摘要
The interaction of metal components with silica support in Na-W-Mn/SiO2 was studied. The inducing effect of sodium makes amorphous silica transferred to α-cristobalite during calcination, and the specific surface area decreases enormously as a consequence. When sodium alone is loaded, the silica has almost no micropores retained after calcination. When tungsten is loaded together with sodium, quite regular pores at the size of micron can be formed in silica during the phase transition.
