NiO-modified dioctahedral micas for photocatalytic hydrogen generation

Original language description

Due to the structural similarity between muscovite and illite, but their different behaviour when heated, their dehydroxylated forms after calcination at 600 °C were investigated as carriers for NiO particles. This work presents the first comparison of muscovite (Ms1) and illite as a muscovite-like structure (Ms2) in terms of their photocatalytic properties in photocatalytic hydrogen generation. Photocatalytic tests performed in a batch photoreactor, together with material characterization (XRD, IR, thermal analysis, and Raman spectroscopy), confirmed the excellent efficiency of illite, which was associated with its structural properties, higher TiO2 a Fe2O3 content, and larger specific surface area. The observed differences in photocatalytic behaviour indicate that the structural properties of muscovite and illite, the degree of dehydroxylation, and surface modification with methanol in methanol-water mixture significantly affect both the activity and stability of these 2:1 dioctahedral clay minerals. After the photocatalytic test, the shift of the C–O band in Raman spectroscopy was evaluated for the change in hydrogen bonds in MeOH50. Ms2 in the form of a matrix in the NiO/Ms2 composite improved the arrangement of MeOH50 layers and, at the same time, after 24 h of UV irradiation exhibited the highest photocatalytic activity and stability in photocatalytic hydrogen generation (469 μmol/gcat.)
