Optical bandgap of mn2o3
WebThe direct optical band gap energies of 2.80, 2.52, 2.75 and 2.90 eV for the films fabricated at 400, 450, 500 and 550 degrees C respectively were found. Photo-oxidation of water via Mn2O3-TiO2 thin films was carried out under simulated solar irradiation of AM 1.5 G (100 mW/cm(2)) in 0.5 M Na2SO4 using three-electrode photoelectrochemical cell. Weboptical band gap of rGO can be widened effectively to about 2.7eV from 1.15eV [3]. This is still below the bandgap limit for WBG material, which is about 3.5ev to 4.6 eV [4]. Chitosan (a partially N-deacetylated derivative of Chitin) is a polysaccharide consisting of D-glucosamine and N-acetyl-glucosamine units, connected via β-(1→4 ...
