Zusammenfassung:	The invention discloses an environment-friendly nano material gamma-Fe2O3 for automobile tail gas nitric oxide catalysis purification and a preparation method of the environment-friendly nano material, and belongs to the technical field of environment-friendly purification material preparation. The environment-friendly nano material comprises gamma-phase Fe2O3 particles, and the sizes of the particles are within 23-228 nm. The preparation method comprises the following steps: by taking iron wires which are smooth and clean in surface as a raw material, putting the iron wires into 80 mL of a mixed solution, wherein the mixed solution comprises 5-15 mL of absolute ethyl alcohol, 33.6g-44.8g of KOH and the balance of deionized water; performing hydrothermal reaction for 24-48 hours at 270-290 DEG C, further performing ultrasonic treatment for 9-20 hours, filtering, soaking and stirring for 2-5 hours in a 10-25% ammonium hydroxide solution, and further soaking and stirring for 1-6 minutes in a 2-6% hydrochloric a
