In order to obtain efficient,low-dimensional,low-cost,easily obtainable,and practical photocatalytic materials,biomass doped titanium dioxide powder particles were prepared,characterized by XRD,SEM and XPS etc.,and utilized in the decolorization of Rhodamine B and the degradation of biomass simulated leaching solution.The results showed that the prepared photocatalyst was a low dimensional,pluralistic and environment-friendly nanoparticles (average particle size <50nm) with good dispersion and low cost,which were conducive to solar energy utilization,co-photolysis of complex organic compounds and environmental pollution treatment.Compared with the undoped samples,biomass doping increased the particle size,specific surface area,roughness,complex internal bonding structure,variety crystalline coexisting and oxygen cavity,which were more conducive to the co-adsorption and photodegradation of organic mixtures.When xenon lamp was used as light source for photocatalytic oxidation degradation,RhB decolorization rate could reach 98.06%,and the pollutant degradation rate in simulated biomass leaching solution could reach more than 85%.It was also found that neutral or acidic environment was more favorable to the photocatalytic effect.Application in environmental self-purification system could promote the industrialization of this technology.
