Problems solved by technology

However, the pre-treatment of graphene is relatively complicated, and often requires the use of toxic oxidizing agents and reducing agents. Other preparation methods need to adjust the pH value of the solution, microwave heating, etc., which increases the production cost and limits its practical application.

Abstract

A preparation method of a rod-like bismuth phosphate loaded biomass carbon aerogel material belongs to the technical field of material preparation and photocatalytic environmental pollution control. The preparation method comprises the following steps: removing skin and bladder of a white gourd, and preparing biomass carbon-based wet gel according to a hydrothermal method without adding any surfactant. The prepared rod-like bismuth phosphate loaded biomass carbon aerogel material is 0.3 to 0.5 [mu]m in diameter, and has such a photocatalytic degradation effect on a simulative dyeing wastewater methylene blue solution that the degradation rate of methylene blue in a 10 mg/L methylene blue solution can reach up to 90 percent when the bismuth phosphate loaded biomass carbon aerogel material is added into the methylene blue solution and the mixture is exposed in visible light for 3.5 hours, so that the rod-like bismuth phosphate loaded biomass carbon aerogel material can be applied to the field of dyeing wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of material preparation and photocatalytic environmental pollution control, and in particular relates to a preparation method and application of a rod-shaped bismuth phosphate-loaded biomass carbon airgel material photocatalyst. Background technique [0002] In today's world, the global energy crisis and environmental pollution are becoming more and more serious, and the sustainable development of human society is facing huge challenges. Semiconductor photocatalytic technology has important application prospects in the field of environmental pollution control, while traditional photocatalysts have quantum However, due to the disadvantages of low efficiency and low utilization rate of solar energy, the development of new photocatalysts has attracted extensive attention of researchers. [0003] Bismuth phosphate is a commonly used photocatalyst, and there are related studies on the compounding of bismuth phosp...
