Bimetallic calcium-lanthanide oxides (Ln = La, Ce, Sm, Gd, Yb) were tested for the first time as catalysts in the oxidative coupling of methane (OCM) using nitrous oxide as oxidant. The reaction main products were C2 hydrocarbons. The best results were those obtained with bimetallic calcium-lanthanum and calcium-samarium oxides that achieve hydrocarbons yields comparable to the best reported in the literature using O₂ as oxidant. The catalytic performance is clearly dependent of an interaction between calcium and f block element due to calcium ions incorporation on the lanthanide oxide matrix (except for CeO₂) that renders oxygen less labile and increases hydrocarbons production. The other main factor that correlate with the variation of the activity and selectivity along the lanthanide series is the catalysts basic properties that increases hydrocarbon production. The catalysts present also an unusual and long stability in the gaseous stream.

首次测试了使用氧化亚氮作为氧化剂的甲烷（OCM）氧化偶联中的双金属钙-镧系元素氧化物（Ln = La，Ce，Sm，Gd，Yb）。反应的主要产物是C 2烃。最好的结果是使用双金属钙镧和钙-氧化物获得的结果，与使用O ₂作为氧化剂的烃类产量相比，可获得最佳的碳氢化合物收率。催化性能显然取决于钙和f嵌段元素之间的相互作用，这是由于钙离子掺入镧系元素氧化物基质（CeO ₂除外）引起的。），这样可以减少氧气的不稳定并增加碳氢化合物的产量。与沿着镧系系列的活性和选择性的变化相关的另一个主要因素是增加烃产量的催化剂基本性质。催化剂在气流中也表现出异常和长期的稳定性。
