“…Liu et al synthesized four types of CMPs by Suzuki coupling reaction followed by crosslinking with HCPs by Friedel‐Craft alkylation. [ 90 ] The Suzuki coupling reactions were catalyzed by a palladium catalyst (Pd(PhCN) 2 Cl 2 ) to form four different types of CMPs. The reaction took place at 120°C for 3 days in the solvent phase (using dimethylformamide).…”

Intrinsic structural characteristics of porous materials have found significant applications in selective separation of gases and heterogeneous catalysis. While using porous materials for gas separation and catalysis, some of the challenging issues are the strength of catalytic sites, hydrothermal stability, crystalline order of solids, and selectivity. Researchers' ability to engineer the synthesis strategies rationally can help overcome technological challenges. In recent years, breakthroughs in porous materials are focused on developing different chemistries to control the pore architecture. This review focuses on recent advances made in synthesis strategies of porous materials and their impact on gas separation and catalysis applications. A significant part of this review is devoted to various synthesis methods, such as various types of templating methods, molecular layer deposition, sol-gel technique, and polymerization methods. Improvement in various catalytic reactions and gas separations due to different functionalization methods is also summarized. Lastly, we have discussed the applications of porous materials in the form of adsorbents and membranes in commercial processes. We hope that this review will serve as a quick reference for beginners who want to synthesize porous materials with control of pore structure.

To obtain high purity of natural and flue gases, the development of adsorbent with appropriate structure is of great importance. As a result, there is an urgent need to investigate the role of aromatic ring spacer in adsorbent in high CO 2 capture. For this, conjugated microporous polymers (CMPs) were fabricated through homo-coupling reaction of 1,3,5-tribromobenzene (TBB) and 1,3,5-triethynylbenzene (TEB). It was observed that, CMP-A (without spacer) demonstrates high CO 2 uptake over CMP-B (with spacer). CMP-A demonstrates CO 2 uptake of 212.1 mg g À1 which is obviously higher than benchmark adsorbents under the analogous conditions. In addition, the obtained CO 2 uptake is also higher than metal-organic framework (MOF) and energyintensive carbon-based adsorbents. CMP-A revealed high CO 2 /N 2 selectivity (78.5) over CMP-B (56.1). It was noticed that CMP-A demonstrates excellent CO 2 /CH 4 and CO 2 /N 2 selectivity over CMP-B at 273 K. This is mainly due to appropriate structure in CMP-A (without spacer). The obtained CO 2 /N 2 selectivity (78.5) is higher than recently reported adsorbents under the similar experimental conditions.

“…First, a combination of fine-tuned pore sizes, well-defined adsorptive sites, and remarkable physicochemical stability makes PCPs excellent materials for gas separation and storage. [15][16][17] It has been demonstrated that the adsorption capacity and selectivity can be improved by nanopore size engineering and the introduction of heterocycles or CO 2 -philic functional groups, [18][19][20][21] etc. In addition, PCPs have been proven to be a promising platform for CO 2 photoreduction because their electronic structures and band positions can be fine tuned at the molecular level to meet the requirements for artificial photosynthetic production of CO and hydrocarbons.…”

Herein, three 1,3,5‐triphenylbenzene based porous conjugated polymers (PCPs) are designed for photochemical reduction of CO2 in simulated flue gas in the mild gas−solid reaction system. By tuning the nature of the comonomers, the PCPs present high surface areas, high CO2/N2 selectivity, and broad visible light absorptions with bandgaps of 1.81−2.07 eV. At 1 bar and 273 K, the CO2 uptake capacity of PCPs is enhanced from 1.28 to 2.18 mmol g−1, with an increase in CO2 adsorption heat from 21.8 to 28.3 KJ mol−1. In the presence of gaseous water, SO‐TPB demonstrates the highest CO production rate of 40.12 μmol h−1 g−1 and nearly 100% product selectivity without using organic sacrificial reagent and additional cocatalyst (>420 nm). Moreover, SO‐TPB can be recovered while well retaining the photocatalytic activity and reused at least five runs, indicating good recyclability.
