Abstract

The effects of annealing temperature on the catalytic degradation capacity of Fe₇₅P₁₅C₁₀ amorphous ribbons in the photo-enhanced Fenton-like reactions are studied using reactive red 195 (RR195) solution. The order of catalytic degradation capacity of the ribbons is AN722 ≥ AN662 ≥ AS ≥ AN542 ≥ AN602, the AN722 ribbon has the highest k (0.349 min − 1), the lowest t_{η ≥ 95 %} (10 min) values, and compared with AS ribbon has good reusability (9 times). Firstly, isothermal annealing is a process of metastable structural relaxation, in which the energy stored in AS ribbon is gradually released, and the high thermodynamic enthalpy and residual stress decrease, which jointly lead to the decline of the catalytic degradation capacity of the ribbons. Secondly, the precipitation of Fe₃P nanocrystal/nanophase and amorphous matrix, identified by TEM, induces the formation of galvanic cells effect increase the electron donation rate in the reaction, thus restoring/improving its catalytic degradation capacity.
