您要查找的是不是：
- After annealing, Co Pt particles transform from amorphous to fcc CoPt 3 and fct CoPt, and C remains in disorder state. 热处理使Co Pt颗粒从非晶相转向fccCoPt3和fctCoPt稳定有序相 ;C则保持非晶态 .
- After reduction by hydrogen, the monolayer dispersed PtO_2 forms Pt particles smaller than that from PrO_2 phase. When supported Pt particles are oxidized to form PRO_2, it will disperse onto the support as monolayer again. 单层分散在载体上的PtO_2能被H_2还原为分散度很高的金属Pt,当它经使用老化后又能再经氧化转变成PtO_2,这种新生的PtO_2能够再度自发单层分散在载体上。
- It is found that pulse potentiostatic method is a good method to deposit Pt particles and the electrocatalytic activity of Pt-PANi/Pt can be improved by reducing the pulse lasting time. 采用脉冲电位法通过缩短脉冲沉积时间的方法，能够使铂微粒数目增多分布均匀，有效提高铂的催化表面积，制备的Pt-PANi/pt复合电极显示出了较好的催化活性，此方法优于恒电位方法沉积分散铂微粒。
- The charged Pt particles were stabled with electrostatic and steric effect of PDDA and had obvious correlation with pH value of the solution, PDDA polymerization degree and PDDA content. 颗粒的稳定是PDDA长链分子的位阻效应和阳离子的静电效应协同作用的结果，其稳定能力与PDDA的聚合度、PDDA的用量以及反应体系的pH值密切相关。
