Harnessing MoO3/TiO2 Nanocomposites for Photocatalytic Reduction of [Cu(dien)(1-MeIm)Cl]Cl Complex: Paving the Way for Blue LED Application

Abstract

Abstract Over the past few decades, metal oxides have attracted significant research attention due to their wide-ranging applicability in nearly every field of study. In the present study, we focus on photochemical reactions promoted by using nanoscale MoO3, TiO2 and MoO3/TiO2 nanocomposite. The nanocomposite facilitated charge separation and elevated photo-destruction efficiency of [Cu(dien)(1-MeIm)Cl]Cl complex in a mixed solvent medium via an interlayer pathway. The synthesized complex and the nanomaterials were validated by various instrumental techniques. The lifetime of charge carriers (τ = 36 ns) is higher than bare materials proving its superior photo efficacy. Introduction of 40% acetonitrile (ACN:H2O) solvent gave a higher photoreduction rate constant for Cu(II) complex by MoO3/TiO2 (5.733 x 10-2 s-1) denoting the better photocatalytic nature of nanocomposite rather than the prepared bare nanomaterials. The findings from the study unambiguously reveal that even a small amount of surface incorporation significantly shifts the material for blue LED application. Thus, it paves the way for unleashing its diverse uses, comprehending its distinctive attributes and investigating its possibilities.
