Growth and Functionalization of Particle-Based Mesoporous Silica Films and Their Usage in Catalysis.

摘要: We report the formation of mesoporous films consisting SBA-15 particles grown directly onto substrates and their usage as catalysts in esterification acetic acid ethanol. The film thickness was altered between 80 nm 750 by adding NH₄F to synthesis solution. salt also affects rate particles, must be added during siliceous network Various substrate functionalizations were tested hydrophobic are required for a successful growth. show that large surfaces (> 75 cm²), well 3D substrates, can homogenously coated. Further, functionalized, either with through co-condensation, or coating thin carbon layer exposure furfuryl alcohol fumes followed carbonization sulfonation H₂SO₄. carbon-coated shown an efficient catalyst reaction Due short, accessible mesopores, chemical variability, possibility cover large, rough surfaces. have potential various applications such catalysis, sensing, drug delivery.
