Graphitic carbon nitride (g-C3N4) is a promising material for photocatalytic applications. However, it suffers from poor visible-light absorption and high recombination rate of photogenerated electron–hole pairs. Here, Co/La@g-C3N4 with enhanced activity was prepared by co-doping Co La into g-C3N4 via facile one-pot synthesis. displayed better performance, achieving 94% tetracycline (TC) removal within 40 min, as compared (BCN, 65%). It also demonstrated performance in degrading other pollutants, which ~2–4-fold greater relative to BCN. The improved associated charge separation, reduced transfer resistance, built-in electric field arising the p-n-p heterojunction, synergistic effect ternary components separation carriers. Superoxide radicals are suggested be most notable reactive species responsible reaction. Environmental factors, including pollutant concentration, catalyst dosage, solution pH, inorganic salts, water matrices, mixture dyes, were considered reactions. showed good reusability five cycles degradation TC. formed heterojunction boosted highly efficient TC various matrices.
