Abstract

The invention mainly relates to a preparation method for a carbon nitride supported monodisperse oxidation state metal atom catalytic material, in particular to a preparation method of a layered graphite-phase carbon nitride supported monodisperse oxidation state metal M atom composite (M is one or two or more of Zn, V, Fe, Co, Ni, Sn, Pb, Cu, In and Mn), and belongs to the field of catalytic materials. The method adopts a way of complexation of a metal precursor and a carbon nitrogen precursor to inhibit agglomeration of metal atoms, and employs one-step pyrolysis of a metal carbon nitrogen adduct to prepare the carbon nitride supported monodisperse oxidation state metal atom catalytic material, wherein the metal M exists in the form of partial or complete oxidation state single atoms, and the varieties and composition of the supported metal atoms can be regulated as needed. The method of the invention has the characteristics of simplicity and easy control, and can be used for mass preparation of the carbon nitride supported monodisperse oxidation state metal atom catalytic material.

Description

technical field

[0001] The present invention mainly relates to a preparation method of a carbon nitride-supported monodisperse oxidation state metal atom catalytic material, specifically a layered graphite phase carbon nitride supported monodisperse oxidation state metal M atom composite material (M is Zn, V, The preparation method of one or more of Fe, Co, Ni, Sn, Pb, Cu, In, Mn) belongs to the field of catalytic materials.

[0002] Background technique:

[0003] Single-atom catalysis is of great significance for the practical application of catalysts (X. Yang, A. Wang, B. Qiao, J. Li, J. Liu, T. Zhang. Accounts of Chemical Research, 2013, 46, 1740-1748.) . For high-loaded metal catalysts, only a small number of metal active components play a catalytic role in the catalytic reaction process. In comparison, single-atom catalysis where each metal atom acts as an active site is much more efficient than traditional supported metals. The metal utilization efficiency of the cata...
