In this study, manganese selenide/copper oxide nanocomposites anchored on multi-walled carbon nanotubes (MnSe/CuO/MWCNTs) were fabricated with different ratios and their characteristic properties evaluated. Microscopic images show the decoration of CuO MnSe without changing morphology. UV–Vis analysis indicates that best optical MnSe/CuO/MWCNT nanomaterials via 2.06 eV as a band gap energy. The photocatalytic ability was evaluated by decomposition rhodamine B (RhB) (97.23%) malachite green (MG) (100.0%) under visible LED irradiation within 45 min. Furthermore, antibacterial activity prepared nanosamples investigated against Escherichia coli Staphylococcus aureus strains. results MnSe/CuO/MWCNTs can be used stronger agent.

Abstract Extensive research is being carried out on the degradation of water pollutants using various strategies to overcome global crisis. In present study, xerogels as a better alternative utilized metal oxides for photocatalytic toxic such dyes. Xerogels polyaniline (PANI) and polypyrrole (PPy) are synthesized phytic acid dopant well cross‐linker in weight ratios 1:1, 1:2, 2:1 via simple chemical oxidative polymerization. The analyzed their spectral, morphological, thermal, optical properties FTIR, UV–vis, XRD, SEM, TGA techniques. also tested activity against textile dyes – Methylene Blue (MB), Alizarin Red S, (ARS), Rhodamine B (RhB), Methyl Orange (MO). Among all composite xerogels, PANI/PPy‐2/1 showed excellent efficiency 91% MB dye, 88% RhB 96% ARS 92% MO dye respectively. PANI/PPy than pristine counterparts. fragments degraded examined LCMS technique tentative mechanism proposed.

The dual Z-scheme heterojunction CuBi2O4/Bi2Sn2O7/Sn3O4(CBS) was successfully constructed through in situ growth methods, and its photocatalytic performance evaluated via degradation of tetracycline hydrochloride under visible light. Out all samples, CBS-2 exhibited the highest activity, with an apparent rate constant 2.34, 20.16, 44.17 times that Bi2Sn2O7, CuBi2O4, Sn3O4, respectively. Even after four cycles, efficiency remained above 85%. improvement can be attributed to construction heterojunction, which effectively promotes separation migration photogenerated carriers. possible mechanism CBS deduced based on theory free radical capture energy band.
