摘要:

以乙酸锌、氢氧化钠和g-C3N4粉末为原料,并添加十二烷基苯磺酸钠粉末作为表面活性剂,采用室温固相研磨法制备了ZnO/g-C3N4光催化剂。并研究了复合材料的光催化性能。研究结果表明,经固相研磨后,会形成ZnO/g-C3N4复合材料,g-C3N4充分细化成薄片状。添加十二烷基苯磺酸钠粉末促进了g-C3N4发生相变。当g-C3N4含量较低时,产物的形貌呈现为纳米花,实际上是因为大量的氧化锌纳米片负载到g-C3N4片上。当g-C3N4含量较高时,产物为二维纳米片,由氧化锌纳米颗粒负载到g-C3N4片上。合成的ZnO/g-C3N4复合材料对亚甲基蓝表现出良好的可见光催化活性。

Abstract:

ZnO/g-C3N4 photocatalysts were prepared by solid-state grinding method at room temperature using Zn(CH3COO)2,NaOH and g-C3N4 powders as raw materials.Sodium dodecylbenzenesulfonate powder was added as a surfactant.The photocatalytic properties of the composites were studied.Results showed that ZnO/g-C3N4 composites formed after solid-state grinding and that g-C3N4 was refined into thin sheets.The addition of sodium dodecylbenzenesulfonate powder promoted the phase transformation of g-C3N4.When the content of g-C3N4 was low,the product assumed a nanoflower morphology,which was composed of a large number of ZnO nanosheets loaded on g-C3N4 flakes.When the content of g-C3N4 was higher,the produc presented many 2D g-C3N4 nanosheets loaded by ZnO nanocrystals.The synthesized ZnO/g-C3N4 composites exhibited good visible-light photocatalytic activity to methylene blue.

Key words: ZnO, g-C3N4, photocatalysis, solid-phase grinding
