Lithium niobate (LiNbO3) is an important ferroelectric material with a wide range of applications. In this work, the use of microwave radiation to improve the conditions of hydrothermal synthesis of pure nanocrystalline LiNbO3 was proposed. The struc

In this paper, we described the production of hydrogen using the water splitting method, in which catalytic reactions activate a photocatalyst in the presence of UVA/vis light. This catalyst breaks the water molecule, from which hydrogen is removed.

High surface area cerium oxide (CeO2-x) nanoparticles (S = 170 m2/g) were synthesized by the precipitation method with a narrow band gap (2.73 ± 0.03 eV). In comparison to typical band gap values for cerium oxide, it presents a red shift in the ligh
