Understanding of Oxygen Redox in the Oxygen Evolution Reaction

Xiaopeng Wang et al.

Summary: This article provides a comprehensive review of the oxygen redox process in the oxygen evolution reaction (OER) through lattice oxygen oxidation mechanism (LOM), and discusses the characterization techniques used to identify the oxygen redox. It explains the critical advantage and underlying science of LOM compared to the traditional adsorbate evolution mechanism (AEM) in generating higher OER activities. The article also provides insights into future developments in LOM electrocatalysts.

Improved Water-Gas Shift Performance of Au/NiAl LDHs Nanostructured Catalysts via CeO2 Addition

Margarita Gabrovska et al.

Summary: This study investigated the use of supported gold on co-precipitated nanosized NiAl layered double hydroxides (LDHs) as a catalyst for the medium-temperature water-gas shift (WGS) reaction. By modifying the Au/NiAl catalyst with CeO2, the performance of the catalyst was improved, showing significant effects on CO conversion in the WGS reaction. The innovative synthesis method of directly depositing ceria on NiAl-LDH without calcination treatment offers promising potential for practical applications.
