The oxidation of styrene by chromium–silica heterogeneous catalyst prepared from rice husk

Chromium was incorporated into the silica matrix extracted from rice husk in basic, neutral and acidic medium. The prepared catalysts were labeled as RHCr-10, RHCr-7 and RHCr-3 according to their pH. The specific surface area of RHCr-10, RHCr-7 and RHCr-3 was determined to be 144, 143 and 564 m2 g−1...
