Method for preparing photocatalyst ceramic by means of potassium tetratitanate whiskers
The invention relates to a method for preparing photocatalyst ceramic by means of potassium tetratitanate whiskers. The method comprises the following steps that 1, the potassium tetratitanate whiskers serve as main raw materials, and after ball milling is performed on the potassium tetratitanate whiskers in a ball mill, surface modification treatment is performed on the potassium tetratitanate whiskers with a silane coupling agent; 2, ceramic slurry is prepared by using the modified potassium tetratitanate whiskers and deionized water, a binder, low temperature glass powder, is added, a pH value is regulated with a NaOH solution, and high-speed stirring is performed in a magnetic stirrer; 3, short-chain amphiphilic molecules are added, and low-speed stirring is performed; 4, high-speed stirring is performed to foam, when big bubbles start to disappear, the high gear is switched to the low gear, and stirring is performed to obtain uniform and fine foam; 5, injection molding forming is performed, moldings are placed in a drying oven to be dried and then taken out after being cooled to the room temperature, and then the moldings are placed in a high-temperature furnace to be fired into porous ceramic according to the set sintering schedule. Due to the fact that catalytic degradation is performed on toxic organic pollutants by means of cheap and clean sunlight, the method for preparing the photocatalyst ceramic by means of the potassium tetratitanate whiskers has the advantages of being efficient, little in secondary pollution, friendly to environment, low in energy cost and the like.
