Enhancing the photocatalytic activity and photostability of zinc oxide nanorod arrays via graphitic carbon mediation

Graphitic-carbon-mediated ZnO nanorod arrays (NRAs) are fabricated by calcining pre-synthesized ZnO NRAs with different amounts of glucose as a carbon source, via a hydrothermal method. The resulting nanohybrids exhibit enhanced photocatalytic activity and photostability for CO2 reduction under visible light irradiation.
