متن کاملSelective Catalytic Reduction of CuO/SiO2 Nano-composites towards NO Reduction in Gas-phase
The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7.
