摘要

研究了g-C3N4在LiCl和KCl熔体中热处理得到的块状石墨型氮化碳(g-C3N4)、结晶型氮化碳(CGCN)和乳酸溶液处理后的CGCN的光致发光性能。已经确定，发光性能在很大程度上取决于它们的形态和杂质以及结构缺陷的存在。结果表明，在乙醇氧化反应中，样品的发光强度与光催化活性之间存在着拮抗关系。

Luminescent and Photocatalytic Properties of Bulk and Crystalline Graphitic Carbon Nitride

The photoluminescence of bulk graphitic carbon nitride (g-C₃N₄), crystalline carbon nitride (CGCN) obtained by thermal treatment of g-C₃N₄ in LiCl and KCl melts, and CGCN treated with a lactic acid solution (AT-CGCN) has been studied. It has been established that the luminescent properties largely depend on their morphology and the presence of impurities as well as structural defects. It is shown that there is an antibatic dependence between the luminescence intensity and the photocatalytic activity of the samples in the ethanol oxidation reaction.
