Fabrication of hybrids of zeolitic imidazolate frameworks supported zero-valent copper nanoparticles as a non-noble catalyst with high efficiency

This work integrated zero-valent copper (ZVC) onto the surface of zeolitic imidazolate framework (ZIF) to form hybrids of ZVC/ZIF-8 as a non-noble catalyst for catalytic reduction of PNP as a reliable model reaction. The ZVC/ZIF-8 exhibited superior catalytic properties and good recyclability after the fabrication. 6%ZVC/ZIF-8 hybrids complete the reduction process in 2 min with a rate constant estimated to be 2.39 min −1 . The study’s findings explored a simple and powerful way to incorporate metal ions into the backbones of open framework materials without losing their properties.
