Ionic liquid and lysine co-assisted synthesis of the highly dispersed Ni/SAPO-11 catalyst

Abstract

The synthesis of highly-dispersed non-noble based catalysts and its application on hydrogenation /dehydrogenation still remains challenging. Therefore, it is of great importance to protect metal from aggregation in both calcination...

Synthesis of bimetallic Ni-Pt/SAPO-11 composite and the catalytic application in n-heptane hydroisomerization

“…In hydroisomerization area, catalysts containing single metal Ni often exhibit relatively poor catalytic activity and severe cracking reactions [8]. The catalysts loading Ni tend to migrate and aggregate into large nanoparticles as Ni has low polarizability and weak interaction with the molecular sieve carrier, leading to poor metal function [9]. In addition, due to electronic structure characteristics, metal Ni exhibits relatively strong Ni-H interaction, which is not conducive to the desorption of H species at the Ni site [10].…”
