Summary: A dual-layer interphase consisting of an in-situ-formed lithium carboxylate organic layer and a thin BF3-doped monolayer Ti3C2 MXene on Li metal is reported. The honeycomb-structured organic layer increases the wetting of electrolyte, leading to a thin solid electrolyte interface (SEI). The BF3-doped monolayer MXene provides abundant active sites for lithium nucleation and growth, reducing the thickness of inorganic-rich components in the SEI layer.

Summary: Prelithiation has a significant impact on the electrochemical performance of lithium-ion batteries and hybrid supercapacitors (HSC). This study investigates HSCs made with prelithiated porous CaFe2O4 (pCFO) anodes at different degrees. Prelithiation affects the anode morphologies and compositions predictably, but has a more stochastic influence on HSC performance. Surprisingly, pCFO-based HSCs show competitive energy and power density, as well as long-term cycling stability, indicating that pCFO may be a promising candidate for next-generation HSCs.

Summary: Enhancing the activity of non-precious metal catalysts for low-temperature degradation of volatile organic compounds (VOCs) has always been a topic of interest. This study successfully adjusted the Ce-O bond strength in CeZr oxide catalysts by cobalt doping, leading to improved toluene degradation performance while maintaining high stability. The weakening of the Ce-O bond strength increased the oxygen vacancy content, promoted the activation of oxygen species, and enhanced the redox ability of the catalysts, ultimately resulting in enhanced VOCs degradation performance.

Summary: In this study, tungsten-acidified and sulfated CeO2 catalysts were prepared, and operando spectroscopy was used to understand the dynamics of acid sites and redox sites on the catalysts during NH3-SCR reaction. It was found that both Lewis and Bronsted acid sites are necessary for the catalytic reaction, with Bronsted acid sites being the main active sites after treatment. The change of Bronsted acid sites significantly affects the removal of nitrogen oxides. Acid functionalization also promotes the cycle of cerium species for NOx reduction. This work is crucial for understanding the nature of active sites and provides new insights into the mechanism of NH3-SCR over CeO2-based catalysts.

Summary: This study proposes magnesium-doped layered manganese dioxide (Mg-MnO2) as cathode materials for aqueous zinc-ion batteries (ZIBs) to improve their performance. Mg-MnO2 with a larger specific surface area provides more electroactive sites and enhances the capacity of ZIBs. The electrical conductivity and ion diffusion coefficients of Mg-MnO2 are also improved by doping cations and oxygen vacancies in the MnO2 lattices. The assembled Zn//Mg-MnO2 battery exhibits a high specific capacity and reversible redox reaction between Zn2+ and MnOOH, promoting capacity and stability.

Summary: The use of catalysts is crucial for reducing emissions and improving sustainability in industrial processes. However, the poisoning of catalysts by alkali and heavy metals can limit their effectiveness and increase environmental impacts. This study proposes a precise regeneration approach for metal-poisoned catalysts, using the Sabatier principle and formic acid, which showed high removal efficiency for metal poisons and retention of active species. This approach not only extends the catalysts' lifetime, but also reduces the environmental impact of spent catalyst disposal.

Summary: This study demonstrates NOx reduction against sulfur poisoning using Ce-modified Cu-SAPO-34 catalysts. The catalyst modified with 0.5 wt% Ce shows remarkable sulfur tolerance during NH3-SCR of NOx. The SCR performance of the sulfur-poisoned catalysts is significantly improved due to the positive role played by Ce in reducing deposited sulfate species. The Cu-SAPO-34 catalyst incorporating 0.5 wt% Ce can maintain more active Cu2+ after sulfur poisoning due to enhanced binding of Cu2+ ions to the SAPO-34 framework. This work paves the way for the development of highly efficient catalysts against sulfur poisoning for NOx reduction.
