  • Publication number: 20240352605
    Abstract: A method for making a catalyst comprises providing an initial compound having a perovskite lattice structure according to formula I M1M2M3O3 ??FORMULA I, where M1 is about 1 relative elemental ratio strontium (Sr); M2 is from greater than 0 to 0.7 relative elemental ratio and is selected from cobalt (Co), scandium (Sc), iron (Fe), nickel (Ni), and titanium (Ti); and M3 is 0.3 to 0.6 relative elemental ratio iridium (Ir). Initial exemplary compounds include SrSc0.5Ir0.5O3 (SSI) and SrCo0.5Ir0.5O3 (SCI). M1 and/or M2 cations are selectively leached from the initial compound to produce a catalyst having substantially increased catalytic performance. Cycling SSI or SCI in an acid produces SSI-H or SCI-H; cycling SSI or SCI in a base produces SSI-OH or SCI-OH. Dual-site metal leaching induced catalytic activity improvement by about 2 orders of magnitude, making reconstructed SrCo0.5Ir0.5O3 among the best-known catalysts for water oxidation in an acidic condition.

  • Publication number: 20210273268
    Abstract: A rechargeable battery is provided. The rechargeable battery includes an anode, a cathode, an electrolyte in contact with the anode and the cathode, and an interlayer disposed between the anode and the cathode in the electrolyte. The anode is configured to allow growth of one or more dendrites in a direction from the anode to the interlayer to electronically couple the anode to the interlayer, wherein the interlayer is configured to electrochemically react with cations present in the electrolyte upon formation of the electronic coupling between the anode and the interlayer, thereby inhibiting the growth of the one or more dendrites in a direction from the interlayer to the cathode. An interlayer disposable between the anode and the cathode in the electrolyte of a rechargeable battery is also provided. The interlayer inhibits growth of the one or more dendrites in a direction from the interlayer to the cathode.
