Curcumin loaded mesoporous silica nanoparticle (SBA-15) was incorporated into chitosan (CS) film to improve the functional properties of pure CS film. Curcumin was loaded into SBA-15 (SBA-15-Cur) through a rotavapor method. The structural properties of SBA-15-Cur were characterised in detail by small-angle X-ray scattering, fourier transform-infrared (FT-IR) spectroscopy, transmission electron…

Alumina materials have widely been used in industrial fields, such as catalysis and adsorption. However, due to the fast sol–gel process and complicated crystalline-phase transformation, the synthesis of alumina materials with both highly ordered mesostructures and crystallized frameworks remains a great challenge. Herein, we report a novel vesicle-aggregation-assembly strategy to…

Epsilon-Fe2O3 Nanocrystals inside Mesoporous Silicas with Tailored Morphologies of Rod, Platelet and Donut

Li, Jheng-Guang; Fornasieri, Giulia; Bleuzen, Anne; Gich, Martí; Impéror‐Clerc, Marianne

The ϵ-Fe2O3 polymorph of iron oxide, which has outstanding physical properties, is successfully stabilized inside mesoporous silica particles with tailored shapes. Using mesoporous silica particles with three different morphologies of rod, platelet and donut, we obtain ϵ-Fe2O3/mesoporous silica nanocomposites. Iron oxide is loaded inside the porosity using a two steps…

Acid Induced Self-Assembly Strategy to Synthesize Ordered Mesoporous Carbons from Biomass

Xu, Fan; Chen, Yiqing; Tang, Minghui; Wang, Haiyan; Deng, Jiang; Wang, Yong

Hydrothermal carbonization of biomass is an economic and sustainable technique for the fabrication of functional carbonaceous materials. However, the introduction of biomass into synthesis of ordered mesoporous carbon materials achieves slow progress due to complicated requirements. It is still challenging to prepare biomass-derived ordered mesoporous carbon materials. Herein, we report…
