硫化银制备

1.在90～100℃条件下，将氧化银(Ⅰ)与硫反应生成硫化银(Ⅰ)，当有水气存在时，Ag2SO4也能被过量硫转化为硫化银(Ⅰ)。

2.将硫代硫酸钠与氧化银(Ⅰ)、硝酸银等可溶性银盐反应，可得硫化银(Ⅰ)

3.将可溶性银盐与可溶性硫化物反应，制得硫化银(Ⅰ)

Aqueous synthesis of highly luminescent AgInS₂-ZnS quantum dots and their biological applications.

Nanoscale 5(6) , 2322-7, (2013)

Highly emissive and air-stable AgInS2-ZnS quantum dots (ZAIS QDs) with quantum yields of up to 20% have been successfully synthesized directly in aqueous media in the presence of polyacrylic acid (PAA...

Ag2S-ZnO--an efficient photocatalyst for the mineralization of Acid Black 1 with UV light.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 105 , 314-9, (2013)

The Ag(2)S loaded ZnO (Ag(2)S-ZnO) was successfully synthesized by precipitation of zinc oxalate and Ag(2)S and calcination of the mixed precipitate at 400 °C for 12 h. The catalyst was characterized ...

Highly efficient antiviral and antibacterial activities of solid-state cuprous compounds.

J. Hazard. Mater. 235-236 , 265-70, (2012)

We found that several solid-state cuprous compounds, including cuprous oxide (Cu(2)O), sulfide (Cu(2)S), iodide (CuI), and chloride (CuCl), have highly efficient antiviral activities, whereas those of...
