▎ 摘  要

NOVELTY - A catalyst with ultra-small particles cobalt comprises ultra-small particle cobalt as active component and is uniformly dispersed on graphene carrier. The cobalt has content of 0.5-5 wt.% and grain diameter of 1-5 nm. USE - Catalyst with ultra-small particles cobalt. ADVANTAGE - The product has excellent catalytic activity and good stability at room temperature. The method is simple and easy and exhibits good catalytic performance in degrading aniline waste water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of catalyst with ultra-small particles cobalt comprising mixing 0.5-5 mg/mL cobalt chloride solution and 1-5 mg/mL graphite oxide water solution, freeze-drying to obtain catalyst precursor, calcining under 20% (volume/volume, v/v) argon atmosphere and 80% ammonia at 600-800 degrees C for 1-2 hours, and cooling to room temperature; and (2) application of catalyst with ultra-small particles cobalt comprising adding 30-70 mg/L catalyst to 20-40 mg/L aniline waste water to degrade at 20-30 degrees C for 5-15 minutes.
