Spectrokinetic investigation of reserve water-gas-shift reaction intermediates over a Pt/CeO2 catalyst
Article Abstract:
The reactivity of the surface species present over a 2%Pt/CeO2 catalyst during the reserve water-gas-shift (RWGS) reaction is investigated by a detailed operando spectrokinetic analysis. The reactivity of the surface species was monitored by DRIFT spectroscopy (DRIFTS) and mass spectrometry (MS) using steady-state isotopic transient kinetic analysis (SSITKA) technique.

Synthesis and characterization of cerium phosphate nanowires in microemulsion reaction media
Article Abstract:
Electron microscopy and dynamic light scattering studies are conducted to explain the production of crystalline nanowires by the synthesis of cerium phosphate [CePo(sub 4)] in microemulsion reaction media. The analysis shows that the crystallization occurs by the strong electrostatic interactions of the negatively charged surfactant with the trivalent Ce(III) ions.

Photoluminescent layered Y(III) and Tb(III) silicates doped with Ce(III)
Article Abstract:
The synthesis and structural characterization of new layered rare-earth silicates K3[[M.1-a][Ce.sub.a]Si3O8(OH)2], M = [Y.sup.3+], [Tb.sup.3+], a << 1, are reported. In mixed Tb/Ce-AV-22, energy transfer occurs from the large [Ce.sup.3+] [4f.sup.1] --> [5d.sup.1] broadband to the sharp [Tb.sup.3+] [4f.sup.8] lines with an efficiency of ca.
