N2 - In order to investigate the feasibility of applying Zn rods (ZR) from spent primary batteries (SPBs) as a catalyst support for the complete oxidation of volatile organic compounds (VOCs), the prepared Pt catalyst based on Zn rod (Pt/SZR) was tested for the oxidation of benzene, toluene, and o-xylene. The catalyst’s basic properties of Pt/SZR catalysts were characterized by BET analysis, XRD, H2-TPR, SEM/EDX, TEM and XPS. The main ingredient of ZR was zinc oxide. As expected, for the Pt/SZR catalyst, increasing the amount of Pt added to the SZR from 0.1 wt% to 1.0 wt% increased the conversions of benzene, toluene, and o-xylene. The reaction temperature for complete oxidation of benzene, toluene, and o-xylene over the 1.0 wt% Pt/SZR catalyst was less than 310 °C at GHSV of 50,000 h−1. TEM, XPS, and H2-TPR analysis indicated that the increase in catalytic performance due to Pt added was attributed to the active component (Pt species) and also to the readily movable lattice oxygen. This results indicate that ZR of SPBs is promising as a catalyst support for the oxidation of VOCs.
