The physicochemical properties of the samples were determined by using XRD, TEM, N2 adsorption (BET method), H2-TPR, and NH3-TPD. The Ce–Mn/TiO2 exhibited a higher NO conversion than Ce–Mn/ZSM-5 in the 100-200°C temperature range, but the NO conversion of Ce–Mn/ZSM-5 increases with reaction temperature (being the N2 selectivity close to 100%) whereas, for Ce–Mn/TiO2, the N2 selectivity extremely decreases. The reducibility and surface acidity of samples seems to explain the catalytic performance. Thus, although the reducibility of Ce–Mn/ZSM-5 and Ce–Mn/TiO2 was similar, the large number of surface acid sites of Ce–Mn/ZSM-5 could be a plausible reason for its excellent SCR activity. In fact, the superior SCR activity of Ce–Mn/ZSM-5 (94% NO conversion and 95% N2 selectivity at 300°C) is related to the presence of well-dispersed Ce–Mn mixed oxide nanoparticles, high reducibility, and a large number of surface acid sites.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141519680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This class of surfactants was synthesized from fatty acids by a photochemical process and present good physico-chemical properties and good biodegradability. The inhibition performance was evaluated by weight loss and electrochemical techniques: linear polarization resistance and electrochemical impedance spectroscopy. The results showed that these surfactants are good inhibitors; the inhibition efficiency increases with increasing concentration surfactants. In addition, the increase of chain length surfactants leads to the best inhibition efficiency for sodium sulfo palmityl methyl ester surfactant with 95.27, 98.20, and 95% via weight loss, linear polarization resistance and electrochemical impedance spectroscopy, respectively. Scanning electron microscopy–Energy dispersive X-ray allowed the visualization of a good adhesion of the protective deposit formed by the surfactants on the carbon steel surface including the elements presents on this surface as sodium and sulfur.

One viable approach to address this issue involves the implementation of nano-additives into the membrane matrix. In this research, the potential of chamomile leaf nanoparticles (Chm NPs) as an eco-friendly material for use in UF membrane synthesis was explored. To better understand the impact of Chm on the production of PES UF membranes, a range of membranes were created by introducing varying amounts of Chm into the casting solution. The produced membranes were thoroughly evaluated, focusing on aspects such as porosity, pore size, hydrophilicity, membrane morphology, and UF performance. Manufactured PES/Chm membranes demonstrated significantly increased permeate water flux (PWF) (up to 367 L/m2 h), which was three times that of the pristine PES membrane (126 L/m2 h). Beside Methylene Blue dye (MB) rejection, it was obtained a high removal percent of about 94 %. Additionally, decreased contact angle (C.A.) for modified membranes (47%), compared with pristine PES membranes, all these results led to enhance the membrane permeate flux and rejection. The utilization of chamomile as a novel environmentally friendly addition holds significant potential in the production of UF membranes for wastewater treatment.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141504680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
