    摘要:

    通過簡單的氨水水熱法制備得到了多孔g-C3N4光催化材料。利用 X 射線衍射（XRD）、紅外光譜（FT-IR）、掃描電子顯微鏡（SEM）、透射電子顯微鏡（TEM）研究了氨水對多孔g-C3N4結構的影響。并以亞甲基藍為目標分解物考察了樣品的可見光催化活性。研究結果表明：制備得到多孔g-C3N4具有由2D 納米片和相互連通的孔道組成的多孔納米結構。多孔g-C3N4的可見光催化活性得到了提升，原因在于相較于普通g-C3N4，多孔g-C3N4能夠提供更多的光催化反應活性位點，并且具有更高的光生載流子分離及遷移效率。

    Abstract:

    A simple and template-free synthesis method was developed to fabricate porous graphitic carbon nitride (g-C3N4) through a hydrothermal process in the presence of ammonium hydroxide. The effect of ammonium hydroxide on the structure of porous g-C3N4 was characterized in details by XRD, FT-IR, SEM and TEM. The photocatalytic activity of porous g-C3N4 was evaluated by the degradation of methylene blue (MB) under visible light irradiation. The results show that as-prepared porous g-C3N4 exhibits a porous nanostructure composed of 2D nanosheets and interconnected pores. The photocatalytic activity of porous g-C3N4 is enhanced, owing to the synergistic effect of more reaction sites and good separation efficiency of photo-generated carriers.
