随着现代工业的飞速发展,如何实现氮氧化物的有效脱除成为目前亟待解决的重要难题.本研究提出了一种在石墨相氮化碳(g-C_(3)n.(4))表面原位生长纳米氧化锌点阵构建柱撑结构复合材料策略,以实现在可见光下光氧化去除n..通过离子吸附反应,成功制备了不同氧化锌颗粒负载量的Zn. n./g-C_(3)n.(4)柱撑结构复合光氧化剂,并对其结构和电子特性进行了研究.结果表明,氧化锌纳米颗粒(Zn. n.)的引入改善了g-C_(3)n.(4)的团聚,提高了比表面积,暴露出更多活性位点.异质结构的构建改善了复合材料能带结构,促进了光生载流子的迁移及分离,光氧化性能显著提升.在可见光照射下质量分数为2.5%的Zn. n./g-C_(3)n.(4)样品展现出了优异的光氧化性能,对n.体积分数为3×10^(-5)%以下的混合空气光氧化去除表现出优良的高效稳定性.本研究为高性能光氧化剂的设计与构建提供了有效策略,并为消除工业n.污染物提供了技术参考.

The econ.m. of Sw.zilan. is depen.ed on.agriculture. In.2009, it w.s reported that agriculture, forestry, an. m.n.facturin. con.ributed 42% of Sw.zilan.’s Gross Dom.stic Product (GDP). Besides econ.m.c im.ortan.e, an.m.l agriculture is im.ortan. for food production.an. life susten.n.e. It is also view.d as a sym.ol of w.alth an. high social status particularly for the rural folks. Despite the m.rits of agricultural activities, agricultural production. particularly an.m.l production. has been.in.rim.n.ted for an.accelerated em.ssion.of green.ouse gases. These gases are respon.ible for global w.rm.n. an. clim.te chan.e. The aim.of this study w.s to determ.n. the con.ribution.of an.m.l agriculture to green.ouse gases production.an. to elicit adaptation.strategies to clim.te chan.e an. the role of m.dern.techn.logies as m.tigatin. m.asures.
