“…To circumvent this issue, efforts have been devoted to the heterogenization of organometallic catalysts on a variety of porous solid materials. For example, salen‐based complexes were incorporated into microporous polymers through copolymerization with another nonpolar monomer in the presence of a metal catalyst, and the materials exhibited excellent activities and recyclabilities in CO 2 cycloaddition reactions owing to the stability of the polymer structure and the enrichment of CO 2 in the nanopores . Despite this significant progress, there is still room for improvement.…”

As a C feedstock, CO has the potential to be uniquely highly economical in both a chemical and a financial sense. Porous materials bearing particular binding and active sites that can capture and convert CO simultaneously are promising candidates for CO utilization. In this work, a bipyridine-constructed polymer featuring a high surface area, a hierarchical porous structure, and excellent stability was synthesized through free-radical polymerization. After metalation, the resultant catalysts exhibited superior activities in comparison with those of their homogeneous counterparts in the cycloaddition of CO to epoxides. The high performance of the heterogeneous catalysts originates from cooperative effects between the CO -philic polymer and the embedded metal species. In addition, the catalysts showed excellent stabilities and are readily recyclable; thus, they are promising for practical utilization for the conversion of CO into value-added chemicals.

“…MOFs with their hybrid, non‐noble metal composition are actively being investigated as catalysts or catalyst supports for energy applications . MOFs commonly demonstrate numerous unique characteristics including: permanent porosity, high surface area, controlled pore size and tunable framework, and/or guest functionalities . Therefore, the recent rapidly growing interest in MOFs, as well as other types of microporous solids, as catalysts for several energy‐storage reactions is vindicated…”

The recent progress and challenges in developing highly active microporous materials as heterogeneous electrocatalysts for oxygen reduction reaction (ORR) are discussed. Due to the slow kinetics of ORR, the search for novel highly stable catalysts that can outperform Pt‐based ones is a growing demand. Functional microporous materials and exceptional chemical stability are of great interest due to their unique catalytic properties. The crucial rule of porosity and catalyst design strategies are thoroughly discussed with emphasis on the influence of the degree of microporosity on the material's intrinsic catalytic activity and the current best practice for catalyst testing and activity reporting. This Review focuses on microporous materials, which are classified into crystalline as metal–organic frameworks (MOFs), covalent–organic frameworks (COFs), or amorphous porous–organic polymers (POPs) as to their recent utilization in constructing efficient ORR electrocatalysts. The fundamental challenges in obtaining stable catalysts with appreciable kinetics from non‐noble metal ions, and ways to form them utilizing microporous solids as catalyst matrices, are reviewed. The fundamental criteria for future generation ORR catalysts based on microporous solids, including stability in acidic medium, high electrical conductivity, and accessibility of the active sites within the matrix are highlighted for guidance to future works.

Development of inexpensive, easily prepared, non-toxic, and efficient catalysts for the cycloaddition of CO with epoxides to synthesize five-membered cyclic carbonates is a very attractive topic in the field of CO transformation. In this work, we conducted the first work on the cycloaddition of CO with epoxides to produce cyclic carbonates catalyzed by a binary catalyst system consisting of KI and boron phosphate (BPO ), which are both inexpensive and non-toxic, and various corresponding cyclic carbonates could be produced with high yields (93-99 %) at 110 °C with a CO pressure of 4 MPa under solvent-free conditions. In the BPO /KI catalyst system, BPO , a Brønsted and Lewis acid hybrid, played the role of activating the epoxy ring through the formation of hydrogen bonds with Brønsted acidic sites and the interaction with Lewis acidic sites simultaneously, and thus enhanced the activity of KI for the cycloaddition of CO with epoxides significantly. Additionally, the activity of the BPO /KI catalyst system showed no noticeable decrease after being reused five times, indicating that the BPO was stable under the reaction conditions.
