关键词: RE-Al/SBA-15;稀土改性;酯化;烷基化 Abstract The mesoporous molecular sieve SBA-15 has attracted considerable attention in the fields of catalytic chemistry and adsorption-separation, due to high surface area, uniform pore size and tunable pore structure, high thermal and hydrothermal stabilit...
while the meso -structure could be collapsed when these ratios are more than 0.20because of the adverse effect of amino groups on the formation of SBA -15.However,with the aid of fluoride ions,even at a molar ratio of APTES to (APTES+TEOS)of 0.25,the amino -functionalized SBA -15...
