2.2.2. Temperature Programmed Reduction (TPR)

TPR measurements were carried out with a lab-made instrument at CATMAT laboratory, Ca' Foscari University of Venice. The analysis was performed under 5% H2/Ar (40 mL/min) from 25 ◦C to <sup>800</sup> ◦C with a heating rate of 10 ◦C/min. The H<sup>2</sup> consumption was analyzed by a Micrometrics TPD-TPR 2900 analyzer equipped with a TCD detector (Gow-Mac 24-550 TCD instrument CO, Bethlehem, PA, USA).
