Abstract:

With environmental benignity and waste reduction in mind, a resilient catalyst based on silica extracted from local rice husk (RHS) after acid digestion and thermal treatment was designed in this work. The mesoporous silica (MS) was produced through textural modification of RHS by cetyltrimethyl-ammonium bromide (CTAB) as a structure-directing agent. The surfaces of RHS xerogel (SG) and CTAB-MS were organically functionalized with mixed amine-terminated silane groups through an easy and swift pathway via condensation. Both nickel and platinum nanoparticles were anchored to the surface of the functionalized silica samples. N2 adsorption, XRD, FTIR, TEM and TGA-DSC techniques were used for characterizing the as-functionalized catalytic systems. The metal anchored-functionalized silica catalysts were applied in ethanol dehydrogenation at different temperatures for selective production of acetaldehyde, using a fixed-bed flow reactor. Nanonickel-functionalized silica xerogel (F-SG-Ni) exhibited the highest selectivity toward acetaldehyde production
