Description

technical field [0001] The invention belongs to the technical field of semiconductor oxide material preparation, in particular to a tin oxide crystal preparation device. Background technique [0002] Tin oxide crystal fiber is a kind of fiber material with polycrystalline structure. Its crystal grain size is nanoscale, generally not more than 50nm, and the fiber length and diameter can be adjusted by spinning conditions. Tin oxide fibers have the characteristics of nanoscale grains, large specific surface area, fluffy fiber appearance and sufficient contact with reactants in catalytic reactions, so they are suitable as catalysts or catalyst supports. Compared with ceramic solid catalysts or granular catalysts, fibrous tin oxide crystal fibers can increase the reaction sites per unit mass and significantly improve catalytic efficiency. Compared with nanopowders or nanowires, fiber catalysts can be completely separated from the reaction phase as a whole due to mutual entangle...
