Visible/solar light active photocatalysts for organic effluent treatment: Fundaments, mechanisms and parametric review

2017 International Journal

Intensive research work is being undertaken globally to effectively use the process of photo catalysis for the degradation of organic pollutants from industrial effluents. For the same,TiO2 has been extensively explored, which however,has a limitation of being able to utilize the UV spectrum-only, due to its high band gap property. Since a substantial percentage of the solar spectrum is visible light,it is imperative that for an effective and versatile utilization of the incident solar energy, visible light active photo catalysts, having are natively smaller band gap are developed.Smaller band gap,however,of ten results in rapid recombination and conversion of photonic enervation-usable heat.This art icleisa review of the sciencebehindtheperformanceofvisible/ solar lightactivephotocatalysts.The first partincludesthefundamentalsofphotocatalysis,including thermodynamics, reactionkineticsandrecombination.Thesecondpartreviewsthevisible/solarlightactive photocatalytic materialsaswellasthesignificant researchefforts madesofarintheexplorationofpossible mechanisms ofphotoexcitationandremediesforminimizationofrecombination.Finally,anoperational overview isprovidedwhichishelpfulinassessingtheinfluence ofkeyparametersonthephotocatalyticactivity.
