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 N₂-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 °C and calcination temperature of 500 °C. Finally, these optimal conditions led to a CuZnAl material with excellent AsH₃ removal efficiencies for 10 h at 60 °C.

在这项研究中，通过水热法在不同的合成条件下制备了一系列CuZnAl类水滑石化合物（HTLC）前体。通过XRD，SEM-EDS，TGA和N ₂ -BET对煅烧后形成的HTLC及其各自的金属氧化物进行表征，以测定制备条件对其催化AsH ₃氧化和吸附性能的影响。确定的最佳参数是Cu：Zn为10：3，水热温度为105°C和煅烧温度为500°C。最后，这些最佳条件导致了CuZnAl材料在60°C下具有10个小时出色的AsH ₃去除效率。
