Title: XAFS Study of the Photo-Active Site of Mo/MCM-41

Abstract

An Mo/MCM-41 catalyst was prepared and used for study of propene and 1-butene photo-metathesis reactions. XAFS analysis revealed that hydrogen reduction leads to a decreased role for the Mo=O site. The Mo-O site plays an important role for the olefin photo-metathesis reaction on the H2 reduced Mo/MCM-41. From EXAFS analysis, the active site of photo-metathesis reaction is the Mo=O part for oxidized Mo/MCM-41, whereas it is the Mo-O site for reduced Mo/MCM-41.

  • The activity of the photo-assisted selective catalytic reduction of NO with NH3 (photo-SCR) was enhanced by the addition of WO3 to TiO2. From the result of XAFS analysis, the W species on TiO2 had a WO4 tetrahedral structure and agglutination took place as the addition of WO3 was increased. We conclude that the isolated W species enhances the surface acidity and photo-SCR activity whereas the agglutinated W species is an inactive species.
  • Cobalt metal is a good catalyst for CO disproportionation to single-walled carbon nanotubes (SWNT) when particle size is stabilized on the nanometer scale. With reaction temperatures in the range of 973-1123 K, stabilization of nanometer Co particles against sintering requires a chemical bonding and/or occlusion of the Co particles. Catalysts with Co-grafted Mo-incorporated MCM-41 with different Mo loadings (<1 wt %) have been synthesized. Incorporation of Mo cations in the silica framework of MCM-41 provides different species as grafting sites. These grafting sites affect the strength of the metal-support interaction that controls sintering of active Co metal. The stability ofmore » Co at high temperature has been investigated by TPR and in situ/ex-situ X-ray absorption spectroscopy. The reduced Co metal particle size, after hydrogen prereduction, is independent of Mo loading. However, the Co particle size after SWNT synthesis is greatly affected by Mo anchoring and varied with loading. The Co particle size of low-Mo-loading samples after SWNT synthesis is little changed (from 0.88 nm after prereduction to 0.85 nm after SWNT synthesis), but the Co particle size difference of high-Mo-loading samples is gradually increased as the Mo loading is increased.« less
  • The formation process of the MCM-41 precursors (silicate/surfactant complex) was investigated on the basis of the pH titration curves of Na{sub 4}SiO{sub 4} in the presence of [C{sub 16}H{sub 33}N(CH{sub 3}){sub 3}]Cl. Measurements of the pH titration curves were carried out using the computer-controlled gravimetric titrator constructed in their laboratory. The white precipitate (MCM-41 precursor) was abruptly formed at pH 11.1 (298 K) and at pH 9.9 (343 K). Formation of the MCM-41 precursor can be explained by coagulation of the rod-like micelle colloids whose surface is covered by the condensed silicate anions of (HSiO{sub 3}){sub n}{sup n{minus}}. The porousmore » texture of the MCM-41 samples whose precursors were synthesized under different conditions was analyzed on the basis of the adsorption isotherms of nitrogen at 77 K. It has been shown that the MCM-41 sample whose precursor was prepared at pH 9.9 and 343 K shows one sharp peak (r{sub p} = 1.65 nm) in the pore size distribution curve, but the MCM-41 samples whose precursors were prepared at pH 6.5--5.0 and 343 K give two peaks (r{sub p} = 1.66 nm and r{sub p} = 2.12--2.36 nm). The appearance of the second peak (r{sub p} = 2.12--2.36 nm) has been considered to be in connection with the destruction of the MCM-41 precursor into small fragments in acidic medium.« less
  • For the first time, modifications of the surface and framework of Si-MCM-41 by depositing a heteropolyacid on the surface and by introducing foreign Zr{sup 4+} ions into the framework are investigated. The Zr-modified Si-MCM-41 mesoporous materials (hereafter referred as WSZn, n=Si/Zr=25, 15, 8, 4) were synthesized through a surfactant-templated preparation approach, using low-cost fumed silica as the Si precursor. After impregnation with 25 wt% of H{sub 3}PW{sub 12}O{sub 40}, the surface Broensted acidity of the Pt/H{sub 3}PW{sub 12}O{sub 40}/WSZn catalysts was greatly enhanced by 2-10 times relative to the bare WSZn support. Two kinds of supported heteropolyacids were formed: (i)more » bulk-like heteropolyacid crystals with unchanged Keggin structures, and (ii) highly dispersed heteropolyacid with distorted Keggin units. The formation of various kinds of heteropolyacid structures is closely related to the interaction between the heteropolyanions and the hydroxyl groups in the host support. - Graphical abstract: Modifications of the surface and framework of Si-MCM-41 by depositing a heteropolyacid on the surface and by introducing foreign Zr{sup 4+} ions into the framework are investigated.

  • Rh-exchanged Al-MCM-41 is studied for selective catalytic reduction (SCR) of NO by C{sub 3}H{sub 6} in the presence of excess oxygen. It shows a high activity in converting NO to N{sub 2} and N{sub 2}O at low temperatures. In situ FT-IR studies indicate that Rh-NO{sup +} species (1910--1898 cm{sup {minus}1}) is formed on the Rh-Al-MCM-41 catalyst in flowing NO/He, NO + O{sub 2}/He and NO + C{sub 3}H{sub 6} + O{sub 2}/He at 100--350 C. This species is quite active in reacting with propylene and/or propylene adspecies (e.g., {pi}-C{sub 3}H{sub 5}, polyene, etc.) at 250 C in the presence/absence ofmore » oxygen, leading to the formation of the isocyanate species (Rh-NCO, at 2174 cm{sup {minus}1}), CO, and CO{sub 2}. Rh-NCO is also detected under reaction conditions. A possible reaction pathway for reduction of NO by C{sub 3}H{sub 6} is proposed. In the SCR reaction, Rh-NO{sup +} and propylene adspecies react to generate the Rh-NCO species, then Rh-NCO reacts with O{sub 2}, NO, and NO{sub 2} to produce N{sub 2}, N{sub 2}O, and CO{sub 2}. Rh-NO{sup +} and Rh-NCO species are two main intermediates for the SCR reaction on Rh-Al-MCM-41 catalyst.« less
