Summary: This study investigates the effects of perovskite-structured Pr0.4Sr0.6Co0.2Fe0.8O3-delta (PSCF) modification on the electrochemical performance of La1-xSrxCo1-yFeyO3-delta (LSCF) cathodes using experimental and theoretical methods. The results show that PSCF modification reduces the formation energies of oxygen vacancies, lowers the adsorption energies of oxygen adsorption on the LSCF surface, and greatly decreases the dissociation barriers of oxygen molecules on the LSCF surface. These changes result in a significant improvement in the rate of oxygen reduction reaction and the activation of the LSCF surface with PSCF modification, leading to enhanced performance of the cathode.

Summary: Effective capture and utilization of CO2 is critical for reducing greenhouse gas emissions and achieving a low-carbon economy. In this study, bismuth oxides with different crystallized phases (alpha, beta, delta, gamma) were synthesized and used as photo, thermal, and photothermal catalysts for the carbonylation of isobutyl amine with CO2. The results showed that the alpha-Bi2O3 exhibited the highest catalytic performance, with a conversion of 50.38% and a selectivity of 91.79% for N,N'-diisobutylurea. Further characterization of Bi2O3 polymorphs revealed that the differences in photothermal catalytic activity could be attributed to the efficiencies of photoinduced carriers separation.

Summary: The article explores the importance of mass transfer in catalytic processes, specifically in the electrocatalytic oxygen reduction reaction (ORR) by tailoring the pore sizes. By employing a confined-etching strategy, boron-and nitrogen-doped carbon (B,N@C) electrocatalysts with abundant active sites but different porous structures were fabricated. The ORR performance was found to be correlated with reactant diffusion, with the optimized B,N@C catalysts featuring trimodal-porous structures demonstrating enhanced O2 diffusion and improved activity per heteroatomic site. The study highlights the significance of nanoarchitecture engineering in catalysts and provides insights into optimizing structures with abundant active sites and enhanced mass transfer.

Summary: In this paper, the authors study the characteristics of chromium evaporation, oxide scale growth, and deposition of chromium on the oxygen reduction reaction (ORR) on (La,Sr)MnO3 (LSM) cathode in intermediate-temperature solid oxide fuel cells. The results indicate that the volatilization of chromium is influenced by the composition and morphology of the oxide scale, and the deposition of chromium on the LSM cathode degrades the electrochemical activity of the ORR. These findings provide insights into the mechanism of chromium poisoning in intermediate-temperature conditions.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
