Enhancing performance of molybdenum doped strontium

Enhancing performance of molybdenum doped strontium

Mar 11, 2021 Molybdenum doped strontium ferrite, Sr 2 Fe 1.5 O 0.5 O 6 (SFM), is a promising perovskite-type hydrogen electrode material in solid oxide cells (SOCs), but usually suffers from insufficient electro-catalytic activity. Herein, Ni nanoparticles with high electro-catalytic properties have been infiltrated into SFM scaffold to form Ni-SFM electrode with high electro-catalytic activity for power ...

Feb 15, 2020 A Pr-doping strategy was used to improve traditional strontium-doped lanthanum ferrite oxides for proton-conducting solid oxide fuel cells (SOFCs). Three different samples, La 0.5 Sr 0.5 FeO 3- δ , La 0.25 Pr 0.25 Sr 0.5 FeO 3- δ , and Pr 0.5 Sr 0.5 FeO 3- δ ,were successfully prepared.

Effect of Composition on the Redox Performance of

Jun 25, 2020 Chemical looping dry reforming of methane is an attractive approach to use carbon dioxide and methane, the two most abundant greenhouse gases. For this scheme, the redox material (or oxygen carrier) plays a key role. It is of great significance to improve the redox performance of strontium ferrite (SrFeO3−δ, SFO), a low-cost and easily tunable perovskite-typed oxygen carrier. …

Electrochemical Performance of Barium Strontium Cobalt

Electrochemical Performance of Barium Strontium Cobalt

A low operating temperature is one of the concerns in commercialising solid oxide fuel cells (SOFCs) as a portable power source. The aim of this research is to develop a new cathode material, barium strontium cobalt ferrite–samarium doped ceria (BSCF-SDC) added with argentum (Ag) for low-temperature SOFCs (LT-SOFCs). The composite powder was prepared through high-energy ball milling at 550 ...

Permanent Magnets Ferrite Hitachi Metals

Ferrite magnets are more commonly referred to as ceramic magnets. They are mostly composed of strontium and Iron oxide (SrO . 6Fe2O3) and offer solid performance with their low cost, higher coercive force than alnico and low recoil permeability. They are widely used for loudspeakers, small motors, generators, and rotors.
