| 英文摘要 | Low-concentration nitrogen oxide (NOx) is a major atmospheric pollutant that can ideally be removed by photocatalysis. At present, photocatalytic techniques for NO removal still suffer from certain problems, such as low efficiency and secondary pollution. In this study, the surface of g-C(3)N(4)was modified with illite particles, which not only enhanced the photocatalytic NO removal activity of g-C3N4, but also reduced the generation of secondary pollutants (NO2). This is mainly attributed to the formation of heterojunctions between illite and g-C3N4, which promoted charge transfer. Moreover, interface defects and an electric field were formed when the surface of g-C(3)N(4)was modified with illite. These interface defects and the electric field could further accelerate interfacial charge transfer. Additionally, modification with illite caused the surface of g-C(3)N(4)to peel and roll up. These curls increased O(2)adsorption on the composite to produce more reactive oxygen species. This study provides new insight into the effective utilization of natural minerals in pollution control. |
