The key research activities of the laboratory are driven by scientific questions that are closely related to energy management based on renewable energy sources, energy efficiency, creating conditions for environmental safety, and reducing environmental impact. The experimental work is being carried out using modern methods in topics such as the chemical storage of renewable energy, the catalytic implementation of selective and energy-efficient chemical transformations, or the application of solutions aiming at the reduction of fossil-based raw material usage.

The laboratory has a long history and its activities have developed from the application of radioactive isotope labeling to address catalysis-related questions. The main field of research for decades was the study of the catalytic transformation of hydrocarbons by using various catalysts, first unsupported metals, later systems involving supported mono- and bimetallic catalysts and transition metal clusters. Environmental catalysis research began in the 1990s with the study of nitric oxide conversion processes and the complete combustion of volatile organic compounds. Later, in collaboration with the Radiation Chemistry Department, they achieved success in the treatment of industrial wastewater by combining catalytic transformations and those initiated by high-energy radiation. Catalytic processes related to alternative energy production, such as CO removal from hydrogen by the PROX reaction and dry reforming of methane, emerged as a defining direction in the 2000s, and the catalytic conversion of greenhouse gasses (CO2 and CH4) is still being intensively explored. It is important to mention the experience gained with catalysts for selective oxidation transformations (glucose, alcohols), enantioselective hydrogenation, diesel desulfurization and the catalytic oxidation of carbon monoxide, moreover, the oxidation or reduction of nitrogen oxides on model catalysts and large surface area oxide supported ones, with green chemical principles in mind. Recently, the study of electrode catalysts for electrolytic water splitting has become a defining field, which is related to the chemical storage of renewable electricity.
