[EN] Rh2P nanoparticles (NPs) have been identified as suitable mimics of [Rh-I(Ph3P)(3)](+), the benchmark of homogeneous catalysts in liquid-phase hydroformylation. For this reason, a fitted synthetic strategy is required ...
[EN] Modulating the structures of subnanometric metal clusters at the atomic level is a great synthetic and characterization challenge in catalysis. Here, we show how the catalytic properties of subnanometric platinum ...
