制备工作电极：分别将10 mg所制备好的催化剂、100 μL去离子水、800 μL无水乙醇、100 μL Nafion溶液5 wt放入5 mL样品瓶分散液超声1 h制备得到墨水匀浆。在红外灯照射下滴涂50 μL 墨水4次共200 μL在1×1cm2碳纸上得到干燥的负载催化剂量为2 mgcm2的碳纸。翻译成专业的学术英语

Preparation of working electrode: The catalyst prepared in an amount of 10 mg, 100 μL deionized water, 800 μL anhydrous ethanol, and 100 μL 5 wt.% Nafion solution were separately placed into a 5 mL sample bottle to disperse the mixture ultrasonically for 1 hour, resulting in a well-dispersed ink. Under infrared light irradiation, 50 μL of the ink was drop-coated onto a 1×1 cm2 carbon paper four times, totaling 200 μL, to obtain a dried loading of 2 mg/cm2 of catalyst on the carbon paper.
