This high electrochemical performance can demonstrate high speed charge transfer, enhance conductivity and increase the generation of oxygen vacancies due to the doping of Al and Ce elements. The above-mentioned results shown in Table 2. In addition, the OER and HER performance of so-synthesized...
The smallest value of Heff is for Sariçiçek howardite which may be related to the largest number of Fe vacancies in FeS in comparison with ordinary chondrites. This fact may be a result of the differentiation of Sariçiçek howardite in the parent body (asteroid (4) Vesta) ...
Due to structural vacancies within the octahedral sheets and/or because of the substitution of Mn3+ for Mn4+ within the [MnO6] octahedral sheets, all three manganese phases have a negative layer charge deficit, which can be compensated by the incorporation of metals into the vacancies or by ...
