摘要
以糠醛和纳米TiO2为前驱物制备了TiO2/共轭高分子复合材料NTP,并通过TEM、XRD和UV-Vis等技术对其进行了表征。结果表明,NTP为具有活性基团和不同长度共轭链的高分子,其中聚糠醛与TiO2以Ti-O-C相键合;该复合材料对光的吸收拓宽至整个紫外-可见光区。在自然光照射及空气氧存在的温和条件下,前驱物(mg(TiO2):ml(Furfural)=1:80)经350℃热处理30 mins制得的TiO2/P复合材料于1 min内可将所给定染料废水彻底降解褪色。
The TiO2/conjugated polymer composite material NTP has been synthesized with Nano-TiO2 and furfural as the precursors,and it was characterized by the technologies of TEM,XRD and UV-Vis.The result showed that,NTP was a high polymer with active groups and conjugated constructions,and the conjugated polymer was interlinked to TiO2 by Ti-O-C bond.The Absorption of the composite material was expanded to the entire UV-visible region.Under the mild condition with natural light and air,the given dye wastewater coul...
