Tin dioxide (SnO2) is a well-known catalytic material used to catalyze different organic dyes and gas sensors.Similarly, it is also considered a good sensing and optoelectronic material.In this work, SnO2 has been synthesized using a microwave-assisted continuous flow method.The effect of dwell time was utilized to study its effects on the physical properties of SnO2.X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Transmission Electron Microscopy (TEM) and tillman 750m Bruner Emmit-Teller (BET) techniques were used to characterize the synthesized SnO2.

UV-Visible spectroscopy technique was employed to calculate the energy bandgap, which weboost splitter exhibited a decrease in the energy bandgap from 3.44 to 3.33 eV on increasing the dwell time.XRD results exhibited an increase in the degree of crystallinity from 56 to 63% and a reduction in the particle size from 3.74 to 2.

75 nm.Where, BET study revealed a shrinkage in the surface area from 159 to 154 m2g-1.Photoluminescence (PL) study was conducted to investigate the surface defects.Photocatalytic efficiency of the SnO2 was probed against the photodegradation of methylene blue dye and this study revealed that SnO2 is a good photocatalytic material.
