Abstract

The invention relates to Waugh-type manganese molybdate included in dysprosium-isonicotinic acid. The Waugh-type manganese molybdate has a chemical formula of (NH4)3[Dy(Hina)2(H2O)6][MnIVMo9O32].7H2O. The Waugh-type manganese molybdate is prepared from manganese acetate, dysprosium nitrate, isonicotinic acid, hydrogen peroxide with a concentration of 30%, glacial acetate acid and ammonium heptamolybdate through a reaction in an aqueous solution. The preparation method is simple, easy to operate and low in cost; and crystals are fast in growth and high in yield. Experimental and research results show that the Waugh-type manganese molybdate exerts good photocatalytic degradation effect on azophloxine and provide experimental basis for application of polyoxomolybdate to photocatalytic degradation of organic dyestuffs.

Description

technical field [0001] The invention belongs to the technical field of polymolybdate chemical material preparation, and in particular relates to a preparation method of Waugh-type manganese molybdate containing dysprosium-isonicotinic acid and its application in the photodegradation of organic dyes. The compound utilizes manganese acetate, Dysprosium nitrate, isonicotinic acid, 30% hydrogen peroxide, glacial acetic acid and ammonium heptamolybdate react in aqueous solution. Background technique [0002] Polyacid compounds, also known as polyoxometalates, are composed of high-priced pre-transition metal ions (such as Mo Ⅵ , W Ⅵ , V Ⅴ ,Nd Ⅴ , Ta Ⅴ etc.) are highly polymerized with oxygen to form inorganic polymer clusters with a spatial network structure. Because of their oxygen-rich surfaces, controllable structure, size, compositional and structural diversity, and unique redox activities, they have attracted great attention in the fields of catalysis, fluorescence, magn...
