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
