Structural characterization indicated α-Fe2O3 nanoparticles were successfully loaded onto PCN. The α-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 α-Fe2O3/PCN heterojunction that addressed the recombination of photoinduced electrons and holes. The α-Fe2O3/PCN hybrids also showed high recyclability and chemical stability.
