▎ 摘　　要

NOVELTY - Preparing functionalized magnetic oxide graphene oxide catalyst material containing hydroxylamine compound comprises dispersing graphene oxide, trivalent iron salts and hydroxylamine-containing compounds at 100-300 degrees C, and performing hydrothermal reaction, where mass ratio between graphene oxide, trivalent iron salt and hydroxylamine-containing compound is 1:0.5-6:50-200. USE - The catalyst material is useful as Fenton catalyst for Fenton oxidative degradation of water in organic system (claimed). ADVANTAGE - The catalyst material has simple process and mild condition; and is safe, environmentally friendly and suitable for large-scale industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) functionalized magnetic oxide graphene oxide catalyst material containing hydroxylamine compound obtained by above method; and (2) use of functionalized magnetic oxide graphene oxide catalyst material containing hydroxylamine compound as Fenton catalyst for Fenton oxidative degradation of water in organic system.
