Summary: In this study, Fe(III) ions were incorporated into TiO2 hollow submicrospheres, which served as an excellent photocatalyst. The experimental parameters such as flow rate, rotation speed, and contaminant concentration were found to improve the catalyst activity. Fe-TiO2 hollow submicrospheres with different Fe wt% were prepared, and it was discovered that 2.5 wt% Fe-TiO2 exhibited the best photocatalyst activity. The Fe(III) doping not only increased the interaction between transition metal (Fe and Ti) 3d orbitals in TiO2, but also promoted the Fe(III)/Fe(II) redox kinetics and the associated photo-Fenton degradation of acetaminophen.

Summary: Carbon@titania yolk-shell nanostructures are successfully synthesized and used as a photocatalyst to degrade acetaminophen. The presence of residual carbon nanospheres is found to improve the photocatalytic efficiency. X-ray absorption spectroscopy analysis reveals the structural and electronic changes in the hollow shell. In situ XAS measurements show that the existence of amorphous carbon nanospheres inhibits the recombination of electron-hole pairs, leading to enhanced photodegradation of acetaminophen. Charge transfer from TiO2 to carbon nanospheres reduces electron-hole recombination and increases photocatalytic efficiency.

Summary: Energy conversion from chemical to electrical energy through electrochemical processes using fuel cells is a promising advanced technology to address global environmental issues. However, the development of cathode materials for proton exchange membrane fuel cells (PEMFCs) still faces challenges due to their practical requirements for activity and stability. Introducing oxides into the electrocatalysts is an important way to improve performance. Therefore, hybrid metal-oxide-carbon materials with high conductivity, electronic interaction, and carbon corrosion resistance are strongly recommended as support materials for Pt nanoparticles to develop Pt-based electrocatalysts for fuel cell applications.

Summary: This study investigates the influence of fluoroethylene carbonate (FEC) and lithium difluorophosphate (LiPO2F2) dual additives on the cycling stability of lithium metal batteries using in situ diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS). The results show that the presence of these additives can suppress the formation of SEI species on the copper anode, improving the cycling stability. LiPF6 reacts with the copper anode to form LixPFy, leading to a reduction peak at approximately 1.44V in constant voltage (CV) analysis. FEC leads to the continuous formation of poly(FEC) during the first lithiation cycle, while EC and DEC are electrochemically reduced to (CH2OCO2Li)2 and Li2CO3. The redox of LiPO2F2 and the decomposition of LiPF6 are partly suppressed by the presence of FEC.

Summary: The development of next-generation rechargeable lithium-metal batteries (LMBs) is crucial for improving the performance of existing lithium-ion batteries. However, uncontrollable lithium dendrite growth and unstable solid electrolyte interphases (SEI) in lithium-metal anodes limit their practical applications. A study found that magnesium (Mg) doping on the Li anode may aid in the formation of a stable SEI layer, improving the electrochemical performance of LMBs. In this study, ab initio molecular dynamics (AIMD) simulations were used to investigate the interfacial reactions between the electrolytes and the Mg-doped Li metal anode surface. The results showed that the Mg-doped lithium anode promoted the decomposition of LiPF6 and solvents, leading to the formation of a denser SEI layer.
