Synthesis of ultrafine Co/CoO nanoparticle-embedded N-doped carbon framework magnetic material and application for 4-nitrophenol catalytic reduction

An ultrafine Co/CoO nanoparticle-embedded N-doped porous carbon framework magnetic material was successfully synthesized based on a designed Co-MOF. Co/CoO@NC has good catalytic activity and recyclability for the 4-NP reduction reaction.

Construction of nitrogen-doped porous carbon nanosheets decorated with Fe–N4 and iron oxides by a biomass coordination strategy for efficient oxygen reduction reaction

A highly efficient Fe₂O₃@C/FeNC electrocatalyst with Fe–N₄ and iron oxides decorated on nitrogen doped carbon nanosheets has been synthesized by the one-step pyrolysis of Fe-coordinated egg white without acid leaching assistance.
