Abstract

A preparation method and an application of a tailings-based zeolite@carbon dots-titanium dioxide (CDs-TiO) composite photocatalyst are provided, which relates to the field of solid waste utilization technologies. The preparation method includes performing an acidification treatment on tailings powder and then roasting to obtain modified tailings powder; adding the modified tailings powder and titanium dioxide into lye to obtain mixed suspension; stirring and aging the mixed suspension under ultraviolet irradiation to obtain an aged suspension, performing a hydrothermal reaction on the aged suspension to obtain a product, filtering, washing and drying the product to obtain the tailings-based zeolite@CDs-TiOcomposite photocatalyst. The tailings-based zeolite@CDs-TiOcomposite photocatalyst is used to degrade methylene blue, and the photocatalyst is used to treat an organic pollutant in water, which has advantages including a shift in response wavelength and a high photocatalyst activity, and the composite photocatalyst can be applied in an environmental protection field.
