Article Synopsis
- The study addresses the trade-off between activity and selectivity in acetylene semi-hydrogenation by developing a new Au@PdCu core-shell nanocatalyst that enhances both properties.
- The nanocatalyst achieved 100% acetylene conversion and 92.4% ethylene selectivity at 122 °C, with performance 3.3 times better than a traditional PdCu alloy.
- Advanced techniques like pair distribution function (PDF) and reverse Monte Carlo simulation (RMC) were used to analyze the atomic structure, revealing that low coordination and tensile strain in palladium sites are key for improving catalytic performance.
