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-Ruburied) ... https://atlanticknifers.shop/product-category/eyewear/
