Masakazu Toda,Atsushi Takagaki,Mai Okamura,Junko N. Kondo,Shigenobu Hayashi,Kazunari Domen,Michikazu Hara +6 more
TL;DR: This high-performance catalyst, which consists of stable sulphonated amorphous carbon, is recyclable and its activity markedly exceeds that of other solid acid catalysts tested for ‘biodiesel’ production.
Journal ArticleDOI
A Carbon Material as a Strong Protonic Acid

Journal ArticleDOI
Acid-Catalyzed Reactions on Flexible Polycyclic Aromatic Carbon in Amorphous Carbon
Mai Okamura,Atsushi Takagaki,Masakazu Toda,Junko N. Kondo,Kazunari Domen,Takashi Tatsumi,Michikazu Hara,Shigenobu Hayashi +7 more
TL;DR: In this paper, a functionalized amorphous carbon material with acid catalytic activity as a solid acid replacement for sulfuric acid was used for liquid-phase acid-catalyzed reactions.
Journal ArticleDOI
Hydrotalcite-supported gold-nanoparticle-catalyzed highly efficient base-free aqueous oxidation of 5-hydroxymethylfurfural into 2,5-furandicarboxylic acid under atmospheric oxygen pressure
TL;DR: In this article, a green synthesis of 2,5-furandicarboxylic acid, one of the most important chemical building blocks from biomass, viaoxidation of 5-hydroxymethylfurfural has been demonstrated using hydrotalcite-supported gold nanoparticle catalyst in water at 368 K under atmospheric oxygen pressure without addition of homogeneous base.
Journal ArticleDOI
A one-pot reaction for biorefinery: combination of solid acid and base catalysts for direct production of 5-hydroxymethylfurfural from saccharides
TL;DR: HMF, one of the most important intermediates derived from biomass, was directly produced from monosaccharide and disaccharides by a simple one-pot reaction including hydrolysis, isomerization and dehydration using solid acid and base catalysts under mild conditions.
