“…However, g-C 3 N 4 has some shortcomings, such as a small visible light response range and rapid recombination of photogenerated electrons with holes, which limit its application in the field of photocatalysis. Qi et al [1] prepared g-C 3 N 4 /Bi 2 Fe 4 O 9 composite photocatalysts using a mechanical mixing method. After 240 min irradiation by 300 W xenon lamp, the degradation efficiency of RhB (10 mg/L) reached 87.59%.…”

Thermal polymerization prepared g-C3N4/HC composite with good visible light catalytic ability using corn stover and urea as raw materials. The structure of the g-C3N4/HC composite was characterized by XRD, and it was determined that the composite was composed of g-C3N4 and HC. The morphology of the g-C3N4/HC composite was characterized by SEM. g-C3N4 is dispersed in sheet form on HC tubes with a regular porous structure. The degradation efficiency of RhB by g-C3N4/HC reached 99.14% after 70 min irradiation by a 70 W metal halide lamp. The cyclic degradation experiments proved that g-C3N4/HC has good reusability. Compared with g-C3N4, the visible light absorption capacity of g-C3N4/HC is enhanced, and the electron-hole recombination rate is also reduced, which results in the higher photocatalytic capacity of g-C3N4/HC. The free radical trapping experiments confirmed that the hole free radical and the hydroxyl free radical are the primary active substances in the photodegradation reaction.

“…Defective sites, like oxygen vacancies were reported as possible reason. Heterojunctions take advantage of this band offsets by a cascade charge transfer in type II junctions, permitting the charge carriers to increase the lifetime [8]. Modified TiO2 nanoclusters with metal oxides of Sn, Pb, Zn, Cu have shown enhanced light activity [9,10].…”

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.
