Cobalt-magnesium-aluminum oxides derived from layered double hydroxides were used as catalysts for the conversion of methanol to formaldehyde in the presence of nitrous oxide. The catalysts were characterized by XRD, FTIR, UV–vis DRS, TPR-H₂, NH₃- and CO₂-TPD and N₂ adsorption. 100% methanol conversion and 91% selectivity to formaldehyde were simultaneously obtained with 100% N₂O conversion at 440 °C over a Co,Mg,Al-mixed oxide catalyst. Higher hydrogen yields and lower CO and CO₂ yields were obtained than when air was used as oxidizing agent, under the same conditions. These findings suggest that the reaction occurs on a combination of redox and basic catalytic sites.

衍生自层状双氢氧化物的钴-镁-铝氧化物用作在一氧化二氮存在下甲醇转化为甲醛的催化剂。通过XRD，FTIR，UV-vis DRS，TPR-H ₂，NH _3-和CO ₂ -TPD和N ₂吸附对催化剂进行了表征。在440°C的Co，Mg，Al混合氧化物催化剂上，同时以100％N ₂ O的转化率同时获得100％的甲醇转化率和91％的甲醛选择性。在相同条件下，与使用空气作为氧化剂相比，可以获得更高的氢产率和更低的CO和CO ₂产率。这些发现表明该反应在氧化还原和碱性催化位点的组合上发生。
