In this work, we successfully developed a facile yet efficient microwave-assisted interfacial hydrothermal strategy to fabricate CdWO4 microspheres with a hydrophobic surface as an advanced photocatalyst for photocatalytic degradation of the dye Methyl Orange (MO) under ultraviolet (UV) light irradiation. The as-synthesized CdWO4 microspheres exhibited excellent photocatalytic degradation efficiency of 100% under UV illumination for 80 min, benefiting from its appropriate band gap, strong UV absorption, hydrophobic surface, and low recombination rate of photo-generated charge carriers. The striking stability and easy separation of the unique CdWO4 microspheres further promised its practical recycling usage. Also, insights into the formation and degradation mechanisms of CdWO4 microspheres were tentatively proposed.
