The goal of this work is to determine the features of adsorption of N<sub>2</sub>O molecules followed by their interaction with a catalytic system based on metal nanoparticles at room temperature. Scanning tunneling microscopy and spectroscopy, as well as Auger spectroscopy, have been employed to identify the results and products of the adsorption of nitrous oxide on the surface of individual Pt nanoparticles synthesized on highly oriented pyrolytic graphite. It has been shown that, at short exposures, oxygen atoms resulting from dissociative adsorption oxidize the surface of nanoparticles only near the platinum–graphite interface. As the exposure increases, the entire surface of the nanoparticles is covered with oxide. Thus, it has been shown that the adsorption properties of the surface of the platinum nanoparticles on graphite are not the same, and this fact provides the possibility to carry out different chemical reactions on different surface regions, thereby increasing the efficiency of the catalytic system as a whole.</p><figure><div><div><div><picture><img></picture></div></div></div></figure></div></div>","PeriodicalId":521,"journal":{"name":"Colloid Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41086672","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}

An urgent task is to remove them in various ways, including the use of sorption technologies. Boron-selective sorbents with functional OH groups and granular anion exchangers with functional amino groups are capable of extracting boron compounds. This paper is devoted to studying boric acid sorption under static conditions on FIBAN A-5 fibrous sorbent, which shows a high affinity for boron and can be used as an alternative to anion-exchange resins produced in the form of granules. The features of the kinetics and equilibrium of the sorption by the studied fiber brought in contact with boric acid solutions have been studied. It has been found that the time required to reach the equilibrium state decreases with the intensification of stirring and an increase in the concentration gradient in a solution. Sorption isotherms are of a stepwise character due to the existence of boron in different forms at concentrations above 0.025 M. The influence of temperature, pH of a solution, and ionic form of the sorbent on the capacity of FIBAN A-5 fiber has been determined.</p><figure><div><div><div><picture><img></picture></div></div></div></figure></div></div>","PeriodicalId":521,"journal":{"name":"Colloid Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41086674","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}
