Electrodes functionalized with molecularly well-defined reactive/catalytic species have become attractive for promoting a wide variety of electrochemical energy conversion processes or systems, such as electrocatalytic CO 2 and O reduction, well metal-sulfur redox-flow batteries. 1-3 Critical to the performance these electrodes is interaction between electric field, molecular at electrical doub...

A silver-deposited nickel (Ag/Ni) wire electrode was prepared via a galvanic replacement reaction between Ag+ and Ni in aqueous solution. It then found that the Ag/Ni could be modified with Pt simply by treating it an solution of K2PtCl4. Although deposition Ag on limited amount, forming deposits less than 100 nm size, considerable increase electrocatalytic currents for oxidation alcohols obser...

Ruddlesden–Popper type electrodes with composition La2CuO4−δ are alternative cathode materials for solid oxide fuel cells (SOFCs); however, the undoped compound exhibits low electrical conductivity potential applications, which is usually increased by alkaline-earth doping. A promising to doping modification of anionic framework halogen In this study, La2CuO4−0.5xAx (A = F, Cl, Br; x 0–0.3) com...

Oxides composed of an oxygen framework and interstitial cations are promising cathode materials for lithium-ion batteries. However, the instability under harsh operating conditions results in fast battery capacity decay, due to weak orbital interactions between (mainly 3d–2p interaction). Here, a robust endurable is created by introducing strong 4s–2p hybridization into structure using LiNi0.5M...
