Summary: By depositing CrOx on Mg-doped SrTiO3 semiconductors and introducing Ni/NiO catalyst nanoparticles, the AQYs for water splitting was increased from 10% to 26%. The deposition of CrOx significantly enhanced the stability of Ni/NiO nanoparticles and suppressed the dissolution of Ni ions, indicating a stabilizing effect. The study also revealed the formation of a Ni-Cr mixed metal oxide, which is highly effective in water reduction.

Summary: Optical monitoring and screening of photocatalytic batch reactions using cuvettes ex situ is time-consuming and does not allow analysis of species with low extinction coefficients. Hollow-core photonic crystal fibers (HC-PCFs) provide an innovative approach for in situ reaction detection using absorption spectroscopy, with high sensitivity for monitoring the analyte. They open the possibility of comprehensively studying photocatalysts to extract structure-activity relationships, which is unfeasible with similar reaction volume, time, and sensitivity in cuvettes.

Summary: Water splitting is a promising method to produce hydrogen as fuel, but it has lower production rate compared to common methods. This study focuses on the development of microreactors and photocatalysts to increase the production rate. Three optofluidic microreactors with different reaction chambers were fabricated and their performance was monitored using iodide/iodate as a redox mediator.

Summary: As nations transition towards low or net zero carbon economies due to global climate change, the need for practical alternative fuels is urgent. Hydrogen gas is considered one of the most desirable substitutes for traditional hydrocarbons, but obtaining "green" hydrogen from low or zero carbon footprint sources presents challenges. Research focuses on practical techniques for producing "green" hydrogen through photocatalytic or photoelectrocatalytic processes. However, the capability of this technology to produce hydrogen at scale has faced significant issues. This road map article explores various aspects of photocatalytic and photoelectrocatalytic hydrogen generation, including processes, materials science, reactor engineering, and biomass reforming applications.

Summary: Photocatalytic water splitting, an important process for producing clean energy, has seen successful advancements using transition metal oxides, metal sulfides/nitrides, and recently metal-organic frameworks (MOFs). MOFs, hybrid functional materials with customizable properties, have shown potential for degrading water to hydrogen and oxygen in a visible-light-driven manner. Benchmark achievements and limitations of using MOF photocatalysts for water splitting are discussed to guide future developments in this field.
