| 中文摘要: |
| 以二氰二胺为前驱体,不同晶化温度的SBA-15作为硬模板,通过纳米浇铸法,合成了一系列比表面和孔体积可调的介孔石墨相氮化碳(CND-SBA15)。通过N2吸–脱附、TEM、小角XRD、XPS、FT-IR、CO2-TPD等一系列表征手段分别研究了材料的织构、微观形貌、孔结构的有序性、化学组成和碱性质等性质。在以苯甲醛和丙二腈为底物的Knoevenagel缩合反应中,CND-SBA15材料表现出了很好的催化活性和稳定性。 |
| 英文摘要: |
| A series of mesoporous graphitic carbon nitride materials (CND-SBA15) with tunable surface areas and pore volumes have been prepared using dicyandiamide as a precursor. SBA-15 samples as templates synthesized under different hydrothermal temperatures. Several techniques including N2 adsorption–desorption, TEM, small angle XRD, XPS, FT-IR, and CO2-TPD were employed to characterize the textual properties, microscopic morphology, porous orderness, chemical compositions, and basic properties, respectively. In Knoevenagel condensation reaction between benzyl aldehyde and malononitrile, CND-SBA15 materials demonstrated high catalytic activity and stability. |
