Engineering of Porous Polyamide-Supported Deep Eutectic Solvent as a Metal-Free Heterogeneous Catalyst for the Synthesis of 3,4-Dihydropyrimidinones and 5-Substituted-1H-Tetrazoles

Bifunctional covalent organic framework as a heterogeneous acid photocatalyst for solvent-free microwave-assisted synthesis of isobornyl methacrylate

Isobornyl methacrylate (IBOMA) is a bio-based specialty monomer with broad applications in coatings, adhesives, and dental materials. However, its conventional synthesis via the acid-catalyzed esterification of camphene with methacrylic acid suffers from poor catalyst recyclability, corrosive waste generation, and low...

Deep eutectic solvents for the synthesis of covalent organic frameworks: from boundaries to possibilities.

Covalent organic frameworks (COFs) are a class of crystalline porous materials assembled from discrete molecular building blocks, offering exceptional tunability and functionality that underpin their broad range of applications. However, conventional solvothermal routes for COF synthesis often rely on toxic organic sol...

Template-free and one-pot synthesis of nano-SiO2 via CO2-induced gelation for efficient and stable solid amine CO2 adsorbents

A Strategy for the Preparation of UHMWPE Featuring Self-Retardant Properties Catalyzed by a Functionalized N/P-Containing Metallocene Catalyst through In Situ Coordination Polymerization

Ultrahigh molecular weight polyethylene (UHMWPE) exhibits excellent properties such as impact resistance and abrasion resistance, but it is highly flammable and difficult to process. Traditional flame-retardant modification methods suffer from poor dispersion uniformity in the UHMWPE matrix. This study proposes an ap...

One-Pot Synthesis of Triazine-Embedded Hierarchically Porous Organosilica Polymers via Tandem Condensation for Carbon Capture and Conversion

A simple one-step route for designing three covalently bonded porous organosilica polymers via tandem condensation, bearing an adjustable triazine moiety and N–Si cooperative microenvironments, has been reported for the first time. In contrast to the traditional methods that rely on prefabricated supports or postsynt...

Engineering of Highly Dispersed [Cu(OH)] + Sites in Diverse Porous Aluminosilicates via Size-Selective Atomic Layer Deposition for Enhanced NH3-Selective Catalytic Oxidation Behaviors

The fabrication of highly uniform and dispersed catalysts is achievable through atomic layer deposition (ALD). However, the application of this method in porous materials is largely restricted by the size compatibility between the host and the guest molecules. In this study, we coupled ALD with different Cu-based cat...
