Synthesis of Mesoporous MgO Nanostructures for Enhanced Adsorption and Antimicrobial Application

Abstract

MgO was synthesised via surfactant-templating method. Different ratios of mixture of surfactants were used to increase the surface area. Highest surface area was recorded with C16TAB:SDS was 179.81 m2g-1. Synthesised sample were characterised by FTIR, SEM, XRD, TEM, and BET. The adsorption study and antimicrobial activities was done. The maximum adsorption capacities were (333.33, 250 and 200) mg g-1 for methylene blue, alizarin and rhodamine, respectively. MgO also has a very good use as a bactericide. The antimicrobial activity of MgO was also checked on E.coli and B.Subtilis and their IC50 values obtained after 24h were 0.476±0.056 and 0.449±0.043, respectively.
