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...
The invention discloses a non-noble metal oxygen reduction catalyst for an alkaline ethanol fuel cell and a preparation method and application thereof. In the catalyst, metallic iron-containing chlorhematin is taken as an active ingredient, and active carbon powder is taken as a carrier. The ...
The excellent degradation capacity of RSPTW mainly comes from the hydroxyl radicals (center dot OH) and superoxygen radicals (center dot O-2(-)) produced by the rich hydroxyl on the surface of S + N-SnO2-(STS) due to the regulatory effect of STS and lower calcined temperature. The ...
The rationalization for the calculated energetics is related to the values of the ionization potential (IP) of the Rieske cluster and the electron affinity (EA) of the mononuclear iron complex: the latter is computed to be higher than the former, when dioxygen is bound to the metal. The...
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. ...
• Metal oxide + water —> metal hydroxide Na 2 O(s) + H 2 O(l) —> 2 NaOH(aq) Molecular O 2– (aq) + H 2 O(l) —> 2 OH – (aq) Net-ionic • Metal oxide + acid —> salt + water (Acid-base rxn!) Fe
We demonstrate the translation of a low-cost, non-precious metal cobalt phosphide (CoP) catalyst from 1 cm2 lab-scale experiments to a commercial-scale 86 cm2 polymer electrolyte membrane (PEM) electrolyser. A two-step bulk synthesis was adopted to produce CoP on a high-surface-area ca...
The oxygen reduction reaction (ORR) is a critical factor in fuel cells that has attracted significant research attention. Non-precious metal catalysts have improved the ORR activity considerably, but they still exhibit poorer ORR perform... Z Hong,C Su,KN Hui,... - 《Journal of the Electroche...
Binary metal oxides are attractive anode materials for lithium-ion batteries. Despite sustained effort into nanomaterials synthesis and understanding the initial discharge mechanism, the fundamental chemistry underpinning the charge and subsequent cycles
Non-noble Metal Electrocatalysts for the Hydrogen Evolution Reaction in Water Electrolysis Abstract Water electrolysis is a sustainable approach for hydrogen production by using electricity from clean energy sources. However, both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER...
