Synthesis and characterization of metal and metal oxide sponges using Triton X-165 as sacrificial template
نویسنده
چکیده
Silver, gold and copper oxide sponges have been synthesized via thermal treatment using Triton X–165 as sacrificial template. Scanning electron microscopy, X-ray diffraction, Thermogravimetric analysis and Brunauer–Emmett-Teller adsorption isotherms techniques are used to characterize the monoliths. Additives like dextran, silica nanoparticles and 1,3,5 trimethylbenzene significantly affect the pore size of the monoliths from 50 nm to 50 μm. The surface area of Au/Triton X-165 / dextran monolith has been determined to be 8.26 m/g, which is greater than that of any pure metal.
