Assessment of the superior photocatalytic properties of Sn-containing SnO microrods on the photodegradation of methyl orange.

A microporous Sn-containing SnO material presenting microrod morphology and a surface area of 93.0 m g was synthesized via a simple hydrothermal route. Sn ions were detected in the interior of the material (15.

Application of mesoporous SBA-15 silica functionalized with 4-amino-2-mercaptopyrimidine for the adsorption of Cu(II), Zn(II), Cd(II), Ni(II), and Pb(II) from water.

This work reports the sol-gel synthesis of a SBA-15 silica, and its functionalization with 4-amino-2-mercaptopyrimidine to perform adsorption of metal species from aqueous media. The functionalization of the material was confirmed by FTIR and superficial area measurements. The final material was tested through batch experiments to uncover its adsorptive properties towards the adsorption of Cu(II), Cd(II), Zn(II), Pb(II) and Ni(II).
