Functionalized gold nanoparticles with a single layer of calix[4]arenes demonstrate remarkable electrocatalytic activity for the reduction of oxygen in water. Calix-based nanocatalysts display increased selectivity and stability compared to their citrate-stabilized counterparts. These nanohybrids operate according to a 4-electrons process with good electrocatalytic performance as well as great robustness.
