Research and development activity in the field of catalytic membrane reactor is based on application of advanced nanomaterials and technologies of their manufg. Despite tremendous efforts worldwide in this area, a lot of crit. scientific and technol. problems remain unsolved. This includes design of nanostructured perovskites with a high oxygen mobility at intermediate temps., selection of materials for effective incorporation of oxygen into the lattice, co-sintering of thin green ceramic films deposited on porous substrates (including those based on a glass matrix), and development of selective catalyst for the partial oxidn. of methane by the lattice oxygen transferred through membrane. The importance of purity of reagents is discussed for design of microporous mixed ionic-electron conducting ceramic membranes. However, all specified problems are conjugated, so they are to be solved simultaneously. This makes the soln. of this problem, the design of advanced nanostructured materials and devices, a demanding task due to its interdisciplinary character.
