The design and development of high-performance photoanodes are the key to efficient photoelectrochemical (PEC) water splitting. Based on carrier transfer characteristics localized surface plasmon resonance effect noble metals, gold nanoparticles (AuNPs) have been used improve performance photoanodes. In this study, a novel composite BiVO4/Au/FeCoOx photoanode is constructed, quantitative analys...

In this study, the performance of ZnFe2O4-Fe2O3 heterostructure was tested for photocurrent generation via photoelectrochemical activity under irradiation. Additionally, effect photoanode on structural, optical properties, and charge kinetic behavior photoelectrode investigated. A combination nanostructures exhibited an enhanced ability light absorption compared to that pristine Fe2O3 ZnFe2O4 s...

Severe surface photocarrier recombination and poor electronic conductivity are the major factors behind sluggish photoelectrochemical water oxidation kinetics of ZnFe2O4 photoanode. Here, CeOx catalyst overlayer has been coupled with reduced nanorods (NRs) to reduce charge on photoanode significantly. The density functional theory (DFT) studies indicate that oxygen vacancy defect-rich construct...

In this communication, we report an innovative electrode design of 3D hierachical TiO2 urchin assembled with a hollow TiO2 spheres core and radial TiO2 nanorod shell prepared via a facile colloid template route combined with atomic layer deposition and a hydrothermal growth process. The periodically hierarchical TiO2 urchin exhibits excellent omnidirectional anti-reflectance properties in a wid...

Bridged ZnO nanorod arrays on V-grooved Si(100) substrate were used as the photoanode of a photoelectrochemical (PEC) cell for water splitting. Photolithography followed by reactive ion etching was employed to create a V-grooved structure on a Si substrate. ZnO nanorod arrays were grown via a hydrothermal method. The light trapping and PEC properties are greatly enhanced using the bridged ZnO n...

High quality ZnO nanowires arrays were homoepitaxial grown on Ga-doped ZnO single crystal (GZOSC), which have the advantages of high conductivity, high carrier mobility and high thermal stability. When it was employed as a photoanode in the DSSCs, the cell exhibited a 1.44% power-conversion efficiency under the illumination of one sun (AM 1.5G). The performance is superior to our ZnO nanowires/...

This thesis presents an integrated study of high efficiency photoanodes for water splitting using silicon and iron-oxide. The fundamental limitations of silicon to water splitting applications were overcome by an ultrathin iron-oxide film stack and a pH-adjusted electrochemical environment. It was experimentally demonstrated that this functional photoanode has very strong photoactivity exceedin...

A durable molecular photocathode driving CO2 reduction with over 1200 of turnover number was developed by electropolymerization Ru(ii) complexes. The cell a suitable photoanode enabled H2O oxidation no bias for 24 h.
