Present photocatalysts for the synchronous cleanup of pharmaceuticals and heavy metals have several drawbacks, including inadequate reactive sites, inefficient electron–hole disassociation, insufficient oxidation reduction power. In this research, we sought to address these issues by using a facile solvothermal-photoreduction route develop an innovative plasmonic S-scheme heterojunction, Au/MIL-101(Fe)/BiOBr. The screened-out Au/MIL-101(Fe)/BiOBr (AMB-2) works in durable high-performance manner both Cr(VI) norfloxacin (NOR) eradication under visible light, manifesting up 53.3 2 times greater NOR abatement rates, respectively, than BiOBr. Remarkably, AMB-2's ability remove Cr(VI)-NOR co-existence system is appreciably better sole-Cr(VI) environment; synergy among Cr(VI), NOR, AMB-2 results utilization photo-induced carriers, yielding desirable capacity decontaminating synchronously. integration MOF-based heterojunctions effect contributes markedly reinforced photocatalytic increasing number active augmenting visible-light absorbance, boosting efficient disassociation redistribution powerful photo-carriers, elevating generation substances. We provide details mechanism, decomposition process, bio-toxicity intermediates. This synergistic strategy modifying with noble metal opens new horizons devising excellent photosystems environment purification.

Increasing water pollution and decreasing energy reserves have emerged as growing concerns for the environment. These pollutions are due to dangerous effects of numerous pollutants on humans aquatic organisms, such hydrocarbons, biphenyls, pesticides, dyes, pharmaceuticals, metal ions. On other hand, need a clean environment, finding alternatives fossil renewable fuels is very important. Hydrogen (H2) regarded viable promising substitute fuels, range methodologies been devised generate this particular source energy. Metal-organic frameworks (MOFs) new generation nanoporous coordination polymers whose crystal structure composed juxtaposition organic inorganic constituent units. Due their flexible nature, regular structure, high surface area, these materials attracted much attention removing various from wastewater, splitting. MOFs Z-scheme heterojunctions identified an economical eco-friendly method eliminating wastewater systems, produce H2. Their low-cost synthesis unique properties increase application in environment fields. The possess diverse properties, exceptional making them ideal degradation separation. development formulation photocatalytic system using MOFs, which stable potent redox capability, has successful approach addressing environmental shortages recent times. Through utilization benefits offered by photocatalysts, efficient separation migration charge carriers, extensive spectrum light absorption, among advantages, notable enhancements can be attained. This review encompasses techniques, heterojunctions, use treating wastewaters, including heavy metals, Also, it provides overview mechanisms, pathways, theoretical practical aspects heterojunctions. Finally, thoroughly assesses existing challenges suggests further research applications industrial-scale treatment.

Nanomaterials for Environmental Applications

Published: Jan. 1, 2023

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.).

Microbial Biotechnology, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 1, 2025

ABSTRACT The inadequate removal of pharmaceuticals and personal care products (PPCPs) by traditional wastewater treatment plants (WWTPs) poses a significant environmental public health challenge. Residual PPCPs find their way into aquatic ecosystems, leading to bioaccumulation in biota, the dissemination antibiotic resistance genes (ARGs), contamination both water sources vegetables. These persistent pollutants can have negative effects on human health, ranging from development endocrine disruption. To mitigate these risks, there is growing interest exploiting microorganisms enzymes for bioremediation purposes. By harnessing metabolic capabilities microbial communities, be efficiently degraded, transformed, or sequestered systems. Additionally, communities exhibit remarkable adaptability resilience diverse PPCP contaminants, further underscoring potential as sustainable cost‐effective solutions treatment. This review explores promise an approach addressing complex challenges posed contamination, emphasising its safeguard integrity well‐being.
