Au@CeO2 nanoparticles supported Pt/C electrocatalyst to improve the removal of CO in methanol oxidation reaction

Bismuth Oxyhydroxide-Pt Inverse Interface for Enhanced Methanol Electrooxidation Performance

“…To enhance the antipoisoning ability of Pt-based catalysts, one strategy is via alloying Pt with other metals, such as Ru, , Cu, , Ni, − and Co, to tune the electronic structure of Pt, which thus weakens CO adsorption. In addition to the alloy system, some metal oxides , and hydroxides/oxyhydroxides have been used to support Pt as they can facilitate the generation of abundant OH species for oxidative removal of adsorbed CO. Notably, the interface between Pt and the support plays a crucial role in improving the catalytic performance since it provides the channel for charge redistribution and vicinity for intermediate spillover.…”

CeO2 decorated bimetallic phosphide nanowire arrays for enhanced oxygen evolution reaction electrocatalysis via interface engineering

“…38,39 Moreover, owing to the mechanical stability and the excellent anti-corrosion ability, CeO 2 could inhibit the degradation of the host electrocatalysts. [40][41][42] Inspired by the abovementioned considerations, it would be attractive to fabricate TMP based heterostructure coupled with CeO 2 to enhance the OER performance, which however, has not been reported. Herein, we reported a novel heterostructure Co 0.4 Ni 43 First, commercial NF was treated by sequential ultrasonic baths in 3 M HCl, ethanol, and DI water.…”

Rare Self-Luminous Mixed-Valence Eu-MOF with a Self-Enhanced Characteristic as a Near-Infrared Fluorescent ECL Probe for Nondestructive Immunodetection

“…The efficiency of charge utilization is conclusive for the whole performance of catalysis. A good catalytic activity can be realized effectually via an ideal platform offered by the core–shell structure, which has sufficient diffusion channels and a large active specific surface area to possess high conductivity and resistance to reunite. , Among these core–shell structure materials, the CeO 2 microsphere has gained massive attention with merits of its ultrahigh electrocatalytic activity resulted from the inherent Ce 3+ /Ce 4+ redox pair and remarkable durability in water. , Surprisingly, the catalytic performance will be further promoted through the synergistic effect between CeO 2 and metal oxides (e.g., TiO 2 , Co 3 O 4 , Fe 2 O 3 , and NiO) . The change in the valence of Ce 3+ /Ce 4+ and Co 2+ /Co 3+ can promote more production of coreactant radicals; therefore, the combination of Co 3 O 4 and CeO 2 has high-efficiency catalytic capacity to improve the ECL intensity. , …”
