Further activated carbon was loaded with Mg 2 SnO 4 nanoparticles in order to enhance the photocatalytic performance. Photocatalytic performance of Mg 2 SnO 4 nanocubes and activated carbon loaded Mg 2 SnO 4 nanocomposites were examined by methyl green and methylene blue dye degradation under the exposure of UV light. However, results suggest that activated carbon loaded Mg 2 SnO 4 nanocomposites has significantly enhanced the photocatalytic performance over Mg 2 SnO 4 nanocubes. It is assumed that better photocatalytic activity is caused by the higher specific surface area of activated carbon loaded Mg 2 SnO 4 nanocomposites. Furthermore, cyclic voltammetry was used to analyze the electrochemical properties of the samples. Results indicate that activated carbon significantly enhanced the electrochemical properties of Mg 2 SnO 4 nanoparticles.

Results showed that EWE-AgNPs act as remarkable antimicrobial agent against several Gram- Positive and Negative HPB strains. Maximal growth inhibition zone in Salmonella typhimurium (NCIM 2501) and a minimal inhibition zone in Bacillus subtilis (NCIM 2920) were observed at concentration of 80μg mL -1 . High activity of photocatalytic degradation of methylene blue (MB) at about 94.67% was observed under UV-light irradiation when the reaction time was extended 30 min. The multi-functionality of EWE-AgNPs may be useful for many industrial applications such as catalysis to waste water treatment in near future.
