Effect of synthesis media pH and gel separation technique on properties of copper incorporated SBA-15 catalyst

Cu-SBA-15 catalysts were synthesized hydrothermally under acidic and slightly higher acidic conditions via solid separation by either gel filtration or evaporation. XRD (X-ray diffraction) patterns and HRTEM (high resolution transmission electron microscopy) images showed that metal loading caused l...
