Formation of highly active and porous structure electrocatalysts for watersplitting is a major challenge. Metal organic frameworks(MOFs) are one of the most promising precursors for developing advanced functional electrocatalysts with high porosity and structural merits. Herein, we report n-doped Co-CN nanoparticles are synthesized from core-shell zif-67/zif-8. Due to distinct reaction kinetics during MOF formation, partial distribution of different metals within a single MOF crystal can lead to sophisticate nanostructures by adding the two metals in sequence. Specifically, when Co2+ is added first, ZIF-67/ZIF-8 core–shell nanoparticles are achieved with tunable core thickness depending on the time intervals. This strategy might offer new insights to synthesize with controllable structures and enhanced catalytic performances. |
