TAILIEUCHUNG - Starch functionalization of trimetallic W-Mg-Al oxide for oxidative desulphurisation of dibenzothiophene

A novel trimetallic W-Mg-Al oxide composites immobilised onto starch were synthesized via sol-gel method. W-Mg-Al oxide composites were synthesized by first preparing WO3 using incipient wetness method, followed by immobilising onto MgO-Al2O3 support using starch as binder. | Starch functionalization of trimetallic W-Mg-Al oxide for oxidative desulphurisation of dibenzothiophene Current Chemistry Letters 9 2020 143 150 Contents lists available at GrowingScience Current Chemistry Letters homepage Starch functionalization of trimetallic W-Mg-Al oxide for oxidative desulphurisation of dibenzothiophene Melody Kimia Zainab Ngainib and Sinin Hamdanc a Centre for Pre-University Studies Universiti Malaysia Sarawak 94300 Kota Samarahan Sarawak Malaysia b Department of Chemistry Faculty of Science and Resource Technology Universiti Malaysia Sarawak 94300 Kota Samarahan Sarawak Malaysia c Department of Mechanical Engineering Faculty of Engineering Universiti Malaysia Sarawak 94300 Kota Samarahan Sarawak Malaysia CHRONICLE ABSTRACT Article history A novel trimetallic W-Mg-Al oxide composites immobilised onto starch were synthesized via Received October 30 2019 sol-gel method. W-Mg-Al oxide composites were synthesized by first preparing WO3 using Received in revised form incipient wetness method followed by immobilising onto MgO-Al2O3 support using starch as November 21 2019 binder. The effects of starch addition on the crystal properties and morphology were Accepted January 10 2020 investigated by X-ray diffraction XRD Fourier Transform Infrared FT-IR spectroscopy Available online and Scanning Electron Microscopy SEM . In the presence of hydrogen peroxide and acetic January 10 2019 acid as oxidant system W-Mg-Al oxide starch composites exhibited higher catalytic Keywords performances for oxidative desulphurisation ODS of dibenzothiophene DBT at 95 Oxidative desulphurization compared to W-Mg-Al oxide composites. The catalytic activity observed could be correlated Dibenzothiophene to the distribution of active phases on starch as well as the higher crystallinity of the metal Trimetallic oxide oxide composites.
