Quasi-two-dimensional (QTD) structural heterogeneous catalysts have attracted a broad interest in multidisciplinary research due to their unique structure, preeminent surface properties and outstanding catalytic performance. Herein, a HZIF@TCPP-Fe/Fe heterogeneous catalyst based on cross-linked surface engineering is constructed by supporting QTD TCPP-Fe/Fe ultra-thin metallized film (approximate to 2 nm) on hollow skeleton of zeolite imidazolate frameworks. The designed QTD structure exhibits high efficiency for the catalytic oxidative dehydrogenation of aromatic hydrazides reactions which is the key technology in various industrial processes. Taking advantage of QTD structure with excellent accessibility, the metallized film with irregular defects not only enhances electron transfer during the reaction but also exposes more surface-active sites. Furthermore, the prepared HZIF@TCPP-Fe/Fe heterogeneous catalyst can be recycled and reused, which is of great significance in the field of green chemistry.
