Comparison of various organic compounds destruction on rare earths doped Ti/Sb-SnO2 electrodes

► Different REs doping has distinct effect on the Ti/Sb-SnO2 electrode performance. ► Gd or Eu improves the performance of Ti/Sb-SnO2 on aromatic ring cleavage. ► Catechol is more refractory to be degraded than benzoquinone and hydroquinone. ► The molecular structure of organic compound influences its degradation rate.
