Engineering catalyst supports to stabilize PdOx two-dimensional rafts for water-tolerant methane oxidation

The treatment of emissions from natural gas engines is an important area research since methane a potent greenhouse gas. benchmark catalysts, based on Pd, still face challenges such as water poisoning and long-term stability. Here we report approach for catalyst synthesis that relies the trapping metal single atoms support surface, in thermally stable form, to modify nature further deposited metal/metal oxide. By anchoring Pt ions can tailor morphology phase. In particular, two-dimensional (2D) rafts PdOx are formed, resulting higher reaction rates improved tolerance during oxidation. results show modifying by could provide addition toolkit designers controlling nucleation growth oxide clusters heterogeneous catalysts. Despite its importance context treatment, oxidation remains challenging. Now, authors introduce stabilize ceria superior this transformation.
