The search for efficient Haber-Bosch catalysts toward ammonia production under mild conditions is never-ending, which greatly limited by the Brønsted-Evans-Polanyi (BEP) relationship. Great efforts have been put into optimizing BEP relations and achieving Sabatier optimum, requires a balance between dissociation hydrogenation of nitrogen. However, challenges in this field inspire us to believe that completely breaking linear indeed final target although out sight such holy grail reaction....
Ruthenium (Ru) is considered as a highly promising catalyst for hydrogen evolution reaction (HER) because of its similar d-band center to platinum and more affordable price. However, the catalytic activities...
