The high-dispersed Ag modified g-C3N4 (Ag/g-C3N4) was successfully synthesized in situ deposited on the surface of g-C3N4 during calcined melamine.

The as-prepared Ppy@Ag/g-C3N4 could remove of various organic pollutants in water.

The enhanced photocatalytic activity of Ppy@Ag/g-C3N4 comes from π conjugated electronic structures of Ppy and Ag species as the electron transfer mediator between Ppy and g-C3N4.

The Ppy@Ag/g-C3N4 sample also showed a relatively good recycling stability.
