Aerogel nanocomposites of ZnO-SnO2 as efficient photocatalysts for the degradation of rhodamine B

For the first time, aerogel nanocomposites containing ZnO and SnO2 were successfully prepared through a facile, sol-gel method without the use of a template or supporting matrix. These nanoparticles exhibit high potential for application as a photocatalyst for wastewater remediation.
