Abstract
The catalytic properties of silver-ceramic catalysts (6 wt % Ag) in me thanol oxidation to formaldehyde are found to depend substantially on the calcination temperature in air (900 - 1350 degrees C) and silicate modulus of a support. The results of thermal-gravimetric, X-ray diffr action, and electron-microscopic investigations allow one to conclude that the observed character of these dependences is due to the differe nces in the phase composition of the support, which affects the disper sion of silver species.
