“…From the transmittance spectra, it can be observed that prepared films are highly transparent in the visible region with a red shift of (Ti-Ce), (Ti-Ce-Sn) compared with (Ti) and (Ti-Sn) and this is an indication that these films have a narrow bandwidth [65]. Increased transmission is also linked with film crystallinity [68] and consequently, to photocatalytic activity.…”

Analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) such as paracetamol, diclofenac, and ibuprofen are frequently encountered in surface and ground water, thereby posing a significant risk to aquatic ecosystems. Our study reports the catalytic performances of nanosystems TiO2 -MexOy (Me = Ce, Sn) prepared by the sol-gel method and deposited onto glass slides by a dip-coating approach in the removal of paracetamol from aqueous solutions by catalytic ozonation. The effect of catalyst type and operation parameters on oxidation efficiency was assessed. In addition to improving this process, the present work simplifies it by avoiding the difficult step of catalyst separation. It was found that the thin films were capable of removing all pollutants from target com-pounds to the oxidation products.

“…As can be seen, changes in the pH and process temperature do not have a significant effect on RB5 decolorization (Figure 8b,c). In the whole analyzed range of pH (2)(3)(4)(5)(6)(7)(8)(9) and temperature (20-70 °C), the decolorization efficiency is about 99%. Poorer results are obtained for the removal of AG25 dye.…”

“…Catalytic materials have been intensively researched in recent years with regard to their high activity in hydrogen evolution, pollution degradation, CO 2 remediation and environmental purification [1,2]. TiO 2 and ZnO are well-known semiconductor catalysts offering stability and economic advantages [3,4]. TiO 2 is an interesting candidate for environmental protection applications due to its non-toxicity, biological and chemical stability, strong oxidizing properties, low price and resistance to corrosion [5,6].…”

A TiO2/ZnO oxide system was proposed as a support for the immobilization of laccase from Trametes versicolor (LTV). The obtained TiO2/ZnO/LTV biocatalytic system was then applied in the decolorization/degradation of C.I. Reactive Black 5 and C.I. Acid Green 25 dyes. The efficiency of immobilization was evaluated based on catalytic properties (Bradford method, oxidation reaction of 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) and physicochemical (spectroscopic, porous, electrokinetic) analysis. The immobilization process was carried out with high performance (99.4%). Immobilized laccase retained about 40% of its activity in the whole analyzed temperature range and after 10 reaction cycles. Immobilization efficiency was also indirectly confirmed by the presence of characteristic functional groups (–C–H and –C–O), nitrogen and carbon on the TiO2/ZnO/LTV biocatalytic surface, identified by spectroscopic analyses. The increase in the surface area to 126 m2/g, change of isoelectric point (2.0) and zeta potential ranges (from +12.0 to −20.0 mV) after the immobilization process were also observed. The results show that the designed biocatalytic system enables the removal of acid dyes (C.I. Reactive Black 5 and C.I. Acid Green 25) with high efficiency (99% and 70%, respectively). Mass spectroscopy analysis indicated possible degradation products formed by the cleavage of N=N and C–N bonds.
