New multi-component aerogels for environmental catalysis
Annotation in Czech
The aim of the project is to study the synthesis and properties of multi-component aerogels and their modification and transformation into environmental catalysts. In terms of the project target, multi-component perovskite precursors of the type of La (Sm, Gd, ..) - Co (Ni, Fe, ..) - Ca (Sr, ..) - Al (Y, Sc, ..), composite aerogels on Ti, Zr, Al, Ce, Sc, Y, Ln and AE oxides modified with the transition elements Co, Ni and Fe, and metal-doped anatase-brookite photocatalysts (Pt, Ni, Co, Cu, Ag) will be studied. In sol-gel syntheses, complex (chelate) methods will be used to allow homogeneous distribution of cations in aerogels such as the synthesis of metal ion-chelate polymer gels method, the epoxide-assisted sol-gel methods, and the metal-oxane polymer sol-gel method. The structure and properties of the aerogels resulting from the hydrolysis and condensation of these complexes make it possible to prepare catalysts with high efficiency and selectivity due to the even distribution of the active centres on the surface of the aerogel catalysts. Research will focus on environmental catalytic aerogels for the production of hydrogen gas by reforming greenhouse gases (methane, carbon dioxide) and photocatalytic decomposition of water and alcohols. The project should bring new knowledge about the preparation and properties of multi component aerogels suitable for the preparation of stable and robust reforming catalysts with high activity, selectivity and stability, and photocatalysts for the decomposition of water and organic matter. International cooperation within the COST Action CA18125 is in this project important for solving the problem of supercritical aerogel drying, in which the Hungarian partner plays an important role. The international consortium of partners in the COST Action allows an intensive and very broad exchange of theoretical and practical experience obtained in Aerogel research that is not easy to gain in any other way.

Project results evaluation
New methods for the synthesis of TiO2 aerogels and multicomponent aerogels containing Sm, Al, Co, Ni, Fe and Cu were developed and their catalytic action in the production of hydrogen by photolysis of water and the reformation of methane with carbon dioxide was studied. Biphasic anatase-brookite nanoparticles prepared by an original "bridge" sol-gel synthesis had a high photocatalytic activity during the photolysis of water. Sm-Co-O and Al-Co-Ni-O aerogels showed CH4 and CO2 conversion of 99% to H2 and CO and negligible C-deposition during methane reforming. The mentioned catalysts are potentially usable in environmental catalysis.
