Creating a virtual device for processing the results of sorption measurements in the study of zinc oxide nanorods

Abstract

The work is devoted to the creation of a virtual device (computer program) for processing the results of sorption analysis of nanomaterials, including for estimating the size of nanoparticles based on the specific surface area. The obtained evaluation results were compared with the scanning electron microscopy data. Photocatalytically active zinc oxide samples were chosen as the object of the study.

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

“…As part of the work, a series of adsorption isotherms was studied in the range of relative partial pressures of adsorbate gas (nitrogen) P/Po 0-20%, the specific surface area of each composite was determined by the standard Brunauer-Emmett-Teller (BET) method, and the average particle size in the sample was estimated. The average particle size was estimated using the data on the specific surface area and density according to the method described in [26].…”

“…At present, sorption methods of analysis, including the method of thermal nitrogen desorption (NTD), are widely used to characterize the porous structure parameters of nanomaterials for a wide range of functional purposes. NTD belongs to the group of non-destructive techniques that provide express analysis of such parameters of nanomaterials as specific surface area, average particle size, mesopore size distribution, and presence or absence of micropores in the system [26].…”

Morphology Effects on Electro- and Photo-Catalytic Properties of Zinc Oxide Nanostructures

“…ZnO rods were prepared using the direct thermal decomposition method [ 37 , 38 ]. Cheap zinc acetate dihydrate was directly calcinated in a muffle furnace in the air at high temperatures for different durations.…”

Overview of sorption analysis capabilities for meso- and microporous zeolites nanomaterials

“…The features of the thermal desorption method realized in Sorbi MS are discussed in [9,10]. When studying compositions by the thermal desorption method of nitrogen, the choice of the analysed material mass is determined by two factors: the possibility of obtaining a stable desorption signal, which is used to calculate the volume of desorbed gas, and the range of the total measured surface S = S sp •m.…”
