摘　　要：制得表面修饰纳米γ-MnS,表征了其组成和结构,指出产物分子以络合结构形式存在。产物有较好热稳定性和化学稳定性,且粒径小,分布窄,分散性好。其UV-V is吸收峰有"蓝移"现象,表明其量子尺寸效应,为新型纳米光电化学催化剂的开发奠定了基础。Surface-modified γ-MnS nanoparticlcs were synthesized by the method named as ‘Colloid Chemistry Assistant Solvothermal Technique＇. γ-MnS nanoparticlcs were characterized byA facile synthesis method to fabricate ultra-dispersed transition metal sulfide nanoparticles was developed . This method was named as ‘ Colloid Chemistry Assistant Solvothermal Technique＇. Surface-modified γ-MnS nanoparticlcs were synthesized by this technique. The MnS nanoparticles were protected by organic （xianan） that showed complexation structure in the combination with the metal nanoparticles. Having characterized asformed products＇ molecular compositions and structures and indicated its complexation structure. The product had good thermal-stability and chemical-stability with good dispersion in considerable small particle size and narrow distribution. The blue shift of the indicated The quantum size effect of metastable MnS nanocrystals was observed with a blue shift of UV-Vis absorption edge. The experimental results provided in this article are meaningful for developing new photoelectrochemistry nanocatalysts.
