- Description
- In this work, an efficient wide solar light-driven photocatalyst based on solar UV-blind β-Ga2O3 quadrilateral nanorods (β-GOR) has been modified with cobalt phthalocyanine (CoPc). Guided by density functional theory (DFT) calculations and experimental results, H-bond strengthened interfacial connection was established to purchase wide range of solar radiations and applied as an efficient photocatalysts for H2 evolution from water. The optimized 3CoPc/β-GOR nanocomposite unveiled an unprecedented in the quantum efficiency (0.38%) at 660 nm excitation wavelength with outstanding structural stability compare to the pristine solar UV-blind β-GOR (0%). The much extended photoactivities are accredited to the formation of strong H-bond between CoPc and β-GOR, that accelerated charge transformation as confirmed from Bader charge/work function analysis, activation of O2, wide visible-light absorption, as well as joint DFT and experimental results. We believe that this system will also work for other metal phthalocyanines such as ZnPc, NiPc and HPc together with β-GOR towards next-generation efficient photocatalysts with wide-visible light response.
