摘要:
采用溶剂热法成功地合成了高比表面积的类石墨相g-C3N4. 详细地研究了合成时间对产物的形貌、晶相、阻抗、光电流响应及吸附性能的影响. 结果表明，随着合成时间的增加，产物的形貌从多孔块状变成多孔片状最后形成纤维网状，比表面积较体相g-C3N4明显增加，尤其是多孔片状g-C3N4的比表面积最大，达到了102.0 m2?g-1，且光电流响应值最高，阻抗值最小，对壬基酚和对硝基苯酚表现出优异的电催化活性，说明其在电化学传感方面将有良好的应用前景.
Abstract:
Graphite-like carbon nitride （g-C3N4） with high specific surface area was synthesized successfully by solvothermal method. The effects of reaction time on the morphology， crystal phase， electrochemical impedance spectroscopy， photocurrent responses and adsorption properties of the products were discussed in detail. The results show that the porous block， porous sheet and fiber net morphologies were obtained with the reaction time increasing. The specific surface areas of as-prepared g-C3N4 increase obviously comparing with that of the bulk g-C3N4. Particularly， the as-prepared porous sheet g-C3N4 exhibits excellent electrocatalytic activity for the nonylphenol and p-nitrophenol with the maximum photocurrent responses and the minimum resistance charge transfer value at the maximum specific surface area of 102.0 m2 /g， revealing that there is a good application prospects in electrochemical sensing.
