A straightforward, single-stage hydrothermal approach was utilized to synthesize a unique CuO@rGO-MoS2 nanocomposite, featuring nest-mimicking architecture. It has highly efficient heterogeneous catalyzed property that can catalyze and activate the peroxymonosulfate (PMS) by means of radical (•OH, SO4•-, O2•-) nonradical (1O2) pathways generate ROS for rapid degradation organic dye rhodamine B (Rh.B). Graphene oxide, which high specific surface, serves as an excellent carrier achieves homogeneous dispersion main catalyst component gives series oxygen-containing functional groups become active centers route activation. Through experimental DFT calculation, it revealed MoS2 cocatalyst accelerated redox cycle Cu center during activation PMS via catalysis, further enhancing catalytic activity nanocomposites. And thus CuO@rGO-MoS2/PMS system with bird's-nest like structure Rh.B in short period, decomposition efficiency reaches 99% within 30 min duration reaction. Besides, this exhibits resistance environmental interference, demonstrating commendable across broad pH spectrum (pH 5-11) levels common interfering ions (Cl-, NO3-, SO42-, etc.). To conclude, study tried propose validate design idea based on selecting appropriate catalysts, cocatalysts, carriers achieve improved performance stability synthesized catalysts strategy have shown good performances real wastewater.

Molybdenum disulfide (MoS2)-based materials for piezocatalysis are unsatisfactory due to their low actual piezoelectric coefficient and poor electrical conductivity. Herein, 1T/3R phase MoS2 grown in situ on multiwalled carbon nanotubes (MWCNTs) was proposed. MoS2@MWCNTs exhibited the interwoven morphology of thin nanoflowers tubes, response 4.07 times higher than that via piezoresponse force microscopy (PFM) characterization. superior activity with a 91% degradation rate norfloxacin (NOR) after actually working 24 min (as rhodamine B, reached 100% within 18 min) by pulse-mode ultrasonic vibration-triggered piezocatalysis. It found removing pollutants attributed synergistic effect free radicals (•OH O2•–) nonfree radical (1O2, key role) pathways, together innergenerated-H2O2 promoting rate. 1O2 can be generated electron transfer energy pathways.
