Promoting the oxygen reduction reaction with gold at step

Adding gold as the third element forming ternary Pt-based core–shell nanoparticles (NPs) is an efficient strategy for enhancing the durability of the cathode during the oxygen reduction reaction (ORR). Herein, using high-index (221) facets as a model catalyst, we discovered from density functional theory cal 2017 Catalysis Science & Technology HOT Articles

Gold corrosion

Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Yet this is precisely what Russian commercial precious metal trading company, International Reserve Payment System, discovered on thousands of (allegedly) 999 gold coins "St George" issued

Why silver and gold do not react with oxygen? Quora

Answer: This is due to the stability of compound. Silver and gold have a single outer electron. The lone electron is in an S-orbital. This orbital is thus half filled (since s-orbitals can contain 2 electrons) and all the other inner orbitals in silver and gold are filled, and hence stable. Afte...
