Ordered mesoporous phenolic resins and carbons - an advanced class of ultra-stable mesoporous materials - offer potential applications in the field of catalysis, electrodes and adsorbents. This review gives an extensive overview of the main principles and the recent progress made in the synthesis of these innovative materials using the soft-template method. Furthermore, the versatility towards functionalization and the incorporation of hetero-atoms in the organic framework of the mesoporous resins and carbons are considered. Finally, the broad range of potential applications is discussed and future perspectives in the field of mesoporous polymers and carbons are given.

Antibiotics are emerging environmental contaminants posing critical health risks due to their tendency to concentrate in living things and eventually infiltrate the human body. Sulfamethoxazole (SMZ) is among the commonly detected antibiotics in wastewater requiring effective removal approach. A sustainable, thermally stable and easily separable magnetic sporopollenin-cellulose triacetate (Msp-CTA) was developed via a simple step synthesis for eliminating SMZ from aqueous solution.

This report investigates the preparation, characterization, and application of activated carbon derived from Spathodea campanulata flowers (SCAC) to remove Congo Red (CR) dye from aqueous streams. SCAC was synthesized using orthophosphoric acid activation which yielded a mesoporous material with a specific surface area of (986.41 m/g), significantly exceeding values reported for flower-derived activated carbons in the available literature.

Boehmite nanoparticles and NaY nanozeolite were synthesized by co-precipitation and hydrothermal methods, respectively, and characterized by XRD, FT-IR, TG-DTA, BET, and SEM techniques. XRD and BET analyses demonstrated the formation of boehmite nanoparticles with a surface area of 350 m/g and high crystallinity NaY nanozeolite with a surface area of 957 m/g. In order to evaluate the effect of the content of the mesoporous boehmite nanoparticles on the catalytic performance of the Residue Fluid Catalytic Cracking (RFCC) catalyst, alumina active matrix-based and silica inactive matrix-based catalysts were prepared.

Given the environmental and ecological risks posed by wastewater bearing Mo, the characteristics and microscopic interactions of existing silica-based adsorbents have not been thoroughly investigated, highlighting the need to enhance the porosity and chemical interactions of these materials. Considering the effectiveness of amino groups in binding metal oxyanions, this study investigates the adsorption performance and mechanism of amino-functionalized MCM-41 for Mo(VI), with the goal of efficiently remediating Mo-contaminated wastewater. MCM-41 modified by amino group retains its original structure and mesoporous characteristics while featuring a positively charged surface and chemically bonded amino groups.

This study explores mesoporous bioactive glasses (MBGs) that show promise as advanced therapeutic delivery platforms owing to their tailorable porous properties enabling enhanced drug loading capacity and biomimetic chemistry for localized, sustained release. This work systematically investigates the complex relationship between MBG composition and surfactant templating on structural evolution, bioactive response, resultant drug loading efficiency and release. A total of 12 samples of sol-gel-derived MBG were synthesized using cationic and non-ionic structure-directing agents (cetyltrimethylammonium bromide, Pluronic F127 and P123) while modulating the SiO/CaO content, generating MBG with surface areas of 60-695 m/g.
