For applications involving water cleanup, metal oxide nanoparticles are exceptionally successful. They are useful for the adsorption and photocatalytic destruction of organic pollutants due to their distinctive qualities, which include their wide surface/volume area, high number of active sites, porous structure, stability, recovery, and low toxicity. Metal oxide nanomaterials have drawn a lot of attention from researchers in the past ten years because of their various production pathways, simplicity in surface modification, abundance, and inexpensive cost. A wide range of metal oxides, such as iron oxides, MgO, TiO2, ZnO, WO3, CuO, Cu2O, metal oxides composites, and graphene–metal oxides composites, with variable structural, crystalline, and morphological features, are reviewed, emphasizing the recent development, challenges, and opportunities for adsorptive removal and photocatalytic degradation of organic pollutants such as dyes, pesticides, phenolic compounds, and so on. In-depth study of the photocatalytic mechanism of metal oxides, their composites, and photocatalytically important characteristics is also covered in this paper. Metal oxides are particularly effective photocatalysts for the degradation of organic pollutants due to their high photodegradation efficiency, economically sound methods for producing photo-catalytic materials, and precise band-gap engineering. Due to their detrimental effects on human health, pesticides—one of the highly hazardous organic pollutants—play a significant part in environmental contamination. Depending on where they come from and who they are targeting, they are categorized in various ways. Researchers focusing on metal oxides and their composites for the adsorptive and photocatalytic degradation of pesticides would find the review to be a beneficial resource. Detailed information on many pesticides, difficulties associated with pesticides, environmental concentration, and the necessity of degradation has been presented.

Hydrogen peroxide is widely used in medical and industrial applications, and the rapid detection of low concentrations of its vapor is considered to be a major challenge. In this study, we have successfully implemented the fabrication of an MWCNTs/ Fe 2 O 3 :ZnO chemoresistive sensor for hydrogen peroxide vapor (HPV) detection using RF magnetron sputtering and electron-beam deposition methods. The material properties of the MWCNTs/ Fe 2 O 3 :ZnO structure were characterized in detail using scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) elementary analysis, and transmission electron microscopy (TEM). The HPV sensing performances of the sensors were investigated in the temperature range 25−250 °C with and without ultraviolet (UV) irradiation. Sensor response values ranged from 35 to 1043 and from 7.3 to 198 at operating temperatures of 100 °C (without UV irradiation) and 150 °C (with UV irradiation), respectively, in the HPV concentration range of 1.5−22 ppm. Therefore, the Fe 2 O 3 :ZnO material decorated with MWCNTs is a promising candidate for integration into real-life HPV detection systems.
