【摘要】：以乙酰丙酮鈀為前驅(qū)體,聚乙烯吡咯烷酮(PVP)為穩(wěn)定劑,N,N-二甲基甲酰胺(DMF)為溶劑,一氧化碳為還原劑,在一定量甲酰胺的存在下,控制CO的流速,100℃油浴加熱3 h,可以得到形貌單一的四角枝狀Pd納米晶,單枝呈多級(jí)結(jié)構(gòu)特征。利用透射電子顯微鏡(TEM)、掃描電子顯微鏡(SEM)、X-射線粉末衍射(XRD)、X-射線光電子能譜(XPS)對(duì)其結(jié)構(gòu)進(jìn)行表征。所合成的多級(jí)四角枝Pd納米晶對(duì)甲酸的電催化氧化活性約為商業(yè)Pd黑的2.6倍。
[Abstract]:Using palladium acetylacetone as precursor, polyvinylpyrrolidone (PVP) as stabilizer, (DMF) as solvent, carbon monoxide as reducing agent, and in the presence of formamide, The single tetragonal dendritic Pd nanocrystals can be obtained by controlling the flow rate of CO at 100 鈩，
