英文摘要	采用简单的热扩散法,MoO3可在模板纳米孔道内有序生长,经还原后获得MoO2和金属Mo纳米管/线阵列.运用XRD、SEM、TEM、HRTEM等技术对产物进行了表征.结果表明:在70 nm孔径的阳极氧化铝模板上,H2/N2气氛下600℃时的还原产物为单晶MoO2;而在50 nm的模板上,同样条件的还原产物为MoO2微晶聚合体.乙醇的加入能够大大改善产物的形貌.H2气氛,650℃以上温度下进一步还原得到了金属Mo纳米管阵列.; MoO2 nano-arrays were simply prepared by reduction of thermally diffused MoO3 on anodic aluminum oxide(AAO) template. The structure and morphology of the nano-arrays were studied by XRD, SEM, TEM and HRTEM. The results showed that, after hydrogenation of the evaporates under 600degreesC in H-2/N-2 mixture, single crystalline MoO2 nanotubes/narowires were produced on 70 nm AAO template, while on 50 nm AAO template yielded was the piling-up Of MoO2 nanocrystallites in nanotubes. Addition of ethanol into the powdered MoO3 precursors greatly improved the morphology of the nanowires. Further reduction Of MoO2 at above 650 degreesC in H-2 led to the production of Me nanotube arrays.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000222223400017&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 5; 06; 637-641; 20
