The utilization of rice husk silica as a catalyst: review and recent progress

In this review article, we report the recent development and utilization of silica from rice husk (RH)for the immobilization of transition metals and organic moieties. Silicon precursor was obtained in the form of sodium silicate and as rice husk ash (RHA). Sodium silicate was obtained by direct sil...
