文摘
- •
A novel heterogeneous catalyst (Z-nZVFe-Cu) was prepared using ion exchange method.
- •
The combined effect of iron and copper enhanced the catalytic activity of Z-nZVFe-Cu.
- •
Z-nZVFe-Cu demonstrated an excellent performance for TCE degradation.
- •
The hydroxyl radicals (OH
) played the major role in TCE degradation.- •
The low leaching of Fe and Cu suggested its prolonged stability.
