Thermally Stable and Regenerable Platinum-Tin Clusters for Propane Dehydrogenation Prepared by Atom Trapping on Ceria
Haifeng Xiong,Sen Lin,Joris Goetze,Paul Pletcher,Hua Guo,Libor Kovarik,Kateryna Artyushkova,Bert M. Weckhuysen,Abhaya K. Datye +8 more
TL;DR: Ceria (CeO2) supports are unique in their ability to trap ionic platinum (Pt), providing exceptional stability for isolated single atoms of Pt, and upon oxidation the Pt–Sn clusters readily revert to the atomically dispersed species on CeO2, making Pt– Sn/Ce O2 a fully regenerable catalyst.
Journal ArticleDOI
Structure–performance descriptors and the role of Lewis acidity in the methanol-to-propylene process
Irina Yarulina,Irina Yarulina,Kristof De Wispelaere,Simon Bailleul,Joris Goetze,Mike Radersma,Edy Abou-Hamad,Ina Vollmer,Maarten G. Goesten,Brahim Mezari,Emiel J. M. Hensen,Juan S. Martinez-Espin,Magnus Mortén,Sharon Mitchell,Javier Pérez-Ramírez,Unni Olsbye,Bert M. Weckhuysen,Veronique Van Speybroeck,Freek Kapteijn,Jorge Gascon,Jorge Gascon +20 more
TL;DR: It has been shown that introducing Lewis acidity into Brønsted acidic zeolites boosts their performance, and although BrøNsted acidity is found to define propylene selectivity, Lewis acidality is responsible for prolonging lifetime.
Journal ArticleDOI
Insights into the Activity and Deactivation of the Methanol-to-Olefins Process over Different Small-Pore Zeolites As Studied with Operando UV–vis Spectroscopy
Joris Goetze,Florian Meirer,Irina Yarulina,Jorge Gascon,Freek Kapteijn,Javier Ruiz-Martínez,Bert M. Weckhuysen +6 more
TL;DR: It was found that small differences in cage size, shape, and pore structure of the zeolite frameworks result in the generation of different hydrocarbon pool species.
Journal ArticleDOI
In Situ Luminescence Thermometry To Locally Measure Temperature Gradients during Catalytic Reactions.
Robin G. Geitenbeek,Anne-Eva Nieuwelink,Thimo S. Jacobs,Bastiaan B. V. Salzmann,Joris Goetze,Andries Meijerink,Bert M. Weckhuysen +6 more
TL;DR: Bandshape luminescent thermometry during in situ temperature measurements has been reported by preparing three catalytically relevant systems, which show temperature-dependent luminescence, which was further investigated as a showcase for application.
Journal ArticleDOI
Spatiotemporal coke formation over zeolite ZSM-5 during the methanol-to-olefins process as studied with: Operando UV-vis spectroscopy: A comparison between H-ZSM-5 and Mg-ZSM-5
Joris Goetze,Bert M. Weckhuysen +1 more
TL;DR: In this paper, the formation of hydrocarbon pool species as well as the accumulation of coke and coke precursor molecules were monitored with operando UV-vis spectroscopy using three probes at different positions along the reactor bed simultaneously.
