Engineering of self-disinfecting surfaces to constrain the spread SARS-CoV-2 is a challenging task for scientific community because human coronavirus spreads through respiratory droplets. Titania (TiO2) nanocomposite antimicrobial coatings one ideal remedies disinfect pathogens (virus, bacteria, fungi) from common under light illumination. The photocatalytic disinfection efficiency recent TiO2 surfaces, dental and orthopaedic implants are emphasized in this review. Mostly, inorganic metals (e.g. copper (Cu), silver (Ag), manganese (Mn), etc), non-metals fluorine (F), calcium (Ca), phosphorus (P)) two-dimensional materials MXenes, MOF, graphdiyne) were incorporated with regulate charge transfer mechanism, surface porosity, crystallinity, microbial efficiency. activity was evaluated against most crucial pathogenic microbes such as Escherichia coli, methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Legionella pneumophila, Streptococcus mutans, T2 bacteriophage, H1N1, HCoV-NL63, vesicular stomatitis virus, bovine coronavirus. Silane functionalizing agents polymers used coat titanium (Ti) metal introduce superhydrophobic features avoid adhesion. disclosed exceptional bio-corrosion resistance, durability, biocompatibility, bone-formation capability, long-term Moreover, commercial trend, techno-economics, challenges, prospects also discussed briefly.

It is well-documented that large-scale pollution generated by human activity has a dramatic impact on ecosystems. In this context, removing harmful chemicals via photocatalysis tremendous potential as depollution method, utilizing freely available solar light and catalytic materials with low or negligible ecotoxicity. The main drawbacks, which aren’t often addressed in the literature, are formation of intermediate products, reaction rates, limited catalyst stability, difficult recovery. most cases, published works assess efficiency tested photocatalysts from pollutant degradation studies, whereas identifying quantifying by-products not conducted. This review summarizes recent advances reported for photocatalytic removal some organic (e.g., alcohols, carboxylic acids, volatile compounds, phenol) inorganic NO3−) contaminants. various UV- visible-light active pathways were explained, emphasizing factors contributing to their mineralization. mechanisms, identification quantification intermediates, implication reactive species (ROS) discussed analyzed each category model target pollutant. Additionally, actual challenges future approaches improve environmental remediation presented.

Airborne contaminants pose significant environmental and health challenges. Titanium dioxide (TiO2) has emerged as a leading photocatalyst in the degradation of air compared to other photocatalysts due its inherent inertness, cost-effectiveness, photostability. To assess effectiveness, laboratory examinations are frequently employed measure photocatalytic rate TiO2. However, this approach involves time-consuming requirements, labor-intensive tasks, high costs. In literature, ensemble or standalone models commonly used for assessing performance TiO2 water contaminants. Nonetheless, application metaheuristic hybrid potential be more effective predictive accuracy efficiency. Accordingly, research utilized machine learning (ML) algorithms estimate photo-degradation constants organic pollutants using nanoparticles exposure ultraviolet light. Six metaheuristics optimization algorithms, namely, nuclear reaction (NRO), differential evolution algorithm (DEA), human felicity (HFA), lightning search (LSA), Harris hawks (HHA), tunicate swarm (TSA) were combined with random forest (RF) technique establish models. A database 200 data points was acquired from experimental studies model training testing. Furthermore, multiple statistical indicators 10-fold cross-validation examine established model's robustness. The TSA-RF demonstrated superior prediction among six suggested models, achieving an impressive correlation (R) 0.90 lower root mean square error (RMSE) 0.25. contrast, HFA-RF, HHA-RF, NRO-RF exhibited slightly R-value 0.88, RMSE scores 0.32. DEA-RF LSA-RF while effective, showed marginally 0.85, values 0.45 0.44, respectively. Moreover, SHapley Additive exPlanation (SHAP) results indicated that rates through photocatalysis most notably influenced by factors such reactor sizes, dosage, humidity, intensity.
