The invention discloses a preparation method of a
halloysite loading
phosphoric acid Silverlight catalyst. The preparation method comprises the following specific steps of adding
halloysite in a salpeter solution so as to obtain the
halloysite after
acid treatment, placing the 4-8g halloysite after
acid treatment into a vacuum
filtration bottle, mixing the halloysite and a
silver nitrate ethanol solution under a
vacuum state, enabling the
silver nitrate to fully enter a halloysite
pipe, sequentially stirring 2-5h, carrying out
solid-liquid separation, and
vacuum drying at 70-80 DEG C; adding the obtained product after
drying in a 50 mL of
sodium dihydrogen
phosphate solution the concentration of which is 0.5-1.5mol / L, stirring for 4-5h, carrying out
solid-liquid separation, washing,
drying at 100-105 DEG C so as to obtain the halloysite loading
phosphoric acid Silverlight catalyst. The preparation method provided by the invention has the advantages that the air and
moisture in a halloysite pipeline are discharged, the
silver nitrate enters a pipeline, an aluminum
oxide of the inner wall of the halloysite is removed, the effects of increasing light penetrating degree and aperture property action can be achieved, the obtained
silver phosphate particles are arranged in a halloysite
pipe and are prevented from birdnesting and falling.
