Summary: Single atom alloy catalysts offer higher turnover frequencies and selectivities than monometallic catalysts. Pd embedded in Au nanoparticles was studied as a catalyst for the direct formation of H2O2 from O2 and H2 in an aqueous solution. The simulations revealed that Pd monomers facilitated H2 dissociation, while H2O2 was formed over undercoordinated Au sites. Tuning the nanoparticle composition and reaction conditions was found to enhance the selectivity towards H2O2. This approach is applicable for various hydrogenation reactions over single atom alloy nanoparticles.

Summary: In this study, a palladium binding peptide, Pd4, was used to synthesize catalytically active palladium-decorated gold (Pd-on-Au) nanoparticles and palladium-gold alloy nanoparticles (PdxAu100-x) with high nitrite degradation efficiency. The catalytic activity of Pd-on-Au NPs correlated with the surface coverage of gold, while the activity of PdxAu100-x alloy NPs varied based on palladium composition. The highest nitrite removal efficiency was achieved at 100% surface coverage for Pd-on-Au NPs and x=59 for PdxAu100-x alloy NPs.

Summary: In this study, a hierarchical and hollow nanoplate assembled by Fe-doped Co3O4 nanosheets (Fe-Co3O4 HHNPs) is designed as an advanced sulfur nanoreactor to overcome the challenges faced by lithium-sulfur batteries. The interlaced nanosheets establish a robust and porous network for fast charge transfer and efficient active site exposure. The heteroatomic Fe incorporation tailors the electronic structure, contributing to massive active sites that lower the energy barrier for sulfur conversions. The resulting sulfur adsorption and catalyzation endow the Li-S cells with high capacity retention and decent rate performance.

Summary: The rapid spread of electric vehicles with lithium-ion batteries (LIBs) poses significant challenges and environmental risks for recyclers in managing waste and after scrap. Closed-loop recycling plays a crucial role in sustaining battery development and mitigating raw material shortages and supply chain risks. This article outlines and evaluates current methods for direct cathode regeneration in industrialized recycling, summarizes different regeneration methods for spent cathode materials, providing a new perspective for closed-loop recycling of LIBs. A proposed reference recycling route for retrofitting existing cathode production lines minimizes costs. In addition to promoting the industrialization of direct cathode recycling, the article also emphasizes the environmental, economic, and political benefits of battery recycling.
