The pseudomorphic-Pt atomic layer epitaxially growing on an IrPd-core matrix (PmPt@IrPd/C) exhibits significantly enhanced mass activity and stability compared to benchmark Pt/C. The improved stability is attributed to resistance to carbon corrosion and modulated hydroxyl adsorption.

Summary: To address the issues of Ni-rich NCM, Al (CF3SO3)(3) was proposed as a solid electrolyte additive to regulate the CEI in single-crystalline NCM811. The facile oxidation of CF3SO3- and subsequent reactions with reactive species from NCM811 and electrolyte lead to the formation of a robust sandwich CEI film containing sulfur and aluminum species. This CEI film not only prevents electrolyte decomposition but also alleviates the formation of inactive rock-salt phase on NCM811 surface, resulting in a high-capacity retention of 91.5% after 200 cycles under 0.5 C.

Summary: In this study, a novel ternary NASICON Na3.8MnV0.8Zr0.2(PO4)(3) was successfully synthesized and tested as a cathode material for rechargeable sodium-ion batteries. By partially substituting Zr4+, the obtained Na3.8MnV0.8Zr0.2(PO4)(3) exhibited a high capacity retention of 83.5% after 1000 cycles at 2 C, and impressive rate capacities of 73.1 mAh g(-1) at 20 C and 66.8 mAh g(-1) at 60 C. The enhanced rate capability can be attributed to the widened Na-ion channels and high Na-ion diffusivity. Additionally, the low volume expansion during Na-ion extraction contributes to the structural integrity over cycling. This work paves the way for the development of greener, high-power, and long-life sodium-ion batteries.

Summary: For the catalyst SAPO-34 used in the conversion of methanol to light olefins, micropores that promote higher light olefins selectivity are susceptible to blockage by coke, leading to fast catalyst deactivation. Alkali post-treatment was employed to introduce secondary mesopores and improve mass transfer, resulting in longer catalyst lifetime but slightly lower light olefins selectivity. The formation of heavier coke species over the treated catalysts was related to the alteration in active sites, with Lewis acid sites remaining intact while Bronsted acidity was depleted.

Summary: The electrochemical reduction of nitrate (NO3RR) has attracted significant attention as a promising route for ammonia synthesis and addressing nitrate pollution. Developing catalyst materials with high activity and selectivity is crucial for improving the efficiency of this process. While copper and copper-based catalysts have been extensively studied, the reasons for their high activity and selectivity have been less explored. In this study, Density Functional Theory (DFT) is used to identify reactivity descriptors and explain why copper is the most active and selective transition metal for the NO3RR to ammonia among ten different transition metals. The NO3RR selectivity is also assessed by considering the competition with the hydrogen evolution reaction, and multiple approaches for developing highly active catalyst materials for the NO3RR are proposed.
