This study presented a new type of monolithic magnetic photocatalytic composite material.Using polyurethane foam as a template,biomass phenolic resin as a carbon source,and FeCl3 as a magnetic source,biomass magnetic foam carbon (MCF) was synthesized.Further,magnetically integrated Fe3O4-CN/MCF composite photocatalytic material was prepared using MCF as the carrier.The composite material had a high specific surface area,high photocatalytic efficiency,and magnetic recovery ability,effectively solving the problem of difficult separation and recovery of traditional powder photocatalytic materials.Moreover,this study explored the effect of Fe3O4-CN loading on the properties of the composite material,and found that the optimum loading amount was 4%.Experimental results showed that the prepared magnetically integrated Fe3O4-CN/MCF composite photocatalytic material had good catalytic performance and stability.After 5 cycles of use,the catalytic performance of the composite system decreased by only about 30%,which was much higher than the degradation ability of single nitrogen-carbon,and exhibited good reusability.This material can be applied in environmental remediation fields such as photocatalytic degradation of organic pollutants,offering broad application prospects.
