Gd2ZnMnO6/ZnO nanocomposites: Green sol-gel auto-combustion synthesis, characterization and photocatalytic degradation of different dye pollutants in water

Effects of ZnMgO Electron Transport Layer on the Performance of InP-Based Inverted Quantum Dot Light-Emitting Diodes

“…In addition, the optical band gap ( E g ) of ZnMgO and ZnO was determined using the absorption spectra [ 32 , 33 ]. The Tauc plot can be drawn by following the Equation (4) [ 28 , 32 , 33 , 34 ]: αhν = A(hν-E g ) n where α represents the absorption coefficient, hν is the photon energy that is calculated by the wavelength, A is a constant, and the value of n is 1/2 for the direct bandgap semiconductor of ZnMgO. The horizontal intercept of (αhν) 2 versus photon energy curves represents the E g .…”

Sol–gel auto combustion synthesis, characterization, and application of Tb2FeMnO6 nanostructures as an effective photocatalyst for the discoloration of organic dye contaminants in wastewater

“…The absorption bands at about 580 cm À1 are assigned to metal-oxygen bonds. 28 Band-gap is one of the parameters that can be changed and engineered according to particle size. 29,30 The value of this parameter is also signicant in performing the photocatalysis process.…”

Production, purification, and process optimization of intracellular pigment from novel psychrotolerant Paenibacillus sp. BPW19

“…To overcome these hurdles, complex treatment strategies involving nanomaterials have gained interest [ 11 , 12 ]. Nanostructures degrade dyes and particulate contaminants in an eco-friendly and cost-effective way by advanced oxidation processes such as photocatalysis, sonolysis, and Fenton reactions [ [13] , [14] , [15] , [16] ]. Lately, several nanoparticles [ 17 , 18 ], composites [ 19 ], nanocrystals [ 9 , 20 , 21 ], sorbents [ [22] , [23] , [24] ] have been developed and synthesized for the treatment of water contaminated by dyes and other pollutants.…”
