Enhancing Efficiency and High-Value Chemicals Generation through Coupling Photocatalytic CO2 Reduction with Propane Oxidation
ChemSusChem. 2024 Mar 11:e202301881. doi: 10.1002/cssc.202301881. Online ahead of print.ABSTRACTConversion of CO2 into high-value chemicals using solar energy is one of promising approaches to achieve carbon neutrality. However, the oxidation of water in the photocatalytic CO2 reduction is kinetically unfavorable due to multi-electron and proton transfer processes, along with the difficulty in generating O-O bonds. To tackle these challenges, this study investigated the coupling reaction of photocatalytic CO2 reduction and selective propane oxidation using the Pd/P25 (1 wt%) catalyst. Our findings reveal a significant impr...

A Porphyrinic Metal-Organic Framework with Cooperative Adsorption Domains for PFAS Removal from Water
ChemSusChem. 2024 Mar 11:e202400069. doi: 10.1002/cssc.202400069. Online ahead of print.ABSTRACTThe removal of toxic poly- and perfluoroalkyl substances (PFAS) as persistent pollutants from wastewater is imperative but challenging for water remediation. Many adsorbents including activated carbon, biochar, and clay minerals have been investigated for PFAS removal, but most of these materials are faced with high cost or/and low efficiency. The use of metal-organic frameworks (MOFs) as sorbents is attractive for efficient removal of PFAS due to their tailor-made structures and high surface areas. Herein, we synthesized, chara...

Recycling of Spent FCC Catalysts: Conversion of Leached Residues to Zeolite ZSM-5
ChemSusChem. 2024 Mar 10:e202301642. doi: 10.1002/cssc.202301642. Online ahead of print.ABSTRACTThe commercial recycling of spent FCC catalyst typically focuses on recovering only 1 - 3% of rare-earth elements, with the remaining residues often disposed of in landfills. Here, we present a novel method to close a recycling loop for spent FCC catalyst. The method involves a series of leaching steps: Firstly, the spent catalyst material is leached with HNO3 to remove rare-earth elements such as La; second, solvothermal leaching with HCl removes most of Al and impurities like Fe, Ni and V; finally, a third leaching with H2SO4 ...

ChemSusChem. 2024 Mar 8:e202301134. doi: 10.1002/cssc.202301134. Online ahead of print.ABSTRACTEnzymatic polymerization of lignosulfonate (LS) has a high potential for various applications. Here, the effect of different ions in low concentrations on enzymatic polymerization of LS was investigated, including salt solutions consisting of mono- and dicarboxylic acids, sulfate, phosphate and chloride with sodium as counter ion. LS polymerization was followed by viscometry and size exclusion (SEC) chromatography. Interestingly, there was only a small effect of ions on the activity of the laccase on standard substrate ABTS, whil...
