摘要:
以盐酸胍为前驱体,纳米氧化硅小球为模板剂,通过调节纳米氧化硅小球与盐酸胍的质量比,合成了一系列比表面(146~194 m2·g-1)和孔体积(0.57~0.75 cm3·g-1)可调的介孔石墨相氮化碳(mp-C3N4)。通过N2吸-脱附、透射电镜、X射线衍射、傅里叶红外光谱、X射线光电子能谱等手段对材料的孔结构、微观形貌和化学组成等理化性质进行表征。在CO2环加成反应合成碳酸丙烯酯的催化反应中,mp-C3N4材料表现出良好的催化性能。在反应温度120 ℃条件下,碳酸丙烯酯的选择性和收率分别高达98%和76%。根据理化表征提出了一种可能的催化机理。
Abstract:
A series of mesoporous g-C3N4 materials(mp-C3N4)with tunable surface areas(146-194 m2·g-1)and pore volumes(0.57-0.75 cm3·g-1)have been synthesized using guanidinium chloride as a precursor, and colloid silica nanoparticles as hard templates through a nanocasting method. The physicochemical properties of mp-C3N4 materials(including porosity, micrograph, and chemical compositions)were characterized by N2 adsorption-desorption, XRD, TEM, FT-IR, and XPS spectroscopy. In the cycloaddition reactions of CO2 with propylene oxide to propylene carbonate(PC), the mp-C3N4 materials showed high catalytic performances. The maximum selectivity and yield of PC were up to 98% and 76%, respectively at 120 ℃. On the basis of the characterization results, a possible catalytic mechanism has been proposed.
