dc.description.abstract | The design of photocatalysts that encourage the conversion of CO2 into useful chemicals has been a recent topic of interest, owing to the consequences of climate change. This study develops h-ZTO/MoSe2 hybrid photocatalysts with multiple heterojunctions using facile electrospinning followed by a solvothermal method. MoSe2 nanosheets are formed inside and outside the h-ZTO hollow nanofibers (NFs), increasing the number of accessible active sites and improving the light-scattering properties, which are fundamental for improved photocatalytic performance. A hybrid photocatalyst was obtained by adjusting the h-ZTO/MoSe2 ratio, which showed significantly higher photocatalytic activity than pure h-ZTO. The morphology, structural, phase composition, and functional characteristics of the synthesized photocatalysts were investigated using FE-SEM, TEM, XRD, XPS, PL, TR-PL, and PEC. The 10 wt% h-ZTO/MoSe2 hybrid photocatalyst demonstrated the effective photocatalytic transformation of CO2 into CO, H2, and CH4 with yielding rates of 140, 64, and 33 µmolg−1h−1, respectively. Furthermore, it exhibited the highest CO2 photoreduction selectivity of 93%. This extraordinary performance can be attributed to the uniform growth of the MoSe2 on the internal and external walls of the hollow nanofibers, which enhanced their light-scattering capabilities and provided abundant active sites for the activation and desorption of CO2 throughout the reaction. © 2023 Elsevier Ltd | - |
