Optimizing surface active sites via burying single atom into subsurface lattice for boosted methanol electrooxidation.

ABSTRACT: The precise fabrication and regulation of the stable catalysts with desired performance still challengeable for single atom catalysts. Here, the Ru single atoms with different coordination environment in Ni₃FeN lattice are synthesized and studied as a typical case over alkaline methanol electrooxidation. The Ni₃FeN with buried Ru atoms in subsurface lattice (Ni₃FeN-Ru_buried) exhibits high selectivity and Faradaic efficiency of methanol to formate conversion. Meanwhile, operando spectroscopies reveal that the Ni₃FeN-Ru_buried exhibits an optimized adsorption of reactants along with an inhibited surface structural reconstruction. Additional theoretical simulations demonstrate that the Ni₃FeN-Ru_buried displ
