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

Molecules, Год журнала: 2024, Номер 29(19), С. 4623 - 4623

Опубликована: Сен. 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

Highly Efficient and Selective Photothermal Catalytic CO₂ Reduction to CH₄ Using the CoNi Bimetallic-Modified Gd₂O₃&Co₃O₄ Nanocomposite

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(42), С. 15682 - 15695

Опубликована: Окт. 7, 2024

With the increase of CO2 in atmosphere, how to convert into fuel has become a research hotspot. Photothermal catalysis is quite promising method obtain CH4 via Sabatier reaction. In this context, it urgent design efficient catalysts improve conversion and selectivity aqueous CH4. work, CoNi/(Gd2O3&Co3O4) nanocomposite was fabricated calcination chemical deposition methods. Compared with Gd2O3 Co3O4, 80%-CoNi/(Gd2O3&Co3O4) shows an enhancement photothermal catalytic evolution rate (4.19 mmol g–1 h–1) high for (98.6%). addition, sample also possesses outstanding durable cyclic stability. Combined systematic analysis, found that excellent performance can be attributed two main reasons: (i) dual-heterostructure formation P–N Schottky junction endows catalyst charge separation efficiency (ii) presents preeminent adsorption redox capacities, which greatly improves its activity. This study significant advantages resource utilization sustainable catalysts.

Ultrathin PdAu Nanowires with High Alloying Degree for the Direct Oxidation of Methane to C1 Oxygenates

Chinese Journal of Chemistry, Год журнала: 2024, Номер 42(23), С. 2999 - 3005

Опубликована: Авг. 21, 2024

Comprehensive Summary The direct oxidation of methane (CH 4 ) into high‐valued C1 oxygenates production has garnered increased attention in effectively using vast CH and alleviating the global energy crisis. However, due to high cleavage C—H bond low polarity molecule, it is difficult activate first bond. Furthermore, are readily inclined be oxidized CO 2 , because their weaker comparing with resulting poor selectivity. Herein, we designed ultrathin Pd x Au y alloy NWs supported on ZSM‐5 (Z‐5) investigate value‐added oxygenate under mild conditions. By precisely adjusting molar ratio Pd/Au alloying degree, 9 1 NWs/Z‐5 showed an excellent yield 11.57 mmol·g –l ·h –1 outstanding selectivity 95.1% for 3 OH, OOH HCOOH). in‐situ spectroscopic mechanism analysis proved that enhanced catalytic performance was ascribed stable one‐dimensional nanostructure strong synergy effect PdAu, which could increase adsorption capacity molecules atoms promote conversion. This work offers valuable insights design concept high‐efficient catalysts structure‐activity relationship .
