Evaluation of strong acid properties of layered HNbMoO6 and catalytic activit…
Abstract. The acid properties and catalytic activity of layered HNbMoO6 for liquid-phase Friedel–Crafts alkylation are examined. 31P MAS NMR spectroscopy using trimethylphosphine oxide as a probe molecule reveals that HNbMoO6 possesses strong acid sites in the interlayer region. Layered HNbMoO6 is demonstrated to display remarkable catalytic performance for this reaction, substantially ex…

Amorphous Carbon Bearing Sulfonic Acid Groups in Mesoporous Silica as a Selec…
Sulfonic acid group (SO3H)-bearing amorphous carbon/mesoporous silica composites were studied for use as solid acid catalysts. Sugar-derived amorphous carbon with SO3H cannot catalyze hydrophobic acid-catalyzed reactions, such as the dimerization of R-methylstyrene, because of the small surface area. However, SO3H-bearing sugar-derived amorphous carbon supported on mesoporous silica exhibits…
