摘要：
alpha-Fe2O3/porous g-C3N4 (e-Fe2O3/PCN) photocatalysts were fabricated via a facile and green method. Structural characterization indicated alpha-Fe2O3 nanoparticles were successfully loaded onto PCN. The alpha-Fe2O3/PCN nanocomposites were proven durable with significantly enhanced photocatalytic activity for Rhodamine B photodegradation than the single components under visible light irradiation. The improved photoactivity was mainly attributed to the broadened visible light absorption, enriched active sites, and formation of alpha-Fe2O3/PCN heterojunction that addressed the recombination of photoinduced electrons and holes. The alpha-Fe2O3/PCN hybrids also showed high recyclability and chemical stability.
