    摘要:

    采用電紡絲法制備了金屬鉑(Pt)與氧化鎳(NiO)復(fù)合納米纖維,并利用XRD、SEM、TEM、半導(dǎo)體分析儀表征了其晶體結(jié)構(gòu),微觀形貌和電導(dǎo)率等性能。研究結(jié)果表明,Pt/NiO納米纖維具有很高的長徑比,表面比較粗糙。加入的氧化鎳抑制了串珠的形成,并維持了一維材料連續(xù)的結(jié)構(gòu)。Pt/NiO納米纖維電導(dǎo)率約為5.95×102 S/cm,這說明鉑納米顆粒在復(fù)合材料中構(gòu)成了穿插的連續(xù)網(wǎng)絡(luò)。

    Abstract:

    Pt/NiO nanofibers were prepared by electrospinning followed by calcination. The crystal structure, morphology and electrical conductivity of the nanofibers were investigated by XRD, SEM, TEM and semiconductor analyzer, respectively. The results show that rough, continuous and uniform nanofibers were successfully fabricated with full removal of inner cores. Adding NiO to Pt nanofibers is beneficial for the sake of maintaining the continuous structure and avoid the bead formation. The prepared Pt/NiO nanofibers have a conductivity of 5.95×102 S/cm, strongly indicating Pt nanoparticles formed continuous networks in the composite structure.
