Abstract The electrochemical reduction of carbon dioxide (ERCO 2 ) to chemical feedstock and fuels is a promising strategy for reducing excessive emissions. There are various benefits converting CO single product Pb one the active efficienct catalyst HCOOH. current work used electro‐deposition method produce manganese oxide (Mn 3 O 4 (nano particle flakes) highly active, low‐cost lead (Pb) catalysts with variety morphologies (Nano crystal Flakes, Nano wires, sheets). For first time, Mn was employed as anode in water oxidation process protons, electrocatalytic effects on ERCO reaction were investigated. influence loading investigated lone HCOOH detected produced catalysts. Using systematic study, final identified measured. maximum Faradaic efficiency measured at −1.003 V, yielding 77.32 % (10 min) 1 mg/cm 78.4 nano wires V loading, respectively. More specifically, it discovered that selectivity electroreduction influenced by morphology catalyst. These results provide an intimate understanding

Organic and Metal–Organic Polymer-Based Catalysts—Enfant Terrible Companions or Good Assistants?

Molecules, Journal Year: 2024, Volume and Issue: 29(19), P. 4623 - 4623

Published: Sept. 29, 2024

This overview provides insights into organic and metal–organic polymer (OMOP) catalysts aimed at processes carried out in the liquid phase. Various types of polymers are discussed, including vinyl (various functional poly(styrene-co-divinylbenzene) perfluorinated functionalized hydrocarbons, e.g., Nafion), condensation (polyesters, -amides, -anilines, -imides), additional (polyurethanes, polyureas, polybenzimidazoles, polyporphyrins), prepared from organometal monomers. Covalent frameworks (COFs), (MOFs), their composites represent a significant class OMOP catalysts. Following this, preparation, characterization, application dispersed metal discussed. Key catalytic such as alkylation—used large-scale applications like production alkyl-tert-butyl ether bisphenol A—as well reduction, oxidation, other reactions, highlighted. The versatile properties COFs MOFs, well-defined nanometer-scale pores, large surface areas, excellent chemisorption capabilities, make them highly promising for chemical, electrochemical, photocatalytic applications. Particular emphasis is placed on potential CO2 treatment. However, notable drawback COF- MOF-based relatively low stability both alkaline acidic environments, high cost. A special part devoted to deactivation disposal used/deactivated catalysts, emphasizing importance separating heavy metals conclusion guidance selecting developing OMOP-based
