چکیده
AgCuS is believed to be an ideal material for diodes or transistors. Because of its relatively low lattice thermal conductivity and narrow band gap energy, also, a strong candidate light- heat-energy harvesting material. Since exhibits superionic like other I–VI group semiconductors, application secondary batteries nanogap switches has been investigated in recent years. In this study, we demonstrated the synthesis nanoparticles (NPs) with size distribution. First, elemental sulfur thioacetamide (TAA), sources reduce distribution NPs. When was used as source, NPs wide were obtained. As oxidized 1-dodecanethiol absorbed onto surface disulfide, passivation layer NPs, which prevents coagulation growth, destructed. Conversely, use TAA source enabled fabrication nearly monodispersed Ar gas flow plays important role NP regular shape. The Ag/Cu molar ratio increased reaction temperature duration time. We confirmed that β–α α–δ phase transitions occurred system. transition 6 nm lower than bulk crystals. Moreover, cation migration via high-resolution transmission electron microscopy. Owing potential gradient induced by focused beam (EB) irradiation, metal ions moved EB irradiation area reduced state. This phenomenon, resembles EB-lithography, could exploited metal/semiconductor nano-heterostructures. can store electrons reduction according Ag+(in AgCuS) + e− = Ag(on AgCuS), they serve cathode materials rechargeable batteries.

متن کاملPolyol Process Synthesis of Monodispersed FePt Nanoparticles.
Monodispersed FePt nanoparticles are synthesized by reduction of iron(II) acetylacetonate and platinum(II) acetylacetonate with 1,2-hexadecanediol as the reducing reagent in the polyol process. As-prepared FePt nanoparticles are chemically disordered with fcc phase. Transmission electron microscopy (TEM) images show a self-assembled particle array with an average particle size of 3 nm and a sta...

An in-situ reduction method has been reported to prepare gold nanoparticles (GNPs) of 40-110 nm by using the green reducing agents of proteins, which are activated by H2O2 and the superoxide anion (). The protein of collagen turns HAuCl4 to the aqueous Au(I) ainions, which are further reduced by other proteins to be highly monodispersed and spherical GNPs of different sizes. The GNPs reduced by...

A chemical reduction method for preparing monodispersed pure-phase copper colloids in water and ethylene glycol has been reported. Owing to the reduction property of ethylene glycol, the reaction rate in ethylene glycol is higher than that in water. In addition, the amount of reducing agent can be reduced largely. Ascorbic acid plays roles as reducing agent and antioxidant of colloidal copper, ...
