“…Thereafter, in 2021 Fariba et al proposed a method of synthesis using Schiff's base condensation only, the material was synthesized using 2,4,6-tris-(2-methoxy-4-formyl-phenoxy)-1,3,5-triazine and p-phenylenediamine (Scheme 17). 80 The surface area of this COP material was reported as 34 m 2 g À1 , which was not significantly very high, but the heteroatom-rich architect resulted in good confinement of Ag NPs. The FESEM micrographs revealed the layered and porous morphology of this material.…”

“…The specific surface area of solid supports is usually large, which greatly increases the dispersibility and stability of metal nanoparticles. Moreover, there may be interactions between particles and supports, which will further enhance the catalyst performance [108,109]. Therefore, the design and application of supported metal catalysts is an important method to improve and ensure its catalytic activity and selectivity.…”

Heterogeneous catalysis plays a central role in the chemical and energy fields, owing to the high and tunable activities of solid catalysts that are essential to achieve the favorable reaction process efficiency, and their ease of recycle and reuse. Numerous research efforts have been focused on the synthesis of solid catalysts towards obtaining the desired structure, property and catalytic performance. The emergence and development of microfluidic reactor technology provide a new and attractive platform for the controllable synthesis of solid catalysts, primarily because of its superior mixing performance and high heat/mass transfer efficiency. In this review, the recent research progress on the synthesis of solid catalysts based on microfluidic reactor technology is summarized. The first section deals with the synthesis strategies for solid catalysts, including conventional methods in batch reactors and microfluidic alternatives (based on single- and two-phase flow processing). Then, different kinds of solid catalysts synthesized in microflow are discussed, especially with regard to the catalyst type, synthetic process, structure and property, and catalytic performance. Finally, challenges in the microreactor operation and scale-up, as well as future perspectives in terms of the synthesis of more types of catalysts, catalyst performance improvement, and the combination of catalyst synthesis process and catalytic reaction in microreactors, are provided.

“…[15][16][17] It is worth noting that prudent choice of solid support in a catalytic system is crucial for obtaining the optimum conversion, greater selectivity, and extensive reusability. In this context, zeolite, [18,19] silica, [20,21] polymer, [22][23][24][25] metal oxides, [26,27] and cellulosic [28,29] supports have been tested as catalytic systems. These solid-supported catalytic systems produced excellent results in terms of reactivity and selectivity.…”

Herein, we describe a facile protocol for the phosphine complex of Rh anchored on the ultrasmall magnetic nanoparticles for transfer hydrogenation and hydroformylation reactions. A diphenylphosphino‐ferrocenylethyl amine was conjugated with dopamine hydrochloride to form dop‐Fc, which was then anchored on the surface of magnetic nanoparticles to produce Fe3O4@dop‐Fc. The prepared materials were complexed with a Rh precursor as a catalytic center. XRD, FTIR, SEM, TEM, and XPS were used to investigate the structure and its reactivity. Rh‐complexes of Fe3O4@dop‐Fc were used to convert terminal olefin to aldehyde using syngas (CO : H2 1 : 1) under pressure, obtaining up to 99% selectivity for branched aldehyde. The wide applicability of the Fe3O4@dop‐Fc−Rh construct was tested for the selective transfer hydrogenations of nitroarene and N‐heteroarene. Particularly, quinoline was quantitatively hydrogenated to 1,2,3,4‐tetrahydroquinoline(py‐THQ) using tetrahydroxydiboron (THDB). Also, the functional group tolerance in the reduction of nitroarene and styrene was evaluated. The robustness of the catalyst was tested by reusing it for multiple cycles.
