Formation of the Silicon-Containing Porous Carrier Materials Using Bacterial Cells

Four types of the loading matrices based on triethoxymethylsilane and tetraethoxysilane in the 50/50 vol % ratio were prepared. The matrices were obtained either using Paracoccus yeei bacterial cells VKM B-3302 as templates or without them. The materials were annealed at 600 and 800 °C. The effect of the cells on the resulting loading matrices was analyzed using scanning electron microscopy. It was found that the addition of P.yeei allows for the formation of the more branched surface, which is likely to result in a higher specific surface area.
