Enhancing Bifunctional Electrocatalytic Activities of Oxygen Electrodes via Incorporating Highly Conductive Sm and Nd Double-Doped Ceria for Reversible Solid Oxide Cells.

Solid oxide cells (SOCs) are mutually convertible energy devices capable of generating electricity from chemical fuels including hydrogen in the fuel cell mode and producing green hydrogen using electricity from renewable but intermittent solar and wind resources in the electrolysis cell mode. An effective approach to enhance the performance of SOCs at reduced temperatures is by developing highly active oxygen electrodes for both oxygen reduction and oxygen evolution reactions. Herein, highly conductive Sm and Nd double-doped ceria (SmNdCeO, SNDC) is utilized as an active component for reversible SOC applications.

Crystal structure of strontium perchlorate anhydrate, Sr(ClO), from laboratory powder X-ray diffraction data.

The crystal structure of strontium perchlorate anhydrate, Sr(ClO), was determined and refined from laboratory powder X-ray diffraction data. The material was obtained by dehydration of Sr(ClO)·3HO at 523 K for two weeks. It crystallizes in the ortho-rhom-bic space group and is isotypic with Ca(AlD) and Ca(ClO).
