Catalytic oxidation of volatile organic compounds such as toluene over a range of silver-based catalysts has been carried out to assess their performance. The properties of the catalysts were determined by the Brunauer-Emmett-Teller method, X-ray diffraction, and temperature-programmed reduction. The experimental results revealed that the catalytic activity of an Ag/gamma-Al2O3 catalyst is closely related to the silver loading, and the optimum loading for the complete oxidation of toluene was found to be 11 wt%. The addition of copper to the 11 wt% Ag/gamma-Al2O3 catalyst greatly enhanced its catalytic activity, but the addition of cerium or lanthanum inhibited catalytic activity.
已经对一系列银基催化剂上的挥发性有机化合物（如甲苯）的催化氧化进行了研究，以评估它们的性能。通过 Brunauer-Emmett-Teller 方法、X 射线衍射和程序升温还原来确定催化剂的性质。实验结果表明，Ag/gamma-Al2O3 催化剂的催化活性与银的负载量密切相关，并且发现甲苯完全氧化的最佳负载量为 11wt%。在 11wt%Ag/gamma-Al2O3 催化剂中添加铜极大地提高了其催化活性，但添加铈或镧则抑制了催化活性。
