Here we show a novel strategy for tailoring the synergistic electrical properties of metal@semiconductor hybrid nanocrystals (HNCs) based on cation exchange-enabled electronic doping.
In this review, we discuss the merits and major challenges of p-type binary and ternary Cu-based metal oxide photocathodes and present the latest research effort in modifying the materials towards high-performance photocathodes.
H2 generation via solar photoelectrochemical water-splitting by Cr2O3 was successfully realized by surface modification with TiO2 and the following Pt deposition.
A p-type Co–ZnFe2O4 film with a one-dimensional (1D) rod-like morphology is fabricated for the first time on fluorine-doped tin oxide (FTO) through a hydrothermal reaction and sintering treatment.
Co3O4 nanostructures with different morphologies are directly grown on an ITO substrate and Sb2S3 is loaded onto these to construct a Co3O4/Sb2S3 heterojunction, which is used as an all p-type photocathode for PEC water splitting for the first time.
A peculiar synthesis protocol is highlighted for p-type CuBi2O4 and its nanocomposite with CuO at 78 °C, which yields a highly crystalline and anisotropic morphology, and superior photoelectrochemical water splitting performance.
