Journal ArticleDOI
Synthesis of 12-tungestophosphoric acid supported on Zr/MCM-41 composite with excellent heterogeneous catalyst and promising adsorbent of methylene blue
Amr Awad Ibrahim,Reda S. Salama,S.A. El-Hakam,Abdelrahman S. Khder,Abdelrahman S. Khder,Awad I. Ahmed +5 more
TL;DR: In this article, a mesoporous MCM-41 composite was synthesized through the surfactant-assisted sol-gel technique, and different weight percentages of phosphotungstic acid (PTA) were loaded over Zr-MCM41 composites by wet impregnation method.
Journal ArticleDOI
Synthesis of sulfated zirconium supported MCM-41 composite with high-rate adsorption of methylene blue and excellent heterogeneous catalyst
TL;DR: In this paper, Zirconia-based mesoporous MCM-41 was successfully prepared then loaded with different content of sulfate (5, 10, 15, 25, 40 and 50 wt%) through the wet impregnation method.
Journal ArticleDOI
Highly efficient, recyclable cerium-phosphate solid acid catalysts for the synthesis of tetrahydrocarbazole derivatives by Borsche–Drechsel cyclization
Hatem M. Altass,Abdelrahman S. Khder,Abdelrahman S. Khder,Saleh A. Ahmed,Saleh A. Ahmed,Moataz Morad,Abdullah A. Alsabei,Rabab S. Jassas,Khalid Althagafy,Awad I. Ahmed,Reda S. Salama +10 more
TL;DR: In this paper, a series of cerium phosphate catalysts with different cerium to phosphate molar ratios have been synthesized by means of FTIR, DTA, TGA, XRD, N2 adsorption-desorption and SEM.
Journal ArticleDOI
CO oxidation over nobel metals supported on copper oxide: effect of Cu+/Cu2+ ratio
Abdelrahman S. Khder,Abdelrahman S. Khder,Saleh A. Ahmed,Saleh A. Ahmed,Hatem M. Altass,Moataz Morad,Amr Awad Ibrahim +6 more
TL;DR: In this paper, a variety of physicochemical characterization tools were applied to study the catalysts and the results confirmed the formation of a mixture of Cu+/Cu2+ species after Au or Pd nanoparticles deposition, with a higher ratio of Pd rather than Au nanoparticles.
Journal ArticleDOI
Unprecedented green chemistry approach: tungstophosphoric acid encapsulated in MOF 199 as competent acid catalyst for some significant organic transformations
Abdelrahman S. Khder,Abdelrahman S. Khder,Moataz Morad,Hatem M. Altass,Amr Awad Ibrahim,Saleh A. Ahmed,Saleh A. Ahmed +6 more
TL;DR: In this article, a series of 12-tungstophosphoric acid (HPW) encapsulated MOF 199 catalysts were synthesized by simple and convenient one-step method.
