Cr2O3 nanoparticles anchored on ZnO nanorods as active heterostructure catalysts for phenol degradation

With the rapid civilization and industrialization, water pollution is becoming more and more intricate. Heterogeneous photocatalysis using metal oxide loaded ZnO nanorods is a well-known environmental technology to degrade toxic organic pollutants. In this study, Cr2O3 particles anchored on the Zn...
