Description

A kind of cage structure material g-C3N4Preparation method and applications
Technical field
The present invention relates to a kind of cage structure material g-C3N4Preparation method and applications.
Background technology
In recent years, a kind of nonmetallic organic polymer semiconductor functional material --- class graphite phase carbon nitride（g-C3N4）By In it with relatively low energy gap（Eg=2.70 eV）, higher chemical stability, it is easily modified, prepare it is simple, to visible ray Response is good and has the advantages that higher photocatalysis performance, is widely paid close attention to.But g-C prepared by current usual method3N4 Block random pattern is presented, specific surface area and pore volume are relatively low, strongly limit its application in most of fields.
At present, people's generally use hard template preparation method, using melamine, dicyandiamide or urea as preparation g-C3N4's Presoma, by introducing template in heat polymerization process, to control g-C3N4Microscopic appearance, so as to synthesize with Gao Bibiao Face and the mesoporous g-C of pore volume3N4.Commonly used more hard mould agent includes silica, and SBA-15 and KIT-6 etc., pass through From different C3N4Presoma combines, and prepares the g-C with loose structure3N4, g-C is greatly improved3N4Specific surface area, increase Electronics captures site and is conducive to the separation of photo-generated carrier, so as to improve photocatalysis performance and widen it in other catalysis The application in oxidation field.Such as Wang Xing morning seminars are using having shell structurre SiO2Prepared for hard mould agent with hollow The bionical g-C of structure3N4Nanoparticle, and substantially increase the efficiency of its Photocatalyzed Hydrogen Production（Nature Communications, 2012,3 (4):1139.Markus Antonietti seminars are utilized with regular pore canal structure SBA-15 nanometer rods are template, are evaporated after uniformly being mixed with cyanamide presoma, the thermal polymerization formation g-C at 550 DEG C3N4@ SBA-15 composite nano materials, finally using NH4HF2Template SBA-15 is removed to prepare mesoporous g-C3N4Nanometer rods.But current institute The template of use is to g-C3N4Affinity it is poor, be not easy to form meso-hole structure.
ZnO is as amphoteric oxide, usually as a kind of Photocatalysis Function Material of excellent performance, due to its energy gap It is larger, apply the photocatalytic degradation organic matter under ultraviolet excitation more.At present, most researcher is relatively narrow with energy gap by it Semi-conducting material is compounded to form compound dissimilar materials, to widen its application in photocatalytic degradation field significantly.For example, publication number A kind of ZnO/ g-C for preparing core shell structure are disclosed for the patent of CN106430286A3N4The method of composite material, using urea It is soluble in water at room temperature for presoma, then add Zinc oxide nanoparticle and uniformly mix, then 450 DEG C of 2 h of roasting, obtain The ZnO/ g-C of faint yellow core shell structure3N4Composite material.But applications of the ZnO in terms of template was not reported so far.
