A series of Ag/MnO₂ nanorods with various loading amounts of Ag were fabricated and used for formaldehyde (HCHO) elimination. The obtained catalysts were characterized by means of N₂ adsorption–desorption, SEM, TEM, XRD, H₂-TPR, O₂-TPD and XPS. As the optimal loading amount of Ag was 0.1%, the Ag/MnO₂-r exhibited a superior catalytic performance for HCHO oxidation, on which the 100% conversion of HCHO was achieved at 80 °C. It has observed that the remarkable catalytic activity of 0.1% Ag/MnO₂-r was mainly due to the better low-temperature reducibility and more abundant surface active oxygen species resulting from the strong metal-support interaction between Ag and MnO₂.

制备了一系列具有不同载银量的Ag / MnO ₂纳米棒，并将其用于甲醛（HCHO）消除。利用N ₂吸附-脱附，SEM，TEM，XRD，H ₂ -TPR，O ₂ -TPD和XPS对所得催化剂进行了表征。由于Ag的最佳负载量为0.1％，对于Ag / MnO的₂ - [R展示的HCHO氧化优异的催化性能，在其上在80达到HCHO的转化率为100％℃。已观察到0.1％Ag / MnO ₂ - r的显着催化活性这主要是由于Ag和MnO ₂之间强烈的金属-载体相互作用导致更好的低温还原性和更丰富的表面活性氧种类。
