Study of Hydrogen Adsorption on Pt/WO_3-ZrO_2 through Pt Sites

引用

Journal of Natural Gas Chemistry 2007年第3期16卷 252-257页

作者： Sugeng Triwahyono Aishah abdul jalil Hideshi Hattori Ibnu Sina Institute for Fundamental Science Studies Faculty of SciencesUniversiti Teknologi Malaysia81310 UTM SkudaiJohorMalaysia Faculty of Chemical & Natural Resources Engineering Universiti Teknologi Malaysia81310 UTM SkudaiJohorMalaysia Center for Advanced Research of Energy Technology Hokkaido UniversityNishi 5Kita 8Sapporo060-0808Japan

The rate determining step and the energy barrier involved in hydrogen adsorption on Pt/WO3- ZrO2 were studied based on the assumption that the hydrogen adsorption occurs only through Pt sites. The rate of hydrogen adsorption on Pt/WOa-ZrO2 was measured in the adsorption temperature range of 323-573 K and an initial hydrogen pressure of 50 Torr. The rates of hydrogen uptake were very high for the initial few minutes and the adsorption continued for more than 5 h below 523 K. The hydrogen uptake far exceeded the H/Pt ratio of unity for all adsorption temperatures, indicating that the adsorption of hydrogen involved the dissociative adsorption of hydrogen on Pt sites to form hydrogen atoms, the spillover of hydrogen atoms onto the surface of the WO3-ZrO2 catalyst, the diffusion of spiltover hydrogen atom over the surface of the WO3-ZrO2 catalyst, and the formation of protonic acid site originated from hydrogen atom by releasing an electron in which the electron may react with a second hydrogen atom to form a hydride near the Lewis acid site. The rate determining step was the spillover with the activation energy of 12.3 kJ/mol. The rate of hydrogen adsorption cannot be expressed by the rate equation based on the assumption that the rate determining step is the surface diffusion. The activity of Pt/WO3-ZrO2 was examined on n-heptane isomerization in which the increase of hydrogen partial pressure provided positive-effect on the conversion of n-heptane and negative-effect on the selectivity towards iso-heptane.

The Effect of Sulfate Ion on the Isomerization of n-Butane to iso-Butane

引用

Journal of Natural Gas Chemistry 2006年第4期15卷 247-252页

作者： Sugeng Triwahyono Zalizawati abdullah Aishah abdul jalil Ibnu Sina Institute for Fundamental Science Studies Faculty of Chemical and Natural Resources Engineering Universiti Teknologi Malaysia 81310 SkudaiJohorMalaysia

The effect of sulfate ion （SO4^2-） loading on the properties of Pt/SO4^2-ZrO2 and on the catalytic isomerization of n-butane to/so-butane was studied. The catalyst was prepared by impregnation of Zr（OH）4 with H2SO4 and platinum solution followed by calcination at 600 ℃. Ammonia TPD and FT-IR were used to confirm the distribution of acid sites and the structure of the sulfate species. Nitrogen physisorption and X-ray diffraction were used to confirm the physical structures of Pt/SO4^2-ZrO2. XRD pattern showed that the presence of sulfate ion stabilized the metastable tetragonal phase of zirconia and hindered the transition of amorphous phase to monoclinic phase of zirconia. Ammonia TPD profiles indicated the distributions of weak and medium acid sites observed on 0.1 N and 1.0 N sulfate in the loaded catalysts. The addition of 2.0 N and 4.0 N sulfate ion generated strong acid site and decreased the weak and medium acid sites. However, the XRD results and the specific surface area of the catalysts indicated that the excessive amount of sulfate ion collapsed the structure of the catalyst. The catalysts showed high activity and stability for isomerization of n-butane to iso-butane at 200 ℃ under hydrogen atmosphere. The conversion of n-butane to iso-butane per specific surface area of the catalyst increased with the increasing amount of sulfate ion owing to the existence of the bidentate sulfate and/or polynucleic sulfate species （（ZrO）2SO2）, which acts as an active site for the isomerization.

Recent Development of Sustainable Ecological Flame Retardant Textile Composite Material: A Review

Journal of Materials Science and Chemical Engineering 2022年第6期10卷 30-44页

The ecological and sustainable product is the demand of the present world. But it was not possible to produce an ecological and sustainable product for all sectors as the world requires now. The synthetic material is used to produce flame retardant materials due to the unavailable sustainable ecological flame-retardant material. But different researchers are trying to produce sustainable ecological flame-retardant material. This research found that the Spinach leaves Juice, banana pseudostem sap (SAP) and eggshell powder have flame retardant properties. Different literature shows that the ash also has flame retardant properties. So researcher suggested developing the composite material from the above materials with cotton fibres. It may be more effective as fire-retardant composite materials.
