چکیده
|
Polyoxomolybdate [Mo36O110(NO)4(H2O)14]·52H2O was synthesized by a simple one-pot procedure through reducing an acidified mixture of Na2MoO4·2H2O and NH2OH·HCl. In order to create a heterogeneous catalyst system, the polyoxomolybdate was pillared with MgAl-LDH-NO3 by direct ion exchange. These novel materials were carefully analyzed by various chemico-physical methods. The catalytic degradation of methylene blue (MB) and rhodamine B (RB) as common dyes in the presence ofMgAl-LDH–1 nanoparticleswith aqueous hydrogen peroxide,H2O2, as an oxidizing agentwas studied in aqueous solution at roomtemperature.More importantly, the catalyst can be recovered and reused efficiently up to five consecutive cycles with negligible loss of catalytic activity.
