水稻秸秆中硅体的光催化活性研究
PHOTOCATALYTIC ACTIVITY OF SILICA BODIES IN RICE STRAW
摘要
Abstract
Silica bodies were prepared from rice straw using desiccation-ignition-calcination method, and the prepared silica bodies characterization and photocatalytic ability were studied. It was found that the silica bodies were composed of amorphous micro and nano silica particles, presented Light-driven Dehydrogenase-like Activity （LDA） and photocatalytic activity for the degradation of methyl violet. Triphenyhetrazolium chloride （TTC） was quickly catalysed to water-insoluble Triphenylformanzan （TPF） by silica bodies under the artificial sunlight, valve of the LDA was high up to 2622p, g TPF. g-1. min-1; The results of photocatalytic degradation of methyl violet showed that photocatalytic degradation rate of methyl violet could reach 94.4% in the present of silica bodies after 2h photocatalytic reaction. The study provides a new way for the development and utilization of biomass resources, meanwhile, offers new ideas to researches about the structure and function of biomaterial in natural.关键词
