Biotechnological fabrication of LaMnO3-carbon catalyst for n-butanol conversion to ketones

摘要: Abstract An attempt to synthesize a hybrid carbon-based material for catalytic purposes was made using biotechnological approach. The consists of carbon matrix in which LaMnO3 nanocrystallites are dispersed. perovskite-type oxide crystallites were synthesized the by transformation lanthanum and manganese salts, penetrated living tissues plant due natural transport metal ions. Cellulose/lignin rich stems carbonized at 600–800 °C 1–22 h, yielding microporous complex uniformly distributed. (Salix viminalis) selected because its high tolerance heavy formation from organic precursor is key factor synthesis inorganic dispersion. materials tested as catalysts unconventional conversion n-butanol heptanone-4. exhibited selectivity product yield, despite extremely low content (0.3% atomic). paper proves that catalysis-oriented functionalization carbons may begin very early stage through chemical modification.
