Carbon Removal From Solgel Products

02/20/2009 3:57 PM

Dear friends

I am working on TiO2-Ge nano materials using solgel route. I am getting the required solgel but with lots of carbon coming from solvents like ethanol, ethlenediamine and ethyl glycol. I dont wants to oxidise the sol so i need some solvent material or gases to remove carbon with out going to high temperatures.

Hi,

all your solvents are volatile, so slowly evaporating would be simplest, elevated temperature will help, flushing with any gas or air also.

Carbon, as a solid, is practically insoluble in most solvents. Carbon in organic compounds can be removed by evaporation, as indicated correctly above, which can be accelerated by increasing the temperature and lowering the pressure. So the method of removal rather depends upon the form the carbon-based impurities are found in and the properties of that material. A Google search will yield loads of useful data on the properties of materials.
