▎ 摘 要
NOVELTY - The platinum single atom catalyst is composed of boron-doped or boron-nitrogen-doped substrate on which platinum atom catalyst is loaded in single atom state. The substrate is composed of graphene, conductive carbon black, acetylene black graphite multi-wall carbon nano-tube, and nano-carbon fiber platinum element occupying mass percentage in range of 0.01 to 3.5 percent. USE - Platinum single atom catalyst used for electrocatalysis ozone precipitation reaction. ADVANTAGE - The platinum single atom catalyst having high catalytic activity and stability is operated in environment-friendly manner with reduced dosage of platinum noble metal, thus improving utilization rate of noble metal and reducing use cost of noble metal platinum. The catalyst is provided with high ozone precipitation efficiency and high load rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparation of platinum single atom catalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view showing the composition of platinum single atom catalyst. (Drawing includes non-English language text)
