A bifunctional catalyst composed of ZnGaO with a spinel structure and molecular sieve SAPO-34 catalyses the direct conversion of CO to C-C olefins with a selectivity of 86% and a CO conversion of 13% at 370 °C. The oxygen vacancies on ZnGaO surfaces are responsible for CO activation, forming a methanol intermediate, which is then converted into C-C olefins in SAPO-34.
一种由具有尖晶石结构的ZnGaO和分子筛SAPO-34组成的双功能催化剂，在370℃下催化CO直接转化为碳-碳烯烃，选择性为86%，CO转化率为13%。ZnGaO表面的氧空位负责CO的活化，形成甲醇中间体，然后在SAPO-34中转化为碳-碳烯烃。
