Abstract The utilization of nanoscale catalysts represents a valuable and promising strategy for augmenting catalytic performance while mitigating the reliance on expensive noble metals. Nevertheless, significant knowledge gap persists regarding intricate interplay between catalyst size, physical properties, behavior in context oxygen reduction reaction. In this study, synthesis precisely controlled palladium is presented, spanning wide range from individual atoms to metal clusters nanoparticles, followed by comprehensive evaluation their acidic conditions. results show increase H 2 O selectivity up 96% with decreasing size strategic approaches are identified eliminate unselective sites, facilitating attainment active selective catalysts. enhanced highlights potential single atom sites can be adapted improve various processes.
