Promoting Homogeneous Interfacial Li+ Migration by Using a Facile N2 Plasma Strategy for All-Solid-State Lithium-Metal Batteries

Zhengyin Yao et al.

Summary: This study proposes a facile strategy to promote homogeneous interfacial Li+ migration by modifying hybrid solid electrolytes (HSEs) using nitrogen plasma. The modified HSEs exhibit an ultra-stable and conductive Li3N layer on the surface, which improves Li+ transfer dynamics and homogeneous deposition. Experimental results show that the HSE modified by nitrogen plasma has low interfacial impedance and high Li+ conductivity, demonstrating good stability and the ability to achieve electrode deposition and stripping without Li dendrite growth.

Pressurized physical activation: A simple production method for activated carbon with a highly developed pore structure

Hyeonseok Yi et al.

Summary: Activated carbon is produced by physical or chemical activation methods. While physical activation methods are commonly used in industry due to lower production costs, they are less effective compared to chemical activation methods in terms of pore development. A novel pressurized physical activation method is proposed to increase activating agent diffusibility and pore development, resulting in activated carbon with higher specific surface area and unique pore size distribution.

Titanium dioxide as support material for Pt1Pd3 toward methanol oxidation

Mengmeng Xu et al.

Summary: The electrocatalytic oxidation of methanol on Pt1Pd3 nanoparticles supported on rutile TiO2 in alkaline solution shows higher catalytic activity and CO tolerance compared to other catalysts like Pt/TiO2 and Pd/TiO2. The synergy between Pt1Pd3, Pt, Pd, and TiO2 plays a crucial role in enhancing catalytic performance and stability. Rutile TiO2 is proven to be a suitable support material for Pt1Pd3, contributing to improved catalytic activity.

Synthesis of Platinum Nanoparticles by Plasma Sputtering onto Glycerol: Effect of Argon Pressure on Their Physicochemical Properties

V Orozco-Montes et al.

Summary: Platinum nanoparticles were synthesized in glycerol using magnetron sputtering method at different argon pressures and deposited onto a carbon substrate to form catalysts. Molecular dynamics simulations revealed the dependency of Pt nanoparticles growth on argon pressure and kinetic energy of Pt atoms. Characterization using small-angle X-ray scattering showed the presence of two populations of nanoparticles with different sizes, influenced by the deposition conditions and pressure.

Single-atom catalyst for high-performance methanol oxidation

Zhiqi Zhang et al.

Summary: In this study, Pt single atom supported on RuO2 exhibits highly active methanol oxidation compared to Pt single atom supported on carbon. The newly synthesized Pt-1/RuO2 catalyst shows significantly improved mass activity for methanol oxidation in alkaline media, surpassing most previously developed Pt-based catalysts. Additionally, Pt-1/RuO2 demonstrates high tolerance to CO poisoning and excellent catalytic stability, with the presence of unique Pt-O-3f-Ru-cus bonds contributing to lower energy barriers for the electrochemical dehydrogenation of methanol.

Sulfur stabilizing metal nanoclusters on carbon at high temperatures

Peng Yin et al.

Summary: Sulfur-doped carbon support can stabilize metal nanoclusters at high temperatures, enhancing adhesion strength and retarding metal atom diffusion and nanocluster migration. The sulfur-doped carbon supported Pt nanocluster catalyst exhibits higher selectivity and more stable durability in catalyzing propane dehydrogenation at 550 degrees C compared to sulfur-free carbon supported catalysts.

Physical and chemical activation mechanisms of carbon materials based on the microdomain model†

Inchan Yang et al.

Summary: The physical and chemical activation mechanisms of carbon materials were investigated, with physical activation involving non-selective removal of carbon from the surface of carbon particles, and chemical activation selectively removing non-graphitic parts. High activation temperatures are needed for physical activation to obtain highly porous carbon, while low temperature chemical activation rapidly converts carbon particles into highly porous activated carbon.

Plasma tailored reactive nitrogen species in MOF derived carbon materials for hybrid sodium-air batteries

Xiecheng Yang et al.

Summary: The catalytic activity of metal-organic framework derived N-doped carbon nanotubes can be enhanced by changing the relative contents of Co-N-x sites, Co-Co bonds, and pyridinic-N through low-temperature plasma treatment. Adjusting the composition of pyridinic-N, Co-N-x sites, and Co-Co bonds in the nanotubes improves the efficiency of the oxygen reduction reaction and oxygen evolution reaction. This modification leads to improved performance in hybrid sodium-air batteries, with low overpotential and excellent round trip efficiency.
