“…In recent years, transition metal nitrides have received widespread attention as intermetallic compounds for photocatalytic applications owing to their good electrical conductivity and narrow band gap [50] . In Liu's work, [51] Au nanoparticles were deposited onto the surface of InGaN nanorods (NRs) to significantly improve the photocatalytic efficiency. The SPR effect induced by Au nanoparticles promoted the separation of electron‐hole pairs while the nanorod structure of InGaN had a larger bulk surface area to capture more light.…”

As a promising technique to potentially address the energy crisis and environmental issues, photocatalysis has been reported widely to exhibit various outstanding behaviors in production of new fuels/chemicals and treatment of contaminants. The photocatalytic performance is extremely dependent on the used photocatalysts, so that the design and preparation of efficient photocatalysts are critically important for significantly improving the photocatalytic activity. Among various strategies, the hybridization of metal with semiconductors has recently been attracting more and more research interest owing to their expended spectral absorption, promoted transferring rate of charge carriers and Plasmon‐enhanced effect. In this minireview, the metal‐facilitated hybrid photocatalysts are overviewed comprehensively to first reveal unique functions of metals in improvement of photoactivity and summarize the emerging metal‐involved hybrid systems. Subsequently, the synthetic methods towards hybrid photocatalysts are introduced and their practical applications are emphasized in environmental remediation including degradation of organic pollutants, conversion of harmful gases, treatment of heavy metal ions and sterilization of bacteria. At the end, the challenges for industrializing these hybrid photocatalysts are discussed carefully and future development is suggested rationally.

“…However, the current density of a GaN-NW photoanode is theoretically limited to less than 10 mA/cm 2 because of the large interfacial charge-transfer resistance and fast recombination of photoinduced charge carriers largely due to upward bending of the energy-band at the GaN surface . Attempts to overcome the influence of the surface-trap states to improve the PEC-WS performance led to the passivation of the NW surface using noble metals, such as Au and IrO 2 . , For example, Liu et al reported an InGaN-nanorod photoanode decorated with Au nanoparticles with a current density of ∼8.7 mA/cm 2 . Chu et al reported an IrO 2 /InGaN-NW photoanode with a current density of ∼10.9 mA/cm 2 and an applied-bias photon-to-current conversion efficiency (ABPE) of 3.5% .…”

The photoelectrochemical water splitting (PEC-WS) performance of a photoanode consisting of GaN nanowires (NWs) is significantly improved using a Ti 3 C 2 -MXene coating as an intermediate layer to promote carrier transfer toward the electrolyte. The maximum current density and applied-bias photon-to-current efficiency of the photoanode comprising GaN NWs coated with Ti 3 C 2 -MXene (MGNWs) are measured to be 34.24 mA/cm 2 and 14.47% at 1.2 and 0.4 V versus a reversible hydrogen electrode (RHE), respectively. These values are much higher than those of the GaN-NW photoanode without Ti 3 C 2 -MXene (4.04 mA/cm 2 and 1.95%) and also markedly exceed those of previously reported photoanodes. After 8 days of PEC-WS, the current density was measured to be 31.07 mA/cm 2 , which corresponds to 97.58% of that measured immediately after the reaction started. Based on the time dependence of the current density, the hydrogen evolution rate over the reaction time is calculated to be 0.58 mmol/cm 2 •h. The results confirm that the PEC-WS performance of the optimized MGNW photoanode is superior to and more stable than those of previously reported photoanodes.

“…Jiang et al found that the maximum solar-to-hydrogen efficiency is 4.3% for Cu-doped TiO 2 –12CdS NWs photoanode. Recently, Wang et al studied the PEC water splitting enhancement by Au@Pt-modified ZnO-CdS heterojunctions with a photocurrent density as high as 4.23 mA/cm 2 at 1.23 V. However, the influence of plasmonic metal nanoparticles on InGaN-based heterojunction semiconductors for the PEC water splitting was seldom reported. − …”

In this study, a Ag/WO 3 /InGaN hybrid heterostructure was successfully developed by sputtering and molecular beam epitaxy techniques, to obtain unique Ag nanospheres adorned with cauliflower-like WO 3 nanostructure over the InGaN nanorods (NRs). Exploiting the localized surface plasmon resonance of Ag, the Ag/WO 3 /InGaN heterostructure exhibited superior photoabsorption ability in the visible region (400−700 nm) of the solar spectrum, with a surface plasmon resonance band centered around 440 nm. Comprehensive analysis through photoluminescence spectroscopy, photocurrent measurements, and electrochemical impedance spectroscopy revealed that the Ag/WO 3 /InGaN hybrid heterostructure significantly enhances the charge carrier separation and transfer kinetics leading to improved overall photoelectrochemical (PEC) performance. The photocurrent density of the Ag/WO 3 /InGaN photoanode is 1.17 mA/cm 2 , which is about 2.72 times higher than that of pure InGaN NRs under visible light irradiation. The photoanode exhibited excellent stability for about 12 h. From the study, it has been found that the maximum applied bias photon-to-current efficiency (ABPE) is ∼1.67% at the applied bias of 0.6 V. The improved PEC water splitting efficiency of the Ag/WO 3 /InGaN photoanode is attributed to the synergistic effects of localized surface plasmon resonance (LSPR), efficient charge carrier separation and transport, and the presence of a Schottky junction. Consequently, the plasmonic metal-assisted heterojunction-based semiconductor Ag/WO 3 /InGaN demonstrates immense potential for practical applications in photoelectrochemical water splitting.
