Metal-organic frameworks derived reverse-encapsulation Co-NC@Mo2C complex for efficient overall water splitting
Abstract
Abstract Developing low-cost, highly active, and stable bifunctional electrocatalysts is a challenging issue in electrochemical water electrolysis. Herein, we develop a simple metal organic frameworks (MOFs) based approach to prepare bifunctional Co-NC@ Mo2C complex catalysts. Differently from traditional carbon encapsulated functional nanomaterials, herein the carbon-based framework derived carbonitride and Co nanoparticles (Co-NC) are encapsulated with Mo2C. Benefiting from the unique reverse-encapsulation structure and synergetic effects of Mo2C and Co-NC, the Co-NC@Mo2C catalyst shows superior hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) performance. In alkaline media, it affords the current density of 10 mA cm−2 at low overpotentials of 99 mV and 347 mV for HER and OER, respectively. Interestingly, due to a reversed encapsulation structure where Co nanoparticles are protected by Mo2C, it leads to an outstanding HER catalytic activity (a low overpotential of 143 mV) and stability in acidic solutions. Remarkably, when employed as both the cathode and anode for overall water splitting, a low cell voltage of 1.685 V is required to reach the current density of 10 mA cm−2 in alkaline media with excellent stability, making the Co-NC@Mo2C an efficient non noble metal bifunctional electrocatalyst toward water splitting.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
