Synthesis of TiO2 nanofibers with adjustable anatase/rutile ratio from Ti sol and rutile nanoparticles for the degradation of pollutants in wastewater

摘要: Abstract TiO2 nanofibers with adjustable anatase/rutile ratios were fabricated via a novel method involving electrospinning from Ti sol and rutile nanoparticles. Rutile nanoparticles directly added to the spinning solution. The solution was completely transformed into anatase after calcination, contained phases of different proportions. Although diameter increased adding nanoparticles, their surface roughness because distributed on fiber surface. reduction in electron–hole recombination rates improved photocatalytic activity interactions between phases. 40 min methylene blue (10 mg/L) decomposition rate photocatalyzed by reached 90.7%, although specific area 20 wt% only 20.74 m2/g.
