AB The ultimate target in heterogeneous catalysis is the achievement of robust, resilient and highly efficient materials capable of resisting industrial reaction conditions. Pursuing that goal in liquid-phase hydroformylationposes a unique challenge due to carbon monoxide-induced metal carbonyl species formation, which is directlyrelated to the formation of active homogeneous catalysts by metal leaching. Herein, supported heteroatomincorporated (P and N) Co nanoparticles were developed to enhance the resistance compared with bare Conanoparticles. The samples underwent characterization using operando XPS, XAS and HR electron microscopy.Overall, P- and N-doped catalysts increased reusability and suppressed leaching. Among the studied catalysts, theone with N as a dopant, CoNx@NC, presents excellent catalytic results for a Co-based catalyst, with a 94%conversion and a selectivity to aldehydes of 80% in only 7.5 h. Even under milder conditions, this catalystoutperformed existing benchmarks in Turnover Numbers (TON) and productivity. In addition, computationalsimulations provided atomistic insights, shedding light on the remarkable resistance of small Co clusters interacting with N-doped carbon patches.
