摘　　要：类石墨氮化碳(g-C_3N_4)是一种新型的可见光光催化剂,但类石墨氮化碳g-C_3N_4本身有着的一些缺陷,直接造成其光催化效率低。为了消除这些缺陷的存在,提高其光催化效率。本文是将类石墨氮化碳(g-C_3N_4)进行加工处理得到厚度在50 nm左右的薄片,然后通过XRD、SEM和TEM等多种方法对该催化剂进行表征。并在可见光下对罗丹明B进行降解来判断其催化效率。Graphite-like carbon nitride （g-C3N4） is a novel visible-light photocatalysts, but g-C3N4 itself has some defects, which directly caused the low efficiency of photocatalytic. In order to eliminate these defects, which can be very good to improve its photocatalytic efficiency. This is a graphite - like carbon nitride （g-C3N4） process to get under 50 nm thick slices,then the catalyst was characterized by XRD , SEM and TEM..Under vile light to judge the efficiency of the catalytic degradation of Rhodamine B.
