利用光电子能谱仪(XPS)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)和能量色散谱(EDS)研究了后处理条件(不同酸度的洗液及基底)对电化学合成的Ru(核)-RuO2(壳)(RNCO)纳米颗粒的结构和形貌的影响.结果发现,直接用水洗的RNCO纳米颗粒会在铜基底上组装成线或棒,而在单晶硅基底上没有发生明显的组装行为.在稀盐酸洗涤过程中,RNCO的核壳结构被破坏,并且各自发生聚集和生长,当产物置于硅片上时,RNCO明显分离为RuO2膜和金属Ru颗粒;当产物置于Cu片上时,Ru生长成为方形颗粒,RuO2颗粒黏附其上.在浓盐酸中,RNCO的核壳发生化学反应生成新的钌氧化物相,新物相以膜的形式铺展在硅片上,而在Cu片上呈现角状结晶.
The effect of post-treatment conditions (lotions and substrates with different acidity) on the electrochemical synthesis of Ru (superscript 2 +) was investigated by means of XPS, TEM, SEM and EDS. Nuclear) -RuO 2 (shell) (RNCO) nanoparticles were investigated.It was found that RNCO nanoparticles washed directly with water could be assembled into a wire or rod on a copper substrate and did not occur on a monocrystalline silicon substrate RNHC was obviously separated into RuO2 film and metal Ru particle when the product was placed on the silicon wafer. When the product was placed on the silicon wafer, Ru grows as a square particle and RuO2 particle adheres to the Cu sheet.In the concentrated hydrochloric acid, the nucleus and shell of RNCO react to form a new ruthenium oxide phase, and the new phase spreads on the silicon film in the form of film, In the presence of angular crystal Cu sheet.
