Precipitation Synthesis of CeO2 Nanopowder Pigment

open access: yesJurnal Rekayasa Kimia & Lingkungan, 2023
Nanopowder pigments of CeO2 and CeO2:Fe were synthesized by precipitation method at a moderate calcination temperature of 500oC.  The pigments exhibited pale yellow for CeO2 nanopowder and brick red for CeO2:Fe nanopowder.

Role of CeO2 in Ni/CeO2–Al2O3 catalysts for carbon dioxide reforming of methane

open access: yesApplied Catalysis B: Environmental, 1998
Ni catalysts supported on gamma-Al2O3, CeO2 and CeO2-A1(2)O(3) systems were tested for catalytic CO2 reforming of methane into synthesis gas. Ni/CeO2-Al2O3 catalysts showed much better catalytic performance than either CeO2- or gamma-Al2O3-supported Ni catalysts.

CeO<sub>2</sub>-Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability. [PDF]

open access: yesAdv Sci (Weinh)
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

The In Situ Electrochemical-Chemical Cascade Strategy for Pyruvic Acid Synthesis. [PDF]

open access: yesAdv Sci (Weinh)
By employing an “unsaturation−oxygen coordination engineering” strategy, the local coordination environment is regulated to achieve efficient electrochemical synthesis of H2O2. Importantly, an electrochemical−chemical coupled cascade strategy is utilized for the efficient preparation of pyruvic acid via lactic acid oxidation. ABSTRACT Hydrogen peroxide

Strong Metal-Support Interaction Driven Janus Reconstruction in PtRu Alloys for Low-Temperature Hydrogen Storage. [PDF]

open access: yesAdv Sci (Weinh)
Strong metal‐support interactions (SMSI) drive the spontaneous segregation of RuPt alloy into Janus nanoparticles on CeO2, spatially partitioning Pt‐rich domains for H2 dissociation and Ru‐rich domains for toluene adsorption. This Janus nanocatalysts yield a turnover frequency of 10 906 h−1 for toluene hydrogenation at 50 °C, which is 6.7 times that of
