摘　　要：选择相溶解技术是一种简单、经济、有效的微/纳结构制备方法,尤其是在超长径比、超深宽比和单晶微/纳结构制备方面具有独特的优势。其原理是提取两相或多相合金中的微/纳结构,尺寸调控主要在预制合金形成的过程中进行。本文在明确区分选择相溶解技术和去合金化的基础上,首次详细综述了选择相溶解技术在纳米颗粒、微/纳丝、微/纳米孔和微/纳通道制备方面的研究进展,并结合本课题组研究工作完善了其工艺流程,拓宽了其应用范围,丰富了微/纳结构种类,为该技术在微/纳结构制备领域的广泛应用奠定了基础。Selective phase dissolution technology is a simple,economical and effective method for preparing micro/nanostructures,especially in the aspect of ultra-long-diameter ratio,ultra-deep-width ratio and single crystal micro/nanostructures.The principle is to extract micro/nanostructures in two-phase or multiphase alloys,and size control is mainly carried out during the formation of prealloys.Based on a clear distinction between selective phase dissolution and dealloying,the research progress of selective phase dissolution in the preparation of nanoparticles,micro/nanowires,micro/nanopores and micro/nanochannel structures were reviewed for the first time.Combined with the research work of our group,the technological process is improved,the application scope is broadened,and the types of micro/nanostructures are enriched,which lays a foundation for the wide application of selective phase dissolution in the preparation of micro/nanostructures.
