- W3036640719 abstract "Efficient PANI sensitized TiO2 based photocatalytic nanocomposites have been engineered to degrade strong organic dye like methylene blue (MB) under exposure to UV light. Hydrothermal process was adopted for the synthesis of TiO2 nanoparticles which were subsequently sensitized with a narrow band gap PANI via ex‒situ chemical oxidative polymerization. Here, PANI acts as a phototsensitizer which absorbs light in the UV–vis-NIR spectral region. Formation of the p-n junction heterostructure of PANI-TiO2 suppresses electron-hole recombination probability and enhances the separation of photogenerated charge carriers. Hydroxyl radicals present on the surface are evidenced for the formation mechanism of the nanocomposites which take part in photocatalysis reaction process as an active oxidizing agent. XRD confirms existence of anatase phase of TiO2 in nanocomposite samples. Increase of band gap energy with the increase in TiO2 content shifts the absorption spectra from visible to UV region. The first order and second order rate kinetics are determined from the Langmuir-Hinshelwood model. Experimental results demonstrate that 0.6 M PANI-TiO2 nanocomposite sample shows the highest kinetic rate and dye degradation efficiency. The efficiency is nearly 2.5 times higher than the pristine PANI and 3.1 times than pristine TiO2. Thus the synthesized nanocomposite is an economical and promising photocatalytic material for photodegradation of toxic organic methylene blue in water." @default.
