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.
