WebbAccording to the results, ORR intermediates (*OOH, *O, and *OH) become more stable due to the presence of a Co substrate. The single pyridinic (3NGpy) layer placed on Co (0001) is the most active site. The overpotential for Co/3NGpy is rather higher compared to pure Pt (111) catalyst (0.65 V).

The proton–proton chain is, like a decay chain, a series of reactions. The product of one reaction is the starting material of the next reaction. There are two main chains leading from hydrogen to helium in the Sun. One chain has five reactions, the other chain has six. Visa mer The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Visa mer The theory that proton–proton reactions are the basic principle by which the Sun and other stars burn was advocated by Arthur Eddington in the 1920s. At the time, the temperature of the Sun was considered to be too low to overcome the Coulomb barrier. … Visa mer • CNO cycle • Triple-alpha process Visa mer • Media related to Proton-proton chain reaction at Wikimedia Commons Visa mer The first step in all the branches is the fusion of two protons into a deuteron.
