【摘要】 本课题首先制备SrTiO₃光催化剂,然后将SrTiO₃采用以下三种方式载覆于纸张中制备光催化纸:⑴直接加填抄造法制备光催化纸;⑵配制成涂料后,采用涂布法制备光催化纸;⑶将光催化剂与纸浆纤维复合制备光催化复合纤维,再与纸浆纤维混合配抄光催化纸。检测和分析光催化剂在纸张中的留着效果及光催化纸对甲醛的降解效果,比较得出最优的光催化剂载覆方式。结果表明:直接加填纸的留着率为64%,对甲醛的降解率为63.5%;涂布纸的留着率为96%,对甲醛的降解率为70.5%;光催化复合纤维纸的留着率为93%,对甲醛的降解率为73.4%。由此可见,光催化复合纤维配抄法为最佳的光催化剂载覆方式。更多还原

【Abstract】 In this paper, SrTiO₃ photocatalyst was first prepared, and then the SrTiO₃ was loaded on paper in the following three ways to prepare photocatalytic paper.（1） Using directly filling method to prepare the photocatalytic paper;（2） Using the coating method to prepare the photocatalytic paper after the coating being prepared;（3） Combining photocatalyst with the pulp fiber to prepare the photocatalytic composite fiber, and then mixing with the pulp fiber to prepare photocatalytic paper. Measure and analyze the retention effect of photocatalyst in paper and the degradation effect of photocatalytic paper on formaldehyde, and compare to obtain the best photocatalyst loading method. The results show that the retention rate of the directly-filled paper is 64% and the degradation rate of formaldehyde is 63.5%; the retention rate of the coated paper is 96% and the degradation rate of formaldehyde is 70.5%; the retention rate of the composite photocatalytic fiber paper is 93%, and the degradation rate of formaldehyde is 73.4%. It can be seen that the composite photocatalytic fiber papermaking method is the best photocatalyst loading method.更多还原
