An integrated tandem photoelectrochemical (PEC) cell, composed of a three-dimensional (3D) ZnO/CdS/NiFe layered double hydroxide (LDH) core/shell/hierarchical nanowire arrays (NWAs) photoanode and a [Formula: see text]-Cu2O photocathode, was designed for unassisted overall solar water splitting in this study. The optical and photoelectrochemical characteristics of ZnO-based photoanodes and Cu2O photocathode were investigated. The results show that ZnO/CdS/NiFe LDH nanostructures offer significantly enhanced performances with a photocurrent density reaching 5.8[Formula: see text]mA[Formula: see text][Formula: see text][Formula: see text]cm[Formula: see text] at 0.9[Formula: see text]V and an onset potential as early as 0.1[Formula: see text]V (versus RHE). The enhancement can be attributed to the existence of CdS nanoparticles (NPs) which boosts the light absorption in visible region and enhances charge separation. Moreover, the introduction of NiFe LDH nanoplates, with unique hierarchical mesoporous architecture, promotes electrochemical reactions by providing more active sites as co-catalyst. On the above basis, the ZnO/CdS/NiFe LDH–Cu2O two-electrode tandem cell system was established. At zero bias, the device shows a photocurrent density of 0.4[Formula: see text]mA[Formula: see text][Formula: see text][Formula: see text]cm[Formula: see text] along with the corresponding solar-to-hydrogen (STH) conversion efficiency reaching 0.50%. Our results indicate that the tandem PEC cells consisting of metal–oxide–semiconductor photoelectrodes based on Earth-abundant and low-cost materials hold promising application potential for overall solar water splitting.

ABSTRACTSolar water splitting can potentially play a significant role in the future, sustainable and carbon-neutral energy infrastructure - by generating hydrogen as a green fuel from renewable sources and liquid-fuels via carbon-dioxide reduction. Hydrogen has higher gravimetric energy-yield compared to most of the conventional fossil fuels, is storable and transportable on demand. With the prospective green hydrogen economy in mind, considerable efforts have been made in the quest for a stable and efficient photocatalyst/photoelectrode which can eventually lead towards the realization of large-scale hydrogen production system. This snapshot review provides a summary of the basic principles and challenges associated with unassisted overall water splitting, and highlights the recent technological advancements made on the device and system designs on lab-scale - to improve different performance metrics, i.e., efficiency, stability, scalability and large-scale prototypes with demonstrated potentials for future developments.
