3和NaOH反應(yīng)生成Ag2O納米簇，然后加入還原劑甲醛，在Ag2O模板表面形成Ag納米殼，副產(chǎn)物CO2則在Ag殼內(nèi)聚集。隨著反應(yīng)的進(jìn)行，不斷增大的壓力最終擊穿Ag殼，形成了直徑約為200 nm的Ag納米碗。該方法為特殊結(jié)構(gòu)貴金屬納米材料的研究提供了理論和實(shí)驗(yàn)基礎(chǔ)。;The silver nanobowls were prepared by self-template method, and the structure and growth mechanism of Ag nanobowls were investigated. Results show that the Ag2O clusters result from the reaction of AgNO3 and NaOH. After adding the reductant methanal, Ag nano-shell is obtained on the Ag2O cluster surface with the by-product CO2 inside the Ag nano-shell. With the reaction further proceeding, the increasing pressure breaks through the Ag nano-shell, thereby forming the Ag nanobowls with the size of approximately 200 nm. This unique synthesis method provides theoretical and experiment basis for the noble metal nanomaterials with special structure."/>
