摘要：
In this study, a series of CuZnAl hydrotalcite-like compound (HTLC) precursors were prepared by a hydrothermal method under varying synthesis conditions. The HTLCs and their respective metal oxides formed after calcination were characterized by XRD, SEM-EDS, TGA and N-2-BET with the aim to determine the effect of the preparation conditions on their catalytic performance towards AsH3 oxidation and adsorption. The optimal parameters determined were Cu:Zn of 10:3, hydrothermal temperature of 105 degrees C and calcination temperature of 500 degrees C. Finally, these optimal conditions led to a CuZnAl material with excellent AsH3 removal efficiencies for 10 h at 60 degrees C.
