Preparation and bifunctional properties of the A-site-deficient SrTi_0.3Fe_0.6Ni_0.1O_3−δ perovskite

Abstract

The development of efficient, non-noble metal electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is crucial for their application in energy storage devices, such as fuel cells and metal–air batteries.

Strategic Design and Insights into Lanthanum and Strontium Perovskite Oxides for Oxygen Reduction and Oxygen Evolution Reactions

“…The ZAB performance of Sr 0.9 Ti 0.3 Fe 0.6 Ni 0.1 O 3−δ demonstrated a power density of ≈135 mWcm −2 , which was better than Pt/C. [ 156 ] Subsequently, (Pr,Sr) 2 Ni 0.5 Co 0 .5O 4−δ / PrNi 0.5 Co 0.5 O 3−δ (RP‐PSNC/PPNC) heterostructured nanofibers were synthesized by a simple impregnation method. It is noted that the two phase interface of Ruddlesden‐Popper perovskite (RP‐PSNC) and perovskite (PPNC) created a number of vacancies.…”
