Summary: This study demonstrates the optimization of alpha-Fe2O3 nanoparticles modified by bimetallic oxyhydroxide NiFeOOH layers for photoelectrochemical hydrogen production. The optimized alpha-Fe2O3/NiFeOOH photoanode exhibits significantly enhanced photocurrent density and photon-to-current efficiency compared to bare alpha-Fe2O3 photoanodes. The synergistic effect of Ni2+ and Fe3+ in the NiFeOOH cocatalyst contributes to the improved efficiency of electron/hole separation and injection in the alpha-Fe2O3/NiFeOOH photoanode.

Summary: This article reviews the recent progress in developing self-supported heterostructured semiconductor nanoarrays as efficient photoanode catalysts for water oxidation in photoelectrochemical (PEC) water splitting. By controlling the growth conditions, heterojunction nanoarrays with different morphologies and semiconductor components can be fabricated, leading to improved light-absorption properties, stabilities, and PEC activities. The article discusses various synthetic methods and summarizes the reported heterojunction nanoarrays based on specific core semiconductor scaffolds, highlighting the synergies generated at the interface between the semiconductor components that enhance PEC water oxidation.

Summary: The performance of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) were enhanced by synthesizing the BiOI/graphitic carbon nitride nanotubes (g-C3N4 nanotubes) heterojunction. The stable heterojunction prevented rapid recombination between photoexcited electrons and holes, resulting in optimized electronic transmission pathway and faster surface reaction rates. Additionally, the composite exhibited outstanding OER and HER activities under illuminated conditions.

Summary: In this research, alpha-Fe2O3/Bi2S3 heterojunction photoelectrodes were successfully fabricated on FTO substrate using hydrothermal and solvothermal approaches to improve photoelectrochemical water splitting. The optimized alpha-Fe2O3/Bi2S3 photoanode demonstrated significantly higher photocurrent density compared to pristine alpha-Fe2O3, and showed enhanced photo catalytic performance under solar irradiation. The improvements were attributed to improved light-harvesting efficiency, enhanced conductivity, and effective charge separation at the alpha-Fe2O3/Bi2S3 interface.

Summary: This study demonstrates the size dependence of perovskite-type BaNbO2N particles on the photoelectrochemical (PEC) water splitting activity. The size of Ba5Nb4O15 particles, which are precursor oxides for BaNbO2N synthesis, was dependent on the calcination temperature. The reduction in size of oxynitride particles greatly improved the PEC water splitting activity.

Summary: In this study, molecular dynamics simulations were used to calculate the relationship between the dielectric constant and density of water at the mineral/electrolyte interface, and linear regression models were established to estimate the dielectric constant. The results showed that the oscillations of the dielectric constant at the interface are correlated with the density oscillations of water, and the accumulation of electrolyte ions causes a decrease in the dielectric constant. The computed dielectric properties can be used to estimate the capacitances in the surface complexation models.
