| description | A porous ball-flower-like Co<sub>3</sub>O<sub>4</sub>/Fe<sub>2</sub>O<sub>3</sub> heterostructural photocatalyst was synthesized via a facile metal–organic-framework-templated method, and showed an excellent degradation performance in the model molecule rhodamine B under visible light irradiation. This enhanced photocatalytic activity can be attributed to abundant photo-generated holes and hydroxyl radicals, and the combined effects involving a porous structure, strong visible-light absorption, and improved interfacial charge separation. It is notable that the ecotoxicity of the treated reaction solution was also evaluated, confirming that an as-synthesized Co<sub>3</sub>O<sub>4</sub>/Fe<sub>2</sub>O<sub>3</sub> catalyst could afford the sunlight-driven long-term recyclable degradation of dye-contaminated wastewater into non-toxic and colorless wastewater. |
