Abstract:With urea as the N source, the N-TiO2 was prepared by doping and modifying TiO2. Firstly, cellulose solution and N-TiO2 were mixed, and then the photocatalytic composite fibers were prepared by electrospinning. Finally, the photocatalytic composite fibers were mixed with pulp fibers to prepare photocatalytic paper for degrading formaldehyde. The results showed that the prepared photocatalyst N-TiO2 had small particles, could be uniformly dispersed in pulp fibers, and easily spun into photocatalytic composite fibers with cellulose solution. The prepared photocatalytic paper had the degradation rate for formaldehyde of 53.8%, the tensile index >41.9 N·m/g and burst index >2.03 kPa·m2/g, with good strength properties. |
