Sorption analysis of composites based on zinc oxide for catalysis and medical materials science

Received: 19.10.22. Revised: 10.11.22. Accepted: 12.11.22. Available online: 22.11.22.Silver-modified zinc oxide nanostructures and nanocomposites based on zinc oxide and hydroxyapatite were obtained via chemical deposition method.The specific surface area was 5–20 m2/g, the nanoparticle sizes were 60–260 nm, depending on the synthesis features.The use of silver nanoparticles leads to a decrease in the specific surface area of zinc oxide modified with silver and increases the rate of photocatalytic decomposition.The authors are grateful to Khalugarova Kamilya for assistance in obtaining composites based on hydroxyapatite and zinc oxide by pressing and to Arina Zaikina (TESCAN) for SEM data.Modified structures based on zinc oxide are of special interest in catalysis and medicine. The work discusses the composite structures based on zinc oxide and hydroxyapatite, as well as silver-modified zinc oxide nanostructures obtained by chemical deposition. The obtained materials were studied using a Rigaku SmartLab diffractometric complex and a Sorbi MS sorption analyzer. The specific surface area was studied and the average size of nanoparticles in the samples is determined. The application scope of the considered materials was catalysis and medicine, including the use in bone engineering as bioactive coatings deposited on the surface of a metal bioimplant.This work was supported by the Russian Science Foundation (grant no. 22-29-20162), https://rscf.ru/project/22-29-20162/ with the St. Petersburg Science Foundation (agreement No. 19/2022 dated April 14 2022)
