Dehydration of xylose over sulfated tin oxide catalyst: Influences of the preparation conditions on the structural properties and catalytic performance
TL;DR: In this article, various sulfated metal oxides were tested as solid acid catalyst for the dehydration of xylose to furfural under milder conditions, and the acid property on the sulfated tin oxide catalyst was characterized by in situ FT-IR observations of the CO-adsorbed sample.
Synthesis and catalytic properties of a new titanosilicate molecular sieve with the structure analogous to MWW-type lamellar precursor
TL;DR: In this article, a new titanosilicate molecular sieve structurally analogous to MWW-type lamellar precursors (designated as Ti-YNU-1) was postsynthesized by adjusting the titanium content in the synthesis gel and washing the as-synthesized material with acid under refluxing conditions.
Pure silica NU-1 and Na- and Al-free Ti-NU-1 synthesized by the dry gel conversion method
Asim Bhaumik,Takashi Tatsumi +1 more
TL;DR: In this paper, the authors synthesize pure silica NU-1 and its titanium silicate analog Ti-NU1, free from Na and Al, using the dry gel conversion technique, which was not previously possible under the conventional hydrothermal synthesis procedure.
Photocatalytic decomposition of NO at 275 K on titanium oxide catalysts anchored within zeolite cavities and framework
Hiromi Yamashita,Yuichi Ichihashi,Shu Guo Zhang,Yasuyuki Matsumura,Yoshie Souma,Takashi Tatsumi,Masakazu Anpo +6 more
TL;DR: In this paper, the in situ photoluminescence and XAFS investigations indicate that these titanium oxide species are highly dispersed and exist in a tetrahedral coordination in the zeolite cavities and its framework.
Adsorption of Chromate and Arsenate by Amino-Functionalized MCM-41 and SBA-1
TL;DR: In this paper, the authors report the characteristics of aminosilane-grafted mesoporous silicas as adsorbents of oxyanions in acidic conditions and examine the influence of amino group density.
