Abstract:

In order to explore the reaction mechanism of preparing SnO2/C composite materials by biotemplating, multiple samples are prepared by carbothermal-reduction under vacuum from ramie fibers/Sn (OH)4 precursors, which were prepared from ramie fibers impregnated with Sn (OH)4 sol. Thermodynamic calculation and experimental research indicate the reaction mechanism of preparing SnO2/C composite materials is that granular SnO2 is generated by pyrolysis of Sn (OH)4 at about 345.7°C,which distributes in the clearance of the ramie carbon. Pellet-like SnO/SnO2 composites generated by gas-solid and solid-solid reaction is solid solution of SnO and SnO2 in the Sn-O-C-H reaction system. And the microstructure of the composites changes from block to pellet-like with the increase of Sn content. The results show that the temperature of 631.3°C is the critical temperature that the reduction reaction of SnO2 and C can occur spontaneously. With the increase of sintering temperature, SnO2 is reduced to SnO and Sn by agent C and CO, SnO2 in turn. Furthermore, thermodynamic analysis results coincide well with the experiment data.
