Example Sentences:

	1.	At last , the effects on the electrocatalysts by pretreatments of carbon support , dispersant and precursor are studied 重点分析了碳载体的氧化预处理、分散剂、前躯体对冷冻干燥法制备pt / c催化剂的影响。
	2.	Through the comparison between freeze - drying and heat - drying , the agglomeration and the desorption of the precursor on carbon support can be alleviated with freeze - drying method . the effects on the electrocatalysts by pretreatments of carbon support , dispersant and precursor are studied . the result shows that pretreatment of the carbon support by kmno _ 4 can add oxygen - containing functional groups on the surface of carbon , which can reduce the hydrophobicity of the carbon support , and then make it much easier for carbon to dissolve in water to form suspension ; isopropyl alcohol can make the carbon support in high dispersion in the precursor solution , which can make the precursor absorbed on the surface of the carbon 采用高锰酸钾氧化预处理的碳载体比表面积较大,表面含氧官能团数量较多,亲水性较好,有利于前躯体在碳载体表面的吸附;选取异丙醇作为预冻液中的分散剂,有利于碳载体在前躯体溶液中的分散,容易实现前躯体离子在碳载体表面的稳定吸附和分散;使用酸性pt ( no _ 2 ) _ 2 ( nh _ 3 ) _ 2作为前躯体,可以使前躯体离子和碳载体表面的酸性含氧官能团发生离子交换反应,使得前躯体离子吸附量增大,分散更加均匀,以上三种因素的选取都可以得到催化活性更高的pt / c催化剂。
	3.	The ratio of isopropyl alcohol and pure water and temperature in the process of freezing are considerated in the research of the preparation of the pt / c electrocatalysts with freeze - drying method . the result shows , when we use 300ml pure water to wash the carbon ( 40mg ) in isopropyl alcohol ( 20ml ) to alter the ratio of isopropyl alcohol and pure water , we get the electrocatalysts with high catalytic activity ; the use of the liquid nitrogen ( - 196 ) to freeze the suspension ( carbon and precursor solution ) can make the pt / c electrocatalysts in high dispersion 采用300ml纯水对20ml异丙醇中的40mg碳载体进行洗涤抽滤,来改变预冻液中的醇水比例,通过冷冻干燥制备pt / c的性能较好;采用液氮对预冻液进行冷冻(预冻温度为- 196 )制备的pt / c催化剂性能较好;冷冻干燥法可以有效地避免加热干燥过程中前躯体离子在碳载体表面的脱附和团聚,进而制备载量大、分散性好、粒径较小的pt / c催化剂。
