After dried, the base was calcined at 600° C. for one hour to obtain a platinum-carrying catalyst.
乾燥後、600℃で1時間焼成し、再生可能な触媒を得た。
The catalyst was exposed to 3% of CO/N2 at a flow rate of 15 L/min at 950° C. for five hours to obtain a durable(*durability-tested? endurance?)platinum-carrying catalyst.
この触媒に950℃において、3%のCO/N2を15L/minの流速で5時間流通させ、再生可能な触媒の耐久品を得た。
A part of the coating layer of the durable catalyst was sampled, and subjected to the CO chemisorption method described in JP-A-2005-164391 to obtain the average diameter of platinum particles, which was 9 nm.
