Synthesis of High Ordered SiO2 Microwires with Bamboo Charcoals as the Template

Abstract

Abstract: The microstructrue of bamboo charcoal was studied through SEM and highly ordered SiO₂ microwires array were synthesized by using sol-gel method with TEOS as the Si resource and bamboo charcoal as the template. SEM, EDX and XRD techniques were used to characterize the products. The results show that the products were highly pure cristobalite SiO₂ microwires with the diameter of 1-2 μm and length over 200 μm, which copied to the structure of micropore precisely. It shows that the micropores of the bamboo charcoal may perform main template function.

Key words: Bamboo charcoal, Template, Microwires, SiO₂
