英文摘要： Controllable fabrication of the supported metal sulfide nanoparticle catalyst is one of the key research subjects in the field of catalysis. However, it is a challenge to fabricate metal sulfide nanoparticles with controllable size, shape and crystallinity. And it is another challenge to achieve synergistic catalytic effect between metal sulfide nanoparticles and supports. In this project, we have proposed to prepare metal sulfide nanoparticles on the surface of electrospun conducting polymer nanofibers by using the dopant of mercapto carboxylic acid as the sulfur source. Herein, we will discuss the nucleation and growth of metal sulfide nanoparticles on the surface of conducting polymer nanofibers, and investigate the effects of the kinds of conducting polymers, the structures of mercapto carboxylic acids and the reactive temperature on the size, composition, morphology, crystallinity of the metal sulfide nanopaticles. In addtion, we will study the enzyme catalytic and photocatalytic properties of the conducting polymer/metal sulfide composite nanofibers. The effects of the size, composition, morphology, crystallinity of the metal sulfide nanopaticles and the interactions between the metal sulfide nanoparticles and the supports on the catalytic performance will be fully investigated. The effects of the carbon coating and noble metal nanopaticles deposition on the catalytic performance will be also studied in detail. We think that this approach developed in this project will help us prepare new kinds of supported metal sulfide catalysts with a superior catalytic performance.
