金属铂是一氧化碳电氧化的最活泼催化剂。但是,从实用的观点,纯铂的电催化性能不够理想,需要对它进行多方面改性。本工作是关于钌在铂中的助催化功用的研究。 (一)实验部分 仪器设备和实验操作基本同第(Ⅰ)报中所述。 催化剂的制备采用共浸渍法。催化剂的组成:Pt/C按重量比计算,除另有注明外,均固定为5/95;Ru/Pt按原子比计算。 电解液为1NH_2SO_4。催化剂用量为0.03g。文中所示的电位值均相对于NHE。
Platinum is the most active catalyst for carbon monoxide electrooxidation. However, from a practical point of view, pure platinum electrocatalytic performance is not ideal, it needs to be modified in many ways. This work is about the catalytic role of ruthenium in platinum. (A) Experimental equipment and experimental part of the basic operation of the same (Ⅰ) reported. Preparation of the catalyst co-impregnation method. Catalyst composition: Pt / C calculated by weight, unless otherwise specified, are fixed at 5/95; Ru / Pt calculated in atomic ratio. Electrolyte 1NH_2SO_4. The amount of catalyst is 0.03g. The potentials shown in the text are relative to the NHE.
