Continuous microwave flow synthesis and characterization of nanosized tin oxide

We report here the effect of microwave power on the physicochemical and photocatalytic properties of nano-crystalline tin oxide (SnO2) synthesized by using a continuous microwave flow synthesis (CMFS) process. The obtained nanoparticles (Nps) were characterized by using TEM, XRD, FTIR, BET, UV-vis a...
