Abstract

The invention provides a preparation method of copper pyrophosphate with catalytic activity. The method comprises the following steps: uniformly mixing a copper salt solution with a phosphate solution, then adding an acid solution into the mixed solution to completely dissolve the precipitate, and then drying and calcining to obtain the copper pyrophosphate with high purity and catalytic activity. The prepared copper pyrophosphate has very high catalytic activity, and various organic pollutants (phenol, methyl orange, rhodamine B, formic acid and the like) can be degraded by utilizing the copper pyrophosphate to catalyze hydrogen peroxide. The copper pyrophosphate is simple in preparation process and wide in raw material source, so that the prepared copper pyrophosphate serving as the catalyst for degrading the organic wastewater has very high practical application value.

Description

technical field [0001] The invention belongs to the field of catalyst preparation, in particular to a preparation method of copper pyrophosphate with catalytic activity. Background technique [0002] The chemical formula of copper pyrophosphate is Cu 2 P 2 O 7 , is a light green powder, insoluble in water, soluble in acid and excess sodium pyrophosphate solution (due to the formation of complex ions between copper ions and pyrophosphate ions). Copper pyrophosphate is mainly used in cyanide-free electroplating and is the main raw material for preparing copper plating solution. It is widely used in pyrophosphate copper plating, bronze plating, copper tin alloy plating, etc. Pigments and catalysts, etc. [0003] At present, the preparation method of copper pyrophosphate is mainly formed by the mixed reaction of sodium pyrophosphate solution and copper sulfate solution. Invention patent CN1745895A discloses a catalyst for oxidizing cyclohexane with oxygen and a preparation ...
