▎ 摘　　要

NOVELTY - Graphene-supported catalyst comprises 5-25 wt.% graphene, 20-40 wt.% copper, 10-30 wt.% iron, 5-15 wt.% manganese, 5-15 wt.% zinc, 5-10 wt.% zirconium, 1-4 wt.% cobalt and 0.1-5 wt.% alkali metal or alkaline earth metal. The alkali metal is sodium, potassium, lithium or cesium. The alkaline-earth metal is magnesium or barium. USE - Graphene-supported catalyst for preparing low carbon mixed alcohol from synthetic gas (claimed). ADVANTAGE - The graphene-supported catalyst has good stability, low cost, long service life and high selectivity under mild reaction conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene-supported catalyst which involves: (A) mixing graphite carrier and metal nitrate solution to obtain a suspension; (B) adding alkaline solution to adjust pH to 8-9 for precipitating suspension; (C) heating at 60-90 degrees C; (D) washing precipitate using distilled water until it is neutral; (E) drying precipitate at 80-120 degrees C; and (F) baking precipitate at 350-400 degrees C for 3-6 hours to obtain desired graphene-supported catalyst.
