     well hexagonally ordered crsba-15 catalysts synthesized by different hydrothermal methods were used, for the first time, for the selective synthesis of benzophenone (bpo) by liquid-phase oxidation of diphenylmethane (dpm) under various reaction conditions. to investigate the leaching of chromium species on the surface of silica networks, the results of original and reusable cr-containing mesoporous silica catalysts were correlated and compared, and the catalytic activity of washed crsba-15(8) was also demonstrated. based on the all catalytic results for this reaction, crsba-15(8) was found to be a highly active and an environmentally friendly solid catalyst and has superior catalytic activity than other cr-containing mesoporous catalysts.
