A Kirkendall strategy for simultaneously reduction of Cr (VI) and degradation of sulfamethoxazole via Cu-doped nZVI composites with nanocracks

Puntos clave

• Chromium (VI) reduction and sulfamethoxazole degradation occur effectively using Cu-doped nZVI composites.
• The method utilizes a novel Kirkendall strategy, enhancing efficiency through nanocracks in composites.
• Testing showed up to 90% chromium reduction and significant sulfamethoxazole degradation over a set timeframe.
• These findings suggest promising environmental applications, though further validation is required.
