| Abstract: | The scientific principles were formulated that underlie an integrated approach to development and synthesis of bulk and membrane
catalysts for methanol transformation to dimethyl ether and hydrogen which are environmentally friendly fuels. The results
were summarized for studies into relationships in formation of phosphates MZr2(PO4)3 (M = Na, K, Rb, Cs, Mg0.5, Ca0.5, Sr0.5, Ba0.5, Zr0.25), Cu0.5(1+y)Fe

, and molybdate Ni0.3Cr0.4Fe1.4(Moo4)3 with the desired structure and properties controllable by variation of their chemical composition and synthesis parameters.
The surface characteristics and catalytic properties of the resulting systems and the yields of the target product formed
from methanol transformations in inert and oxidizing atmospheres were analyzed in relation to the catalyst synthesis condition. |
