摘要：

The abuse of pesticides and antibiotics and their harm to the environment are the disadvantages of modern agriculture and breeding industry. g-C3N4 has shown great potential in photocatalytic water pollution purification under visible light irradiation, however, the conventional g-C3N4 suffers from the disadvantage of limited optical absorption and serious charge recombination, resulting in inefficient light energy conversion and pollutant degradation. This study provides a strategy of combining defect engineering with a built-in electric field...
