Effective synthesis of zeolite-encapsulated Ni nanoparticles with excellent catalytic performance for hydrogenation of CO2 to CH4

Abstract

A simple and effective “synchronous exchange deposition” method was developed, for the first time, for the synthesis of an encapsulation of Ni nanoparticles uniformly distributed in X-zeolite (Ni@NaX). The short-range joint effects of the Ni nanoparticles and the 3D negatively charged grid of the X-zeolite endowed Ni@NaX with an excellent catalytic performance for the hydrogenation of CO₂ to CH₄.
