NOVELTY - Air purifying material comprises carrier material and active metal oxide, where carrier material contains lignin, graphene oxide and lanthanum oxide. USE - Air purifying material used in air purifying agent(claimed). ADVANTAGE - The air purifying material promotes pollutant degradation, improves purifying efficiency of air purifying material and has high efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing air purifying material, which involves preparing corresponding metal nitrate aqueous solution, adding carrier material with adequately stirring for 2-5 hours, adding proper amount of sodium hydroxide solution to form precipitate attached on carrier material at 60-90 degrees C, performing aging for 3-6hours, filtering, washing by distilled water to obtain solid, drying obtained solid at 450-650 degrees C for 4-8 hours to obtain air purifying material; and (2) a air purifying agent, which is used in preparing air purifying material.
