Synthesis and Properties of Ceramic Photocatalytic Materials
Strejček, Josef ; Maca, Karel (referee) ; Cihlář, Jaroslav (advisor)
Two methods of synthesis of ceramic catalytic perovskite materials for fotochemical decomposition of water and partial oxidation of methane were studied. The method based on mechanochemical activation of oxide reactants followed high temperature solid state reaction made possible preparation of almost one phase perovskites of InVO4, InNbO4, InTaO4, EuVO4, EuNbO4 a EuTaO4. Pseudo sol-gel synthesis combined with high temperature solid state reaction lead to one phase perovskites or products with more than 90% of perovskites phase of the Sm-Ca-Co-Al-O type.

Study of the synthesis and structure of ceramic perovskite materials for energy applications
Strejček, Josef ; Bartoníčková, Eva (referee) ; Cihlář, Jaroslav (advisor)
Method, so called “glycin- nitrate process”, combined with high temperature solid state reaction, of preparation multi- component ceramic perovskite materials was studied. Two types of perovskite systems were prepared by this method. Firs one, based on LaNiO3 doped by calcium and aluminium and second one, based on SmFeO3 doped by calcium and nickel or cobalt. This method made possible preparation of one phase perovskite or perovskites with few percent of nickel in form of oxide. In systems containing both nickel and calcium another phases rich in calcium and nickel appeared.
