Abstract Efficiently treating methane emissions in transportation remains a challenge. Here, we investigate palladium and platinum mono- bimetallic ceria-supported catalysts synthesized by mechanical milling traditional impregnation for total oxidation under dry wet conditions, reproducing those present the exhaust of natural gas vehicles. By applying toolkit situ synchrotron techniques (X-ray diffraction, X-ray absorption ambient pressure photoelectron spectroscopies), together with...
Abstract We report a very efficient homogeneous system for the visible‐light‐driven hydrogen production in pure aqueous solution at room temperature. This comprises [Rh III (dmbpy) 2 Cl ]Cl ( 1 ) as catalyst, [Ru(bpy) 3 PS1 photosensitizer, and ascorbate sacrificial electron donor. Comparative studies solutions also performed with other known rhodium catalysts, or an iridium show that 1) / /ascorbate/ascorbic acid is by far most active rhodium‐based photocatalytic purely medium when compared...
Ni-Fe nanocatalysts supported on CeO2 have been prepared for the catalysis of methane steam reforming (MSR) aiming coke-resistant noble metal-free catalysts. The catalysts synthesized by traditional incipient wetness impregnation as well dry ball milling, a green and more sustainable preparation method. impact synthesis method catalytic performance catalysts' nanostructure has investigated. influence Fe addition addressed well. reducibility electronic crystalline structure Ni mono-...
A mechanochemical synthesis method has been used to synthesize CoRu nanoparticles supported on CeO2 for methane dry reforming. In this work, we study the effect of Ru addition Co/CeO2-based catalysts and by screening their catalytic activity, using synchrotron X-ray diffraction (XRD), operando near-ambient pressure photoelectron spectroscopy (NAP-XPS). Ruthenium directly impacts reducibility cobalt species results in smaller particle sizes, as demonstrated H2-temperature programmed reduction...

A stable Pd 0 /Pd 2+ arrangement generated on Pd/CeO 2 prepared by mechanochemistry enables high methane activation rates in the absence of excess oxygen being available.
Supported Pd/CeO2 catalytic systems have been widely investigated in the low-temperature oxidation of CO (LTO CO) due to unique oxygen storage capacity and redox properties ceria support, which highly influence structural, chemical electronic state Pd species. Herein, operando near-ambient pressure XPS (NAP-XPS) technique has allowed study a conventional catalyst surface during reaction under experimental conditions closer actual reaction, unfeasible with other science techniques that demand...
