Materials and Processes in Environmental Protection

Field of scientific interest

The efforts of the researchers at Laboratory for Materials and Processes in Environmental Protection are focused on the development of new types of catalysts for application in catalytic reactions for environmental protection as complete oxidation of volatile organic compounds (VOCs, including methane), NOx reduction and CO oxidation.

The systematic investigations are directed to experimental evaluation and mathematical modeling of reaction kinetics for further implementation of the experimental techniques in development of structured catalysts, based on different substrates as Al-containing stainless steel, anodized aluminum, ceramics etc.

The scientific background at the laboratory includes synthesis of nanosized and nanostructured materials, based on supported metal or metal oxides with an optimal effectiveness in abatement of VOCs and nitrogen oxides in waste gases, preparation of mineral and carbon sorbents for elimination of green house gases, investigation of textural and surface characteristics of different materials.

The studies are also directed to the utilization of waste materials from food and perfumery industries, heat generating plants and others as a renewable resource by processing it into valuable products used for environmental protection. More specifically, the subjects are concentrated in three main areas: screening of efficient sorbents for removal of metal ions, dyes and pigments from wastewaters, optimization of process parameters and clarification of the mechanism of sorption.
