The catalytic oxidation of CO is probably the most investigated reaction in the literature, for decades, because of its extended environmental and fundamental importance. In this paper, the oxidation of CO on La1−xSrxMnO3 perovskites (LSMx), either unloaded or loaded with dispersed Ir nanoparticles (Ir/LSMx), was studied in the temperature range 10...

Antidepressants are released into the aquatic environment because of their incomplete removal from wastewater treatment plants. In the present work, we investigated the photochemical degradation of a commonly prescribed antidepressant, namely sertraline, in aqueous matrices. The molar absorption coefficient of sertraline at 254 nm and at various pH...

Selective catalytic reduction (SCR) is probably the most widespread process for limiting NOx emissions under lean conditions (O2 excess) and, in addition to the currently used NH3 or urea as a reducing agent, many other alternative reductants could be more promising, such as CxHy/CxHyOz, H2 and CO. Different catalysts have been used thus far for NO...

The increasing presence of contaminants of anthropogenic origin in the aquatic environment raises the concern of the scientific community (Patel et al., 2019). Antiviral drugs play an important role, as their presence in aquatic bodies is associated with antiviral resistance and chronic toxicity to aquatic organisms (Nannou et al., 2020). Acyclovir...

Several categories of PhACs (Picture 1) have been detected in surface water, groundwater, effluents of WWTPs, drinking water (from a few ng/L to μg/L). • Sertraline (SER) belongs to SSRIs, prevalent class of antidepressants, and is administered for the treatment of major depression and others symptoms such as panic and anxiety. • SER has been deter...

The aim of present work was the study of the degradation of cephalosporins under UV-C irradiation in aqueous matrices

In recent years, scientists show great concern about the presence of endocrine disrupting compounds (EDCs) in the aquatic environment. EDCs include a family of emerging microcontaminants that have the ability to interact with the endocrine system of the organisms, causing various developmental and reproductive disorders. The occurrence of these sub...

The efficiency of TiO2 photocatalysis to degrade three estrogen hormones, i.e. 17α-ethynylestradiol (EE2), estrone (E1) and 17β-estradiol (E2), in environmentally relevant samples was investigated. Radiation at a photon flux of 1.7×10-7 einstein/s was provided by a solar simulator and experiments were conducted at various TiO2 loadings (25-1500 mg/...

The N 2 O decomposition and reduction by CO or C 3 H 6 over rare earth oxides (REOs)-modified Pt/Al 2 O 3 structured catalysts, i.e., coated on ceramic honeycomb monoliths, were comparatively investigated in a wide temperature interval of 100–600 • C, either in the presence or in the absence of excess O 2 and H 2 O. It was shown that the de-N 2 O e...

a b s t r a c t The efficiency of heterogeneous photocatalysis to degrade 17-ethynylestradiol (EE2), a synthetic estro-gen hormone, in environmentally relevant samples was investigated. In most cases, UV-A radiation at a photon flux of 2.81 × 10 −4 einstein/min was provided by a 9 W lamp and experiments were conducted at various concentrations of A...

The photocatalytic degradation and mineralization of the antibiotic sulfamethoxazole (SMX) in aqueous TiO2 suspensions was investigated. UV-A irradiation was provided by a 9W lamp at a photon flux of 2.81×10−4Einstein/min and runs were performed at SMX initial concentrations between 2.5 and 30mg/L, six commercially available TiO2 catalysts at loadi...

BACKGROUND: Although chlorination is an effective and widely employed method of water disinfection, it suffers serious drawbacks such as the formation of toxic chlorinated by-products. Therefore, other disinfection technologies have been researched and developed, including advanced oxidation. RESULTS: The efficacy of heterogeneous photocatalysis an...
