Water-gas shift of reformate streams over mono-metallic PGM catalysts

January 18, 2021

International Journal of Hydrogen Energy Journal

Mono-metallic Pt and Rh catalysts supported on both CeO2 and TiO2 were prepared and tested for water-gas shift activity in a Flowrence, high-throughput reactor system. The feed composition mimicked a typical fuel processor, steam methane reformer outlet stream. The Pt/CeO2 catalyst showed the best metal activity of ∼3.8 E-07 moles CO converted·gPt-1 s-1, at a Pt loading of 0.5 wt%, activity decreasing with increasing metal loading. Furthermore, the Pt/CeO2 catalyst produced almost no methane while the Rh based catalysts led to substantial methanation.

Complementary and Spatially Resolved Operando Spectroscopic Investigation of Pt/Al₂O₃ and Pt/CeO₂ Catalysts during CO/NO Conversion

The composition of reaction mixtures strongly influences the structural evolution and performance of noble metal-based catalysts. In this work, we compared the effect of the simultaneous presence of CO and NO on the noble metal state and CO oxidation activity of Pt/Al2O3 and Pt/CeO2 catalysts under close-to-stoichiometric conditions using complementary in situ/operando X-ray and infrared spectroscopic techniques.

Influence of the CeO₂ Morphology and Initial Pd–Pt Interaction Degree on Catalyst Activity and Stability

Due to its peculiar properties and strong interaction with noble metals, ceria is widely used as a catalyst support for numerous applications. In this work, morphologically pure and highly crystalline ceria nanocubes and nanorods were prepared to systematically investigate both the impact of the support morphology and Pd–Pt interaction degree on the noble metal-support interplay during CO oxidation.

High-throughput RAFT Polymerization via Automated Batch, Increment, and Continuous Flow Platforms

We report an automated strategy to conduct RAFT copolymerizations using a Chemspeed robotic platform capable of executing batch, incremental, and continuous monomer addition workflows under inert conditions. Copolymerizations of oligo(ethylene glycol) acrylate with benzyl acrylate (as a control) and fluorescein o-acrylate were conducted in toluene, THF, and DMF, with reaction progress monitored via ¹H NMR spectroscopy at defined intervals.
