which was 29.0, 24.8, 11.2 and 3.2 times greater than that obtained on TiO 2 P25, and 2 catalyst, respectively.The highest rate of hydrogen production obtained with the 2 catalyst was as high as 153.8 μmol ![]() The catalysts containing TiO 2 as a shell and CuO as core showed much higher activity compared with those formulated with and bared CuO or NiO nanoparticles. These catalysts were prepared by the combination of a modified sol-gel and a precipitation-deposition method using hydroxypropyl cellulose as structural linker and they were characterized by powder X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen physisorption isotherms techniques. Hydrogen production from the photocatalytic reforming of glycerol aqueous solution was performed on the 2, 2, and core-shell nanostructured catalysts under simulated solar light irradiation. ![]()
