The invention also discloses a non-metal oxygen reduction electrode. The catalyst obtained by the invention is a high polymer material poly(3, 4-ethylenedioxythiophene), which has oxygen reduction catalytic activity, does not have the problems of displacement, aggregation, poisoning and the like of...
Metal have 1 to 3 electrons in the outer shell whereas non-metal have 4 to 8 electrons. Metal oxide is formed when a metal reacts with oxygen and forms electrovalent or ionic bonds, e whereas non-metals form non-metal oxides when they react with oxygen and mostly form covalent bonds. ...

• Oxygen is easily reduced, very good oxidizing agent. (Negative 1st electron affinity.) • Oxygen forms two less common ions: Peroxide O 2 2– as in H 2 O 2 (aq) Superoxide O 2 – as in KO 2 (s) • Sulfur is similar to oxygen except much less reactive. • Sulfur comes...
Some metal nitrides (Me = W, Mo) and oxynitrides (Me = Ta, Zr, Nb) are promising regarding the observed onset potentials (up to 0.8 V vs. NHE) and could be of interest for further investigation. In this respect, however, the readers are referred to the original contributions (W 2 ...

single/dual/multiple doped non-metal nanocarbon ORR electrocatalysts have been investigated in succession. Owing to the incorporated heteroatoms with different electronegativity, the local charge and spin density of the carbon matrix have been significantly altered, which can facilitate the oxygen adsorption...
