Summary: The increasing demand for electric vehicles and smart grids has greatly improved the comprehensive function of lithium-ion batteries (LIBs). However, the commercial graphite used as an important part of LIBs is not suitable for fast-charging due to its sluggish Li+ diffusion rate, thermal runway, and volume expansion. Here, nano-sized Nb14W3O44 blocks are synthesized as a fast-charge anode material, which provides a shorter Li+ diffusion pathway and accelerates the diffusion rate. The Nb14W3O44 exhibits excellent long-term cycling life and rate capability, and it is recognized as a promising fast-charge anode material for next-generation LIBs.

Summary: This study proposes a new method to construct a high-performance cathode for fast-charging lithium-ion batteries, by utilizing a fully supported lattice network and a self-passivating surface. By one-step solid-phase sintering of Sn and S co-doped LCO, a fully supported lattice network is formed, reducing the energy barrier of Li+ transport and promoting Li+ solid-state diffusion. In addition, the self-passivating surface formed on LCO-Sn0.6 significantly enhances the adsorption energy of EC and LiPF6, forming effective CEI membranes and enabling high capacity and SOC after extremely fast charging.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
