The ability to adroitly tailor acid-strength using specifically-engineered bimetallic nanoporous materials has been investigated with a view to exploiting their potential in solid-acid catalysed transformations. Further, it has been demonstrated that through site-specific interactions, extra-framework zinc ions can suitably modify the acidity of Brønsted acid sites, to stimulate diverse catalytic responses, when combined with isomorphously-substituted framework metal cations within porous architectures, for the Beckmann rearrangement of cyclohexanone oxime and in the isopropylation of benzene.
人们研究了使用专门设计的双金属纳米多孔材料巧妙地调整酸强度的能力，以期利用它们在固体酸催化转化中的潜力。此外，已经证明，通过特定位置的相互作用，额外的骨架锌离子可以适当改变 Brønsted 酸位的酸度，从而在与多孔结构中的同晶取代骨架金属阳离子结合时，刺激各种催化反应，用于环己酮肟的贝克曼重排和苯的异丙基化。
