Pyroelectric catalytic performance of Sm3+-modified Pb(Mg1/3Nb2/3)O3–PbTiO3 for organic dyes: degradation efficiency, kinetics and pyroelectric catalytic mechanism

The degradation mechanism of Rh 6G by PMN-0.30PT: 1 mol% Sm 3+ with H 2 O 2 : heat energy is converted into electric energy under the temperature fluctuation, and is further converted into chemical energy for catalytic degradation.
