Quantitative Determination of Metal Center Coordination Numbers in Resin‐Based Supported Catalysts via CO2 Adsorption
Year: 2024
Type: article
Abstract: ABSTRACT A novel method was described for quantitatively determining the metal centers' average coordination numbers in as‐prepared supported metal catalysts using polyamine‐modified resin carriers via CO2 adsorption. Using porous resin (PS) and pentaethylenehexamine (PEHA) as starting materials, a new polyamine‐modified resin carrier PS‐PEHA was obtained to anchor various metals (Cu, Pd, Co, Ni, and Zn), thereby preparing a range of supported catalysts. The structures of the metal catalysts were characterized through FT‐IR, XPS, SEM, EDS, BET, and ICP‐OES. DVS was employed to study the carrier and catalyst performance of CO2 adsorption. The average coordination numbers of the metal centers were quantitatively determined based on their differences in CO2 adsorption capacities. The coordination numbers determined were Co (3.5), Ni (3.5), Pd (4.8), Zn (3.6), and Cu (5.9).
