style=\"color:red\">集料</span>表面,然后将负载型催化剂整体引入到水泥基体中的催化剂应用方法,发现该法能有效提升TiO2催化剂在水泥基材料中的催化效率和耐久性.微米级活性粉煤灰具有良好的水泥基材料兼容性,通过采用简单的碱激发手段,可形成孔径小于50 nm的介孔和微孔类沸石材料,从而影响光催化材料的催化性能.因此,基于粉煤灰的特征,为了进一步提高TiO2催化剂在水泥基材料中的应用效率和催化耐久性,我们采用碱激发法获得了大比表面和介孔结构的沸石类粉煤灰材料,将其用于负载纳米TiO2催化剂,然后引入到水泥基体中,制备了沸石类粉煤灰/TiO2光催化水泥基材料,同时研究了光还原Ag修饰对沸石类粉煤灰/TiO2光催化水泥基材料的催化性能影响及其催化耐久性.结果表明,具有分级孔结构的沸石粉煤灰载体可有效提升纳米TiO2光催化剂在水泥基体中的暴露度,同时还增加了其对气相苯(200×10–6初始浓度)的光催化去除能力.最佳Ag修饰量(1.4×10–4 wt%)沸石类粉煤灰/TiO2光催化水泥样品对气相苯的光催化伪一级反应速率常数达到9.91×10–3 min?1,分别是沸石类粉煤灰/TiO2光催化水泥样品和纯TiO2光催化水泥样品效能的3和10倍.光催化稳定性结果发现,在3次催化循环后,样品对气相苯的光催化去除率仍能达到96.3%(180 min).考虑到水泥基材料碳化是影响光催化剂使用耐久性的一个关键因素,我们还评估了沸石类粉煤灰/TiO2光催化水泥样品28 d加速碳化后的光催化性能.结果表明,经过加速碳化后,样品对气相苯光催化去除率只降低了11%,相比于同条件下纯TiO2水泥样品性能,其催化耐久性显著提高,表明沸石类粉煤灰载体可有效提升TiO2在水泥基体中的催化耐久性.这可能是由于其高孔隙特性可降低周围水泥水化产物的形成量,如高钙/硅比C-S-H凝胶及氢氧化钙结晶,进而降低了这些水化产物碳化所带来的影响.","authors":[{"authorName":"杨露","id":"1c0e7b16-f0c7-4795-8a50-7bb6dbe0781f","originalAuthorName":"杨露"},{"authorName":"高衣宁","id":"50d2f083-40bb-41c2-b4c3-45506cbef965","originalAuthorName":"高衣宁"},{"authorName":"王发洲","id":"efa595f8-d8ce-4b4a-a9e8-df71075024d4","originalAuthorName":"王发洲"},{"authorName":"刘鹏","id":"d7b0b333-d192-4b33-bca3-642708224e40","originalAuthorName":"刘鹏"},{"authorName":"胡曙光","id":"22218036-4506-456c-bc8c-3c15031595f1","originalAuthorName":"胡曙光"}],"doi":"10.1016/S1872-2067(16)62590-1","fpage":"357","id":"37c1ae71-0d49-45fc-aa27-f303e39dd5ad","issue":"2","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报

style=\"color:red\">集料</span>和粉煤灰漂珠,采用\"三步\"成型工艺制备沥青基复合材料,测试其路用性能,利用光照法研究其隔热功能,并借助扫描电镜(SEM)分析沥青胶浆与<span style=\"color:red\">集料</span>界面微观结构.结果表明,掺加多孔<span style=\"color:red\">集料</span>后复合材料路用性能满足相关要求;随粉煤灰漂珠和多孔玄武岩<span style=\"color:red\">集料</span>体积分数增加,抗压强度、动稳定度和浸水残留稳定度等路用性能先下降后升高;多孔玄武岩<span style=\"color:red\">集料</span>有利于抗滑性能提高.多孔<span
