Developing highly active and available, environmentally friendly, low-cost photocatalytic materials is one of the most popular topics in degradation systems. In present study, a series BiOCl/Sepiolite composite photocatalysts were prepared (in range 5%BiOCl/Sepiolite–30%BiOCl/Sepiolite). Their characterization was conducted using X-ray diffraction, diffuse reflectance spectroscopy, scanning electron microscopy, nitrogen physical physisorption at temperature liquid (77 K), attenuated total reflectance-Fourier transform infrared spectroscopy. Results showed that possess superior efficiency than parent for losartan, an antihypertensive agent, water, with sample only 10%wt. BiOCl shows highest performance.

The rapid growth in industrialization and population has resulted the generation permanence of a wide variety inorganic organic pollutants, posing potential risks to environment human health. degradation (either removal or reduction) sensing these pollutants from various environmental media (e.g., air, water, soil) are nowadays important problems worldwide. To address this issue, several nanotechnologies numerous nanostructured materials composites have been established for efficient remediation applications. This is ascribed their large surface area improved characteristics efficiency (like high reactive feature). current chapter reports such as filtration, photocatalysis, chemical reactions, absorption, adsorption, nanosensing, etc. It also offers an overview use environment. Novel materials, involving inorganic-based nanomaterials (NMs) zero-valent metal NMs, oxide-based silica-based NMs), carbon-based polymeric-based well nanocomposites were extensively reported discussed. These efficiently employed remediating halogenated herbicides, volatile compounds, chlorinated aromatic aliphatic hydrocarbons, pharmaceuticals, dyes, heavy metals, biological substances antibiotics, parasites, bacteria, viruses), gases (NOx, CO, SO2, etc.). Their efficiency, advantages, limitations compared Moreover, some directions future studies proposed.

Efficient, low-cost, and easily scalable wide-spectral-responsive TiO2 photocatalysts are still extremely desired in driving photocatalytic degradation toward practical applications. In this work, a modified with narrow band gap low valence (VB) (CC-OV-TiO2) was successfully synthesized based on facile sol–gel low-temperature carbonization process, which can be used for the mineralization of wide range phenols. The results show that interstitial doping carbonates modification surface oxygen vacancy (OV) defects together contribute to formation VB tail states, substantially widen photoresponse range. Meanwhile, carboxylated carbon species induce substantial downward shift edge through coordination electron-withdrawing carboxyl groups, further enhances oxidation ability photogenerated holes. Accordingly, CC-OV-TiO2 exhibits superior stable performance.
