magnetic particles are prepared by impregnation-thermal decomposition method. To obtain the optimum surface element contents
crystal structure and particle magnetism
six coating times of the particles are determined. Comparing the cyclic voltammetry properties
hydroxyl radical yields and mass transfer coefficients
it is found that the 2.5D elec
trode system is superior to the 2D electrode system in performance
and the optimum particle dosage is determined as 5 g. Finally
acid red G is used as the target to compare the electrocatalytic performance of the two electrode systems. The results show that the decolori-ation rate
