Heterojunction photocatalysts have gained much attraction in pollutant degradation applications due to their unique good adsorption and photocatalytic decomposition capacity more cycle durability. Tin oxide (SnO2) doped with copper (CuO) heterostructured photocatalyst was synthesized by a simple solution processes technique. X-ray diffraction fluorescence spectroscopy were used examine the structural properties of SnO2 - CuO heterostructure. Analyses FE-SEM TEM performed on samples determine surface morphology. The photodegradation property heterostructure studied using methylene blue (MB) model pollutant, where (90.3 % at 180 min) shown better than SnO2. Therefore, n-p-junction (SnO2 CuO) catalysis boosted MB detailed studies electron-hole pair recombination conducted n-p-junctions observe effect interface been published.

A wide range of nanoparticles have been produced for photocatalysis applications. Nonetheless, degrading organic dyes requires that are efficient and excellent. As a photocatalyst, pure manganese oxide (MnO2) was prepared via sol–gel method using silver (Ag) transition metal oxide. In addition to X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), the crystal structure elemental composition were analysed. According XRD data, MnO2 is highly has small crystallite size. The presence functional groups confirmed clarified Fourier-transform infrared spectra (FTIR). By irradiating doped photocatalysts with visible light, UV-vis, μ-Raman, surface areas determined. result, aqueous methylene blue (MB) solutions under light irradiation, Ag demonstrated high degradation efficiencies utilised establish heterogeneous dominance. this paper, we demonstrate photocatalytic efficiency oxides exclusively determined by particle size area nano-sized materials. Due their charge ratio different orientations, highest efficiency. Generally, resistant bacteria both Gram-positive Gram-negative types (B. sublittus Escherichia coli). There still need more research be performed on reducing toxicity so they can used as an effective alternative antibiotics disinfectants, particularly biomedical
