Topics in Current Chemistry, Journal Year: 2023, Volume and Issue: 381(6)

Published: Oct. 31, 2023

Abstract Human existence and societal growth are both dependent on the availability of clean fresh water. Photocatalysis is a type artificial photosynthesis that uses environmentally friendly, long-lasting materials to address energy environmental issues. There currently considerable demand for low-cost, high-performance wastewater treatment equipment. By changing structure, size, characteristics nanomaterials, use nanotechnology in field water filtration has evolved dramatically. Semiconductor-assisted photocatalysis recently advanced become among most promising techniques fields sustainable generation ecological cleanup. It beneficial, cost-effective, strictly linked zero waste discharge principle used industrial effluent treatment. Owing reduction or removal created unwanted byproducts, green synthesis photoactive nanomaterial more beneficial than chemical approaches. Furthermore, unlike methods, method does not require expensive, dangerous, poisonous ingredients, making it less costly, easy, photocatalyst synthesis. This work focuses distinct greener utilized production new photocatalysts, including metals, metal doped-metal oxides, plasmonic nanostructures, application intelligence machine learning design selection an innovative context challenges. A brief overview applications photocatalysts also presented. Finally, recommendations future research given create photocatalytic systems with greatly improved stability efficiency.

Published: July 14, 2023

Semiconductor-based photocatalytic reactions are a practical class of advanced oxidation processes (AOPs) to address energy scarcity and environmental pollution. By utilizing solar as clean, abundant, renewable source, this process offers numerous advantages, including high efficiency, eco-friendliness, low cost. In review, we present several methods construct various photocatalyst systems with excellent visible light absorption efficient charge carrier separation ability through the optimization materials design reaction conditions. Then it introduces fundamentals photocatalysis in both clean generation remediation. other parts, introduce approaches enhance activity by applying different strategies, semiconductor structure modification (e.g., morphology regulation, co-catalysts decoration, doping, defect engineering, surface sensitization, heterojunction construction) tuning optimizing conditions (such concentration, initial contaminant pH, temperature, intensity, charge-carrier scavengers). Then, comparative study on performance recently examined photocatalysts applied production remediation will be discussed. To realize these goals, H2 via water splitting, CO2 reduction value-added products, dye, drug photodegradation lessen toxic chemicals, presented. Subsequently, report dual-functional for simultaneous pollutant reactions. brief discussion about industrial economical applications is described. The follows introducing application artificial intelligence machine learning selection an innovative issues. Finally, summary future research directions toward developing significantly improved efficiency stability provided.

Nanomaterials for Photocatalytic Degradations of Analgesic, Mucolytic and Anti-Biotic/Viral/Inflammatory Drugs Widely Used in Controlling SARS-CoV-2

Catalysts, Journal Year: 2022, Volume and Issue: 12(6), P. 667 - 667

Published: June 18, 2022

The COVID-19 pandemic has been transformed into one of the main worldwide challenges, in recent years. For controlling symptoms that are caused by this disease (e.g., chills or fever, shortness breath and/or difficulty breathing, cough, sore throat, fatigue, headache, muscle aches, new loss tastes smells, congestion runny nose, nausea, vomiting diarrhea), lots medicines including analgesics, mucolytics, and anti-biotic/viral/inflammatory drugs have frequently prescribed. As these finally contaminate terrestrial aquatic habitats entering surface waterways through pharmaceutical production excreting trace amounts waste after human usage, they negative impacts on wildlife’s health ecosystem. Residual water potential to harm creatures disrupt their food chain as well breeding cycle. Therefore, proper degradation broadly used is highly crucial. In work, use nanomaterials applicable photocatalytic degradations analgesics acetaminophen, aspirin, ibuprofen, naproxen), mucolytics ambroxol), antibiotics azithromycin quinolones hydroxychloroquine chloroquine phosphate), anti-inflammatory glucocorticoids dexamethasone cortisone acetate), antihistamines diphenhydramine), H2 blockers famotidine), anthelmintics praziquantel), antivirals ivermectin, acyclovir, lopinavir/ritonavir, favipiravir, nitazoxanide, remdesivir) which widely controlling/treating coronavirus reviewed discussed.

A large number of pharmaceuticals and personal care products (PPCPs) persist in wastewater, the consumption PPCPs for COVID-19 control prevention has sharply increased during pandemic. This study investigated occurrence, removal efficiency, risk assessment six typical commonly used China two wastewater treatment plants (WWTPs). Ribavirin (RBV) is an effective pharmaceutical severely ill patients with COVID-19, possible biodegradation pathway RBV by activated sludge was discovered. The experimental results showed that were detected WWTPs a detection rate 100% concentrations ranging between 612 2323 ng L-1. frequency substantially higher, maximum concentration 314 Relatively high pollution loads found following from influent: ibuprofen > ranitidine hydrochloride ampicillin sodium clozapine sulfamethoxazole. efficiency closely related to adsorption sludge, moving bed biofilm reactor (MBBR) had higher capacity than anoxic-anaerobic-anoxic-oxic (AAAO) process. efficiencies sulfamethoxazole, sodium, ibuprofen, ranged 92.21% 97.86% MBBR process relatively low, 61.82% 97.62% AAAO process, lower 42.96% both processes. discrepancy caused temperature, hydrophilicity, hydrophobicity compound, acidity alkalinity. transformation identified, could be speculated as follows: first breaks into TCONH2 oxygen-containing five-membered heterocyclic ring under nucleosidase reaction, then finally formed TCOOH through amide hydrolysis. Aquatic ecological risks based on quotient (RQ) medium influent, RQ values all reduced after treatment. Ranitidine still effluent, respectively, thus presented potential aquatic ecosystem.
