Abstract

In CrO4-TiO2, nanocomposite material is prepared by simple hydrothermal technique and its morphological characteristic are evaluated using High Resolution Scanning Electron Microscope (HR-SEM) and High-Resolution Transmission Electron Microscopy (HR-TEM) respectively, whereas the detection of elements are done by EDX analysis. PL learning evaluates electron hole recombination in InCrO4 -TiO2, which is confirmed by lesser luminescence emission intensity. Also the catalyst reflectance in visible region is calculated by Ultraviolet visible spectrophotometry Diffuse Reflectance Spectroscopy (UV-vis DRS) analysis. Brunauer, Emmett and Teller (BET) analyses the surface area. Wattle extract scientifically known as Acacia mearnsii is a leather tanning agent made of polyphenolic compound. Degradation process of such extract is carried out in visible-light for two hours. Here the results indicate that InCrO4-TiO2 exhibits more photo-catalytic activity than TiO2. Furthermore •OH formation is confirmed by fluorescence intensity. First-order kinetics mechanism as well as the higher quantum yields is also determined further. Electrochemical study using Dye Sensitized Solar cell (DSSCs) and Cyclic Voltammetry (CV) analysis of the prepared nanomaterial is discussed in detail. The catalyst is found to be steady and reclaimable.
