VOCsVOCs(ads)H2OH2O(ads)光激发步骤TiO2粒子具有能带结构,由充满电子的低能价带(VB)、空的高能导带(CB)和之间的禁带组成,当受到能量超过禁带宽度的光线照射时,价带上的电子被激发跃迁至导带,并在价带上留下相应的空穴(h+),被吸附剂基材高度分散的纳米TiO2可使光生电子和空穴很快从体内迁移至表面,进而参与下一步的反应。TiO2+hTiO2(h++e)VOCs的光催化氧化步骤一般认为[14-15],光生空穴(h+)是一种强氧化剂,能够将吸附在TiO2粒子表面的H2O和OH氧化为羟基自由基(OH),而光致电子是一种强还原剂,能俘获TiO2表面的吸附氧生成超氧阴离子自由基(O2),并进一步通过质子化作用后成为OH的另一个来源,同时也降低了光生电子和空穴的复合概率,提高了反应速率。

LED背光源提高液晶电视能效与传统的CCFL背光源液晶电视不同,LED背光源液晶电视在节能环保上拥有更强大的优势。首先,LED内部驱动电压远低于CCFL,拥有较低的额定功耗和待机功耗;其次,LED背光源使用的材料不含,不会散发有害气体,更加绿色环保。有数据显示,一台32吋CCFL背光源液晶电视的平均功耗为11W左右,而一台同尺寸的LED背光源液晶电视的功耗却低至5W,如果换成大屏幕,这种对比将更加明显。

Mahewsjal等用聚砜类条束式超滤膜处理染料废水,对分子量大于6的有机染料截留率达96%~98%,条束式PVC膜和聚丙烯腈膜与聚砜一样,对染料有较好的截留率。美国杜邦公司用中空纤维膜反渗透装置处理了9种染料废水,溶解固体去除率达8%~95%,染料平均回收率为75%~85%。美国Newjersey州ciba公司染料化工厂对水溶性废水只需RO或NF处理后,每天可回收染料23kg左右,5%~75%的水实现回用,废水处理费用大幅度降低。
