Abstract Scope |
The advancement of affordable water-splitting technology is constrained by catalyst containing expensive noble metals such as platinum (Pt) and iridium (Ir). N-doped carbon supported single atom catalyst (NC-SAC) has been widely studied in the past few years due to the inexpensive carbon framework and the potential of utilizing cheap metals. Despite of the flourishing experimental discoveries, it is still not clear which local structure complex between C, N and single metal site will provide the desired catalytic activity. In this work, we have developed a complete computational dataset of NC-SAC by enumerating all practical transition metals combined with different local coordination environments. Multiple cheap metal-based NC-SACs are predicted with exceptional overpotential from density function theory calculations. Based on the computational results, we have revealed two pieces of dominating physics that governs the catalytic activity of metal sites for HER and OER. |
