Abstract
The modified sol-gel technique for the preparation of Со, Ni, Mo and W oxides nanoand submicron powders as well as binary composites based on them was developed. The optimal parameters of synthesis of metal oxide nanopowders with a particle size less than 100 nm were determined. The developed approach allows to obtain the nanoscale metal oxide particles with the given sizes, varying their within range 10-1000 nm. Mesoporous composites containing Mo-, Co-, Ni-oxides, Al2O3 and Ti-silicate were synthesized, characterized and tested in the catalytic alcohol synthesis from CO and H2. It was found that selectivity to C1-C4-alcohols formed over model catalytic systems reaches 50-85% in temperature range 280-360°С.
