Adsorption Structure and Selectivity of Phenols in Water-Immersed Organomontmorillonite Investigated by Molecular Simulation.

Langmuir

January 2025

Department of Environmental Chemistry and Chemical Engineering, School of Advanced Engineering, Kogakuin University, 2665-1 Nakano, Tokyo, Hachioji 192-0015, Japan.

The two-dimensional interlayer space of layered materials has been highlighted due to their adsorption property, whose nanostructure in the water-immersed state is scarcely understood by experiment. Recent developments in molecular simulation have enabled researchers to investigate the interlayer structure, but water content is necessary for accurate modeling. In the present study, we proposed a theoretical method to estimate the saturated water content and adsorption selectivity of trichlorophenol and phenol in montmorillonite modified with hexadecyltrimethylammonium ions.

The industrial application of polymer electrolyte membrane fuel cells is limited by the high cost of platinum catalysts. In this study, we developed a one-step synthesis strategy for low-platinum alloy catalysts based on crystal-structure predictions. Using this method, we successfully prepared a low-platinum alloy catalyst, i.

Influence of Co Doping on Copper Nanoclusters for CO Electroreduction.

ACS Omega

November 2024

Centro Federal de Educação Tecnológica de Minas Gerais, CEFET-MG, Av. Amazonas 5253, 30421-169 Belo Horizonte, Minas Gerais, Brazil.

Article Synopsis
  • - Copper is unique in its ability to reduce carbon dioxide beyond carbon monoxide and formic acid, with substitutional doping in nanoclusters promising to improve its catalytic performance.
  • - This study examines cobalt doping in copper nanoclusters using advanced computational methods, revealing that substituting a copper atom with cobalt significantly alters the electronic properties of the material.
  • - The presence of cobalt enhances the adsorption strength of reaction intermediates, promotes the formation of more valuable products like methane and methanol, and reduces the risk of catalyst poisoning, although it may also increase hydrogen production in competing reactions.

Metal-Free N, P-Codoped Carbon for Syngas Production with Tunable Composition via CO Electrolysis: Addressing the Competition Between CO Reduction and H Evolution.

ChemSusChem

November 2024

Division of Chemical Engineering, Department of Materials Engineering Science Graduate School of Engineering Science, Osaka University, 1-3 Machikaneyama, Toyonaka, Osaka 560-8531, Japan.

Electroreduction of carbon dioxide into value-added fine chemicals is a promising technique to realize the carbon cycle. Recently, metal-free heteroatom doped carbons are proposed as promising cost-effective electrocatalysts for CO reduction reaction (CORR). However, the lack of understanding of the active site prevents the realization of a high-performance electrocatalyst for the CORR.

Article Synopsis
  • Artificial organs like oxygenators and dialyzers struggle with uneven flow distribution, leading to clot formation and reduced efficiency.
  • This study introduces triply periodic minimal surfaces (TPMS) to enhance flow distribution and examines their impact on blood coagulation through computational fluid dynamics and blood testing.
  • Results show that TPMS, especially anisometric designs, improve flow distribution and significantly reduce blood clotting compared to traditional tubular designs, while also allowing for customizable inner surfaces for better functionality.
