“…It should be pointed out that from our simulations, the adsorption of dye occurs with ZrO 2 /MWCNT which form hydrogen bonds and weak van der Waals interactions (Verlicchi & Ghirardini 2019). The XRD and SEM characterization provides fundamental evidence of the high yield and purity of composite preparation (Dagar & Narula 2017;Assis et al 2019). UV-visible spectroscopy, the EDS test, and DLS are accurate, convenient, and rapid characterization tools for monitoring the adsorption and pollution removal process in aqueous systems (Kassem et al 2019;Higashiwaki & Fujita 2020;Kharlamova & Eder 2020).…”

Photocatalytic degradation of the dyes was deliberated by altering the catalyst and dye concentrations. The Zirconium oxide/Multiwall carbon nanotube (ZrO2/MWCNT) catalyst was facilely synthesized by a hydrothermal synthesis method. The nanocomposite ZrO2/MWCNT was formed in hydrothermal condition 95 °C of low growth temperature. The physico-chemical properties were successfully characterized using X-ray diffraction, (XRD) Scanning Electron Microscope (SEM), Energy dispersive Spectroscopy (EDS), Dynamic light scattering (DLS) analysis, X-ray photoelectron spectroscopy (XPS). The presence of Orbicular shaped ZrO2 nanocrystallines and Multiwall carbon nanotube was characterized by XRD pattern shows the presence of ZrO2 and MWCNT with the 2θ peaks at 19.62, 22.5 & 30.2. The thermal behavior of the ZrO2/MWCNT partials was also investigated by differential thermal analysis, and their vibrational bands were identified by infrared spectroscopy. The photo catalytic degradation of methylene blue in industrial wastewater was observed under UV light irradiation using the synthesized ZrO2/MWCNT as catalyst. The results revealed that the ZrO2/MWCNT nanoparticles exhibited high degeneration with COD and TOC reducing from 241 mg/L and 148.00 mg/L to 2.34 mg/L and 1.26 mg/L respectively with the efficiency of 90–94% over 25–60 min duration of UV irradiation time. In comparison with the pristine Zirconium Oxide and MWCNT, the composite ZrO2/MWCNT nanoparticles exhibited more efficient, the durable and stable photo-catalytic activity during experiments.
