Engineering local nitrogen coordination environments of Palladium subnanometric clusters in metal-organic frameworks for efficient hydrogenation.
Subnanometric clusters (SCs) bridge the gap between single-atom catalysts and nanoparticles by combining high atomic utilization with cooperative multi-atom effects. However, stabilizing low-coordinated SCs while maintaining accessible active sites remains challenging. Here, we introduce pyrazole-3,5-dicarboxylic acid...
