采用ZnO模板法制备了具有介孔空心球结构、球壳厚度约为50 nm的聚合氮化碳纳米笼（PCNCs）。该方法是将ZnO纳米球和三聚氰胺通过简单煅烧，然后用盐酸和氨水去除ZnO模板和残余Zn 2+离子，制备出ZnO@ PCNCs核壳结构。采用多种物理化学方法，结合罗丹明B在水溶液中的光催化氧化反应和可见光下的光催化析氢反应，对所制备的PCNCs进行了表征。光催化性能评价结果表明，与传统煅烧法制备的本体PCN催化剂相比，PCNCs催化剂具有更高的光催化活性。表征结果表明，PCNCs催化剂的光催化性能的提高主要归因于其比表面积大、在2-50 nm范围内具有更多的介孔结构、较低的带隙能量、较高的可见光吸收率以及壳层中电子-空穴的有效分离。此外，具有空心球形结构的PCNC催化剂在两种光催化反应中都表现出良好的可重复使用性。
The polymeric carbon nitride nanocages (PCNCs) with mesoporous hollow spherical structures and a spherical shell thickness ofca50 nm have been successfully preparedviaan ZnO-template method, in which the ZnO@PCN core-shell structures were fabricated by simple calcination of ZnO nanospheres and deposited melamine, followed by sequential treatment with hydrochloric acid and aqueous ammonia for thorough removal of ZnO templates and residual Zn2+ions. The as-prepared pure PCNCs were characterized by various physico-chemical techniques combined with the photocatalytic oxidation reaction of rhodamine B in aqueous solution and the photocatalytic hydrogen evolution reaction under visible light irradiation. The photocatalytic evaluation results indicate that the PCNCs catalysts show higher activity for both photocatalytic reactions than the bulk PCN catalysts prepared by conventional calcination method. The characterization results have shown that the enhanced photocatalytic properties of PCNCs catalysts are mainly attributed to their larger specific surface area, more mesoporous in the range of 2–50 nm, lower band gap energy, higher visible light absorbance and more efficient electron-hole separation in the shell of hollow spherical nanocages than those of bulk PCN. Moreover, the PCNCs catalysts with hollow spherical structures exhibit an excellent reusability in both photocatalytic reactions.
