This work also provides a general design principle for further exploration of an even broader composition space of MBenes and other 2D NRR electrocatalysts.

Generally it is believed that core quantum dots (QDs) are good reducing agents and are used for that purpose in solar hydrogen generation and various organic transformations. However, core QDs are very unstable. Core/shell dots are more robust, but the shell minimizes redox activity. Researchers now demonstrate that this isn't perfectly true. In fact, they found that certain core/shell materials are a better reducing agent than the core alone. Most importantly, core/shell QDs are substantially more robust than the core alone.
