A facile hydrothermal etching-healing strategy is proposed to fabricate Sn-MWW zeolite without using any supporting agents and additives. This approach has the advantages of low organic structure-directing agent consumption and rapid growth, resulting in successful Sn introduction and excellent catalytic performance.
A facile hydrothermal etching-healing strategy is proposed to fabricate a Sn-MWW zeolite based on a pure silica ITQ-1 precursor, which avoids using any supporting agents and additives, such as B3+ and Na+. Thus, post-synthetic acid treatments for the removal of such additives to ensure catalytic performance are not required, which is a great improvement to the conventional Sn-MWW synthetic route. Moreover, low organic structure-directing agent (SDA) consumption and rapid growth make this approach practically attractive. The growth mechanism study reveals the crucial etching and healing dual functional role of the SDA, which leads to successful Sn introduction. The obtained Sn-MWW exhibits excellent glucose isomerization catalytic performance owing to the clean (without the side effect of additives) and well-defined Sn sites.
