Summary: A surface modification strategy is developed to sequentially deposit ultrathin CoOx overlayer and Ni single atoms on Ti-doped alpha-Fe2O3 nanorods. The collaboration of CoOx overlayer and Ni single atoms improves the photo-electrochemical performance for water splitting, with a photocurrent density over three times that of Ti:Fe2O3. The passivation effect of CoOx overlayer reduces surface carrier recombination, while the catalysis effect of Ni single atoms accelerates water oxidation kinetics.

Summary: In response to the global increase in energy demand, researchers have been investigating alternative green fuels to replace conventional fossil fuels. The demand for hydrogen is expected to grow by 4-5% in the next 5 years. Different production technologies are used to obtain high yields of hydrogen, with 96% currently produced by conventional methods and the remaining 4% produced by electrolysis of water. Photo-electrochemical (PEC) water splitting is a promising pathway for solar-to-hydrogen conversion, and recent advancements in photocatalysts have been highlighted in this article.

Summary: Silicon nanowires (SiNWs) were prepared via a two-step metal-assisted chemical etching (MACE) method using n-Si(100) for 15 and 30 minutes. The morphology, structure, and optical properties of the SiNWs were studied using SEM, XRD, and UV-vis absorption. A photoelectrochemical cell (PEC) was used to measure the properties of a photoanode device based on n-SiNWs for water splitting. The SiNWs prepared in 30 minutes exhibited a photocurrent density of 3.72 mA.cm(-2) and a photoconversion efficiency of 1.37% at 0.78 V.

Summary: Since 2015, breakthroughs in generating new MAX phases with double transition metals have allowed for the synthesis of unique MXenes with diverse chemistry and complex structures, which are rare in 2D families. MXene-semiconductor hybrids have shown efficacy as photocatalysts due to their unique interface features. For photocatalytic purposes, Schottky heterojunctions can facilitate faster charge separation and lower Schottky barriers. Photocatalysts using semiconductors are predicted to be the most important and popular new photocatalysts, especially for photocatalytic and photo electrochemical applications. This article discusses semiconductor-based nanocomposites supported by MXenes, such as photocatalytic water splitting. The challenges and opportunities in developing semiconductor-based photocatalysts using MXenes are also addressed. Researchers in related fields are encouraged to explore novel photocatalysts based on semiconductors.

Summary: Titanium oxide is commonly used as an effective catalyst for photo-electrochemical water splitting, but its wide bandgap limits the utilization of visible and near-infrared light. The photosensitization of titanium oxide with plasmonic nanostructures has been proposed as a solution. In this work, a plasmon-based titanium oxide photosensitization method using a gold grating is presented. The gold grating supports the excitation and propagation of surface plasmon polariton wave, resulting in the activation of titanium oxide. Experimental results demonstrate that this structure enables efficient photo-electrochemical water splitting and hydrogen production under near-infrared light irradiation.
