Room temperature synthesis of novel worm like tin oxide nanoparticles for photocatalytic degradation of organic pollutants

Herein, we report the synthesis of novel worm like structured SnO2 nanoparticles photocatalysts by chemical precipitation route from sodium stannate in the absence of a precipitating agent. The physico-chemical characteristics of the synthesized SnO2 were studied using powder X-ray diffraction (PXRD...
