Catalase activity of natural and synthesized on technical cellulosesilicon dioxide

The influence of the properties of natural and synthesized silicon dioxide on technical cellulose from rice and oat husks on the catalase activity of dioxidecontaining materials is estimated. Technical cellulose from the husk was obtained by the oxidative-organosolvent method. The fixation of silicon dioxide on cellulose was carried out by the sol-gel method using tetraethoxysilane. The properties of the obtained dioxide-containing materials were investigated by X-ray diffraction analysis, nitrogen thermal desorption method, inductively coupled plasmaemission spectroscopy. The catalase activity of the dioxide-containing materials was evaluated by the model reaction of Н₂О₂ decomposition. In the course of the work, the following samples of cellulose were obtained: one from rice husks with an ash content of 0.3 to 33.5%; one from oat and rice husks without mineral components. The sol-gel method was used to obtain materials with a content of synthetic silicon dioxide from 0 to 47.2% based on rice husk and from 0 to 44.3% based on oat husk. It was established that the amount of fixed silicon dioxide by the sol-gel method does not depend on the origin of the technical cellulose. The silicon dioxide remaining in the technical cellulose is in an amorphous state. The maximum specific surface area (20.4 m²/g) is achieved at the limiting silicon dioxide content (30.3%). The silicon dioxide synthesized on technical cellulose by the sol-gel method is in a crystalline state, with the maximum specific surface area being 18.5 m²/g for a dioxide-containing material based on OH, and 15.7 m²/g for a dioxide-containing material based on RH; It was found that dioxide-containing material with natural silicon dioxide possesses the catalase activity. This catalase effect can be explained by the presence of impurities in the form of metals, which are accumulated in the mineral component of plant raw materials during the vegetation. Cellulose samples with synthesized silicon dioxide do not have catalase activity, independently from specific surface area and SiO₂ content.
