Tungsten was incorporated into silica matrix using sodium silicate from rice husk at pH 10, 7 and 3. These catalysts were labeled as RHW-10, RHW-7 and RHW-3. The pH was found to have a strong influence on the structure of the resulting silica–tungsten species and its catalytic activity. Analysis sug...
