Metal oxides are reviewed as catalysts to transform H2O and CO2 to fuels the usage of solar power. For photo chemical conversion, TiO2 has been found to be the maximum stable and beneficial oxide cloth, but it's far currently restrained by means of its large band hole and a mismatch between its conduction band and the Red ox couples for water splitting and CO2 discount. A theoretical framework has been utilized to understand the simple thermodynamics and lively in photo chemical strength conversion systems. This is applied to model structures comprised of Ag2O and AgCl to examine why the previous reacts thermo chemically in air, at the same time as the latter reacts photo chemically. For thermo chemical conversion, zinc-, ceria-, and ferrite-based Redox cycles are examined and examples of high-temperature solar reactors driven with the aid of concentrated sun radiation are presented. For CO2 splitting, theoretical solar-to-fuel electricity conversion efficiencies may be as much as 26.8% for photo chemical systems, and may exceed 30% for thermochemical systems, supplied that realistic heat is recovered among the Redox steps. Abundance mixed with facile synthesis, smooth accessibility to unique oxidation states and polymorphs, sort of digital and magnetic right ties, low bio toxicity and natural elimination make of iron oxides a prototype of the appropriate useful material. In this studies news, we briefly describe some of the fundamentals and views of the use of iron oxides in bio medicine, electricity garage devices (anodes for lithium ion batteries), picture electrochemical water splitting and different sorts of catalysis.
