size degradation
1.Nanosized titania(TiO2) with particle size less than 10 nm has been prepared by low _ temperature thermolysis. The photocatalytic degradation of o _ nitrophenol and 2,4 _ dinitrophenol with prepared TiO2 was studied using UV light source at 254 nm.
2.Nanometer TiO 2 was prepared with TNB as raw material by sol gel process. The particle was well distributed in Ni P plating layer on steel surface by electroless plating and its size was ～30 nanometer in diameter. The compound plating layer behaved like TiO 2 powder in the effect of photocatalytic degradation for methylene blue.
3.The research indicates that preferable result of stalk degradation is procured and degradation-rate of cornstalk cellulose and hemicellulose are got up to 70% at least, when the conditions are microorganisms group by TR-1 and CB-3 and SC-6,10 d of reaction time, 30℃ of reaction temperature, and 0.12 ml/g of inoculums size.
