“…2,3 Titanium compounds are interesting due to their low-cost production, easy preparation, and excellent physical and chemical stabilities. 2 There are studies describing the various physical features of the Sr 2 TiO 4 material, such as superconductivity, magnetoresistance, extensive electrical and electrochemical characteristics, catalytic activity, and magnetic and optical properties. 1,4 Due to the ever-growing energy needs of our modern society (caused by a severe shortage of fossil fuels), it is necessary to search for clean and renewable energy resources, where one possible solution may be photocatalytic hydrogen production from water driven by solar insolation.…”
