The rates of attrition of batches of these particles whilst they were being fluidised and subjected to successive cycles of reduction and oxidation were determined by measuring the rate of production of fine particles elutriated from the bed, as well as progressive changes in the distribution of particle sizes retained in the bed.
In this experiment, after completion of every reduction cycle, the catalyst was collected by centrifugation, dried and used for the next cycle of reduction.
Also, the FTIR spectra of the catalyst before and after five cycles and ten cycles of catalytic reduction were shown in ESI.
As shown in Additional file 1: Figure S7, after five and ten cycles of catalytic reduction, the main peaks of the samples were almost the same with the as-prepared sample and this illustrates that the catalysts are very stable.
