Silver (Ag) was loaded on TiO 2 powders through mechanical ball milling. Ag-loading was accomplished by adding 4.6, 9.2, and 13.8 ml of AgNO 3 solution to the TiO 2 powders during the milling process. The resulting powder was characterized by XRD, XPS, SEM, and EDS. The photocatalytic activity of the silver-loaded powder was evaluated in terms ...

A planetary ball mill was employed to reduce the particle size of TiO2 powders to nanoscale and silver loading to TiO2 powders. Silver nitrate was used …
Silver (Ag) was loaded to three different kinds (P-25, NT-22, and TiO(OH)2) of titanium dioxide (TiO2) powders through adding three different quantities (4.6, 9.2, and 13.8 ml) of silver nitrate (AgNO3) solution by mechanical ball milling process.
Graphite flake was obtained from Alpha Aeser having a purity of 99% and the average particle size of 10 µm as shown in Fig. 1c. Copper (named Bm-Cu), Copper-2 wt% Graphite flake (named Cu-GF), Copper-5 wt% Silver (named Cu-Ag), Copper-5 wt% Silver-2 wt% Graphite flake (named Cu-Ag-GF) mixtures were subjected to ball milling for 40 h. In ...
When the ball milling ended, the silver powder was separated from slurry and washed with alcohol for three times, then dried at 60 C in vacuum oven for 12 h. 2.2 Characterization The micrographs of the milled powders were determined by a Hitachi S-4800 scanning electron microscope (SEM)
Silver nanoparticles play a significant role in health management due to their wide range of applications as antimicrobial agents, antitumour agents and in food packing, in agriculture and in the healthcare sector. Furthermore, it is well known that most of the empirical use of antibiotics exhibits resistance leading to ineffectiveness.
metal silver, usually in the form of a sulfide. When silver is present in sufficient quantities, galena is regarded as a silver ore and called argentiferous galena. Sphalerite is zinc sulfide, but may contain iron. Black sphalerite may contain as much as 18 percent iron. Lead Ore The lead produced from lead ore is a soft, flexible and ductile ...
