Abstract

The invention relates to a preparation method of a load type metal compound catalyst used for water treatment, in particular to a catalyst comprising a metal oxide and metal salt. The method comprises the following steps: a porous inorganic material carrier, metal salt, a dispersant, a stabilizing agent and a accelerant which are treated are added into an organic solvent and stirred to form a load type catalyst before-preparation body mixture, the load type catalyst before-preparation body mixture stands for 1 to 9 days under a sealed condition until the load of the catalyst is completed, a steady load type catalyst before-preparation body is prepared, put in a baking oven for baking, moved into a muffle furnace and heated to 300 DEG C to 600 DEG C under air atmosphere at the speed of 2 DEG C/min to 6 DEG C/min, the temperature is kept for 1 to 8 hours, and finally, the load type metal compound catalyst used for water treatment, which forms a fixed catalyst layer with the layer thickness of 15nm to 28mum on the surface of the carrier, is prepared. The method has lower cost, little loss of raw materials in the preparation technology process and simple preparation technology, and is suitable for industrial mass production.

Description

technical field [0001] The technical solution of the present invention relates to a catalyst containing a metal compound, in particular to a preparation method of a supported metal compound catalyst for water treatment. Background technique [0002] Catalytic oxidation catalysts have a strong ability to donate electrons, which can separate electrons from holes (carriers) and migrate to different positions on the surface of particles. In the process of water treatment, they can accelerate the decomposition of organic matter in water. Reaction; catalytic oxidation catalyst itself has a strong ability to obtain electrons, which can capture electrons from organic substances contained in water to activate and oxidize substances, thereby completely catalytically converting organic substances in wastewater into inorganic substances. [0003] CN 99102734.5 discloses a method for preparing a supported titanium dioxide photocatalyst, and proposes a method for preparing a photocatalyst...
