Impurities of hazardous organic components are of growing concern for
water, which is considered the primary operating parameter used in photodegradation
investigations. Even in low quantities, the presence of hazardous chemicals in the water
system can pose threats to living organisms’ health and the environment. Traditional
remediation methods are inefficient in eliminating the toxicity of hazardous chemicals
containing wastewater effluents from the dye industry, the chemical industry, the
pharma industry, and the cosmetic industry. Nanocomposites (NCs) of titanium dioxide
(TiO2
) act as promising environmentally friendly photocatalysts for reducing water
pollution. This chapter is focused on the discussion of the intermediate products that
are produced during the photodegradation process using TiO2
NCs and determining the
impact of adding new elements on the TiO2
energy gap. The pace at which
photogenerated electron-hole pairs recombine, along with the suppression of the
anatase-to-rutile phase transition is also discussed. The benefit of conducting
comprehensive comparisons with a variety of photocatalytic reactions involving many
substrates; utilizing a solar simulator to clarify the effectiveness of doped materials is
also included in this chapter. The authors have tried to prove the idea of modulating the
photocatalytic process and anticipated the potential for using this process to accomplish
the utilization of wastewater effluent resources.
