Non-equilibrium plasma-assisted dry reforming of methane over shape-controlled CeO₂ supported ruthenium catalysts

Abstract

In this report, CeO2 and SiO2 supported 1 wt% Ru catalysts were synthesized and studied for dry reforming of methane (DRM) by introducing non-thermal plasma (NTP) in a dielectric barrier...

Recent advances in the design of high-performance cobalt-based catalysts for dry reforming of methane

“…The application of CeO 2 can enhance the metal–ceria interaction and suppress carbon deposition through the redox cycles of Ce 3+ and Ce 4+ under a reductive atmosphere during the DRM reaction. 184,185 Previous experimental and theoretical studies showed that ceria-supported catalysts had strong metal–support interaction, which greatly improved the catalyst stability. In addition, the redox property of the catalyst is also affected by the morphology of Ce.…”

Synergistic High-Efficiency Photoelectrochemical Water Splitting via Type-II Heterojunction MW:BVO/CeO2 Coupled with Ultrathin NiFeOOH

“…According to reports, integrating energy levels into heterogeneous structures of composite semiconductor photocatalysts can effectively suppress light-induced recombination of charge carriers. − The formation of heterogeneous structures can significantly improve the spatial charge separation effect, prolong the lifetime of charge carriers, and thus greatly enhance the photocatalytic performance . To achieve such a photoanode system, an n-type metal oxide semiconductor is commonly employed due to its ability to perform the anodic OER reaction without semiconductor degradation in highly oxidizing electrochemical environments. , Cerium oxide (CeO 2 ) has been proven to exhibit excellent photocatalytic performance in the degradation of various organic dye pollutants, owing to its high oxygen storage capacity, catalytic reactions involving Ce 3+ /Ce 4+ ion pairs, environmental friendliness, and cost-effectiveness .…”

A highly stable and conductive cerium‐doped Li7P3S11 glass‐ceramic electrolyte for solid‐state lithium–sulfur batteries

“…As a result, they can immobilize and convert polysulfides, thus reducing their migration and alleviating capacity degradation. 45,46,49 When cerium is introduced into Li 2 S-P 2 S 5 (LPS), the defect structure and/or conentration of the material can be modified, thereby enhancing the migration of Li + ions, resulting in an improvement in the ionic conductivity of the material. It is believed that a significant part of this enhancement can be attributed to the introduction of additional mobile charge carriers and the optimization of the Li-ion diffusion pathways.…”

“…The cerium ions (Ce 4+ /Ce 3+ ) can act both as redox mediators and as redox catalysts in Li‐S battery due to their variable oxidation states. As a result, they can immobilize and convert polysulfides, thus reducing their migration and alleviating capacity degradation 45,46,49 . When cerium is introduced into Li 2 S‐P 2 S 5 (LPS), the defect structure and/or conentration of the material can be modified, thereby enhancing the migration of Li + ions, resulting in an improvement in the ionic conductivity of the material.…”

“…6 Carbon dioxide and other pollutants (including greenhouse gases) are reduced in the atmosphere when energy storage devices store energy from renewable sources. 7,8 In this way, global warming and other environmental problems can be mitigated. Currently, lithium-ion battery is undeniably one of the greatest triumphs of modern electrochemistry storage devices due to its high single-cell voltage, lack of memory effect, long cycle life, and high energy density.…”
