Title:
SLUDGE-ASH-MODIFIED TITANIUM OXIDE-BIOCHAR COMPOSITE PHOTOCATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/016311
Kind Code:
A1
Abstract:
A sludge-ash-modified titanium oxide-biochar composite photocatalyst, a preparation method therefor and an application thereof. The composite photocatalyst comprises titanium oxide, sludge ash and porous biochar, wherein the porous biochar is a carrier, and the titanium oxide and sludge ash are loaded on the porous biochar; calculating according to the total amount of the composite photocatalyst, the composite photocatalyst comprises 20%-30% by weight of titanium oxide, 10%-15% by weight of sludge ash, and the remainder is porous biochar; and the main gain components of the sludge-ash-modified titanium oxide-biochar composite photocatalyst are all from incineration ash and lignocellulosic biomass of byproduct sludge of a wastewater treatment plant. The present invention belongs to the resource utilization of solid waste, and thus effectively reduces the production costs of composite photocatalysts, and has broad market application prospects.
