Preservation of life and health of the military personnel of the Armed Forces of Ukraine, employees of the State Emergency Service of Ukraine, civilian population in military and post-war conditions, when the composition of emergency chemically hazardous substances (ECHS) in the air is unknown, and their concentration significantly exceeds the maximum allowable concentration. The goal can be achieved by creating a scientific basis for the development of highly effective catalyst for low-temperature oxidation of carbon monoxide (CLTO-CO), as well as single-layer biocidal chemisorption-filtering materials (BCSFM) with active "response" indication (BCSFM-AI) for equipping gas mask boxes of personal respiratory protective equipment (RPE). This will be achieved by establishing the structural, morphological, physicochemical and catalytic characteristics of CLTO-CO; the creation and study of the protective properties of single-layer BCSFM-AI for use in conditions of containing various types of ECHS in the air; development of an active indication unit. This will allow optimizing the location of the indicator unit, as well as developing gas mask filters that effectively clean the air from bio-arosales (bacteria, fungi), gases (CO, SO2, NH3) and vapors of various nature, and on this basis, develop designs for gas mask filters for RPE.

The project is aimed at creation of scientific foundations of development of highly efficient catalysts of low-temperature carbon monoxide oxidation (CLO-CO) as well as biocidal filtering chemisorption materials (BFCSM) with active indication for equipping gas-proof boxes for personal respiratory protective equipment.
The influence of structural and physicochemical properties of SiO₂, Al₂O₃, and zeolites NaA, KA, NaX on low-temperature CO oxidation catalyst activity was studied. It was demonstrated that catalyst activity depends on porosity, specific surface area, hydration level, and acid-base properties of the support. Zeolites show high water affinity and Lewis basic centers, while oxide supports exhibit different acidic properties. On zeolite supports, Pd(II) and Cu(II) localization limits synergistic effects, whereas SiO₂ and Al₂O₃ provide higher activity.
Regularities of the influence of support type, humidity, and temperature on CO oxidation kinetics were established. Recommendations were developed for support selection and operational conditions to enhance efficiency and reduce precious metal consumption.
Based on the results of generalizing of literature data on the chemical and toxicological properties of alkylamines and their reactivity towards acid gases (SO2), justification of the choice of ethanolamines and their citrates as precursors for the production of chemisorbents was carried out.
The use of aqueous monoethanolammonium citrates in the impregnation of fibrous carbon nonwoven material made it possible to obtain chemisorption-filtering materials (CSFM) capable of absorbing both acidic (SO2) and basic (NH3) gases, as well as vapors of organic compounds (C6H6 and CH3OH). To register the change in the color of the surface of the indication FCSM, it is proposed to equip gas-dust respirators with a developed active indication unit. A model of a gas-dust respirator has been developed.
