How can photocatalytic water splitting be used to produce hydrogen?5 answersPhotocatalytic water splitting is a process that uses photocatalysts to convert solar energy into hydrogen. This process involves the use of materials such as ferroelectric semiconductor materials, tungsten oxides, and nanostructural photoelectrochemical catalysts. These materials have unique properties that allow for efficient water splitting. For example, single-domain ferroelectric photocatalysts like PbTiO3 can create polar surfaces and spatially separate charge carriers, enhancing the photocatalytic water splitting process. Tungsten oxides, such as sodium tungsten oxide bronze and tungsten trioxide nanosheets, can be used in a Z-scheme system to efficiently produce hydrogen and oxygen under visible light. Nanostructural photoelectrochemical catalysts, like CdS/CdSe-MoS2 and NiFe layered double hydroxide, can achieve high photocurrent densities and low overpotentials for the oxygen evolution reaction. These advancements in photocatalytic water splitting offer potential for the production of hydrogen as a clean and sustainable energy source.

How is hydrogenated TiO2 produced?4 answersHydrogenated TiO2 is produced through various methods such as direct-current reactive magnetron sputtering, radio frequency (RF) atmospheric pressure (AP) plasma, submerging an atmospheric-pressure plasma jet in a titanium precursor solution, and using a sealing-transfer reduction method at a relatively low temperature. These methods result in structural changes, introduction of Ti3+ species, improved visible light absorbance, and narrowed band gap, leading to enhanced photoactivity and microwave absorbing properties. The hydrogenation process involves the formation of TiH/TiOH bonds at the surface of the hydrogenated thin films, and the synthesis of H-TiO2 demonstrates improved visible light absorption and electrical conductivity due to a decreased work function and narrowed band gap. Additionally, the hydrogenated TiO2 exhibits greatly improved microwave absorption performance due to strong dielectric loss, excellent impedance matching, and attention loss.
