Photocatalytic H2 evolution from aqueous solutions of oxygenated organic compounds in the presence of C3N4/reduced graphene oxide based photocatalysts

2022

Composites of C3N4/reduced graphene oxide have been used as a cheap and promising photocatalysts for triethanolamine and ethanol photo-reforming with H2 generation in aqueous solution. The rate of H2 production over the best performing photocatalysts reached 1,415 μmol·h-1·g-1 which increases up to 57,306 in the presence of 1% of Pt. The apparent quantum efficiency of the optimal material was 7 % by using both LED and natural sunlight irradiation

Facile preparation of CuBi2O4/TiO2 hetero-systems employed for simulated solar-light selective oxidation of 4-methoxybenzyl alcohol model compound

2023

The selective photocatalytic oxidation of organic substances is today considered one of the green techniques to synthesize important starting materials in different technological applications. This work reports an efficient, simple and cheap strategy for the synthesis of a new photocatalytic CuBi2O4-TiO2 (CBO/TiO2) heterosystem at room temperature. The prepared powders were characterized by X-ray diffraction (XRD), UV–Vis diffuse reflectance spectra (DRS), field-emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), and electrochemical measurements. The photocatalytic activity was evaluated by performing a probe reaction, namely the partial oxidation of 4-me…
