The results confirm the effect of the gas phase consisting of the starting components of the catalyzed reaction on improvement of the performance of the catalyst obtained upon thermal decomposition of its initial metastable state: in situ catalyst “self-adjustment” effect. The best catalytic properties for ODM reaction are offered by bismuth silicate (Bi
