Pt-loaded Au@CeO₂ core–shell nanocatalysts for improving methanol oxidation reaction activity

Abstract

Ultralow Pt-loaded Au@CeO2 core–shell nanocatalysts have been successfully prepared for methanol oxidation reaction activity for the first time.

A Review on Ceo2‐Based Electrocatalyst and Photocatalyst in Energy Conversion

“…[ 93 ] Dao et al constructed Au@CeO 2 core–shell supported Pt catalyst for MOR (Figure 4g–i). [ 94 ] The catalyst showed not only a good catalytic activity but also high CO tolerance because that Au@CeO2 core–shell structure promotes the oxidation of CO (Figure 4j). In addition to modifying the support, alloying Pt with another transition metal is another efficient method to improve the catalytic performance for M/EOR.…”

Engineering well-defined rare earth oxide-based nanostructures for catalyzing C1 chemical reactions

“…Although it is difficult for rare earth oxide nanomaterials to be used as a single catalyst in MOR, there are many cases that combine rare earth oxide nanomaterials with other well-conducting catalysts for the MOR. [126][127][128][129][130][131][132][133] This not only can enhance the electronic metal support interactions, but also tune the chemical adsorption of the reactants and intermediates. As an example, Li et al 126 studied the introduction of Y 2 O 3 on the MOR activity of the Pd/C catalyst.…”

“…Furthermore, the authors loaded Pd-La 2 O 3 on chitosan-functionalized carbon nanotubes and obtained a better performance than that with Pd-La 2 O 3 /C. In addition, a 3D core-shell nanocatalyst of Au@CeO 2 @Pt/C for the MOR was obtained by Dao et al 130 through a facile hydrothermal route. The as-prepared catalyst showed much higher activity (MA = 1360 mA mg Pt −1 ) and durability than that of commercial Pt/C (MA = 670 mA mg Pt −1 ) and CeO 2 @Pt/C (MA = 920 mA mg Pt −1 ) owing to the electronic and synergistic effects among Au, CeO 2 and Pt, which could easily remove the poisoner of CO intermediates (Fig.…”

LaFeO3 meets nitrogen-doped graphene functionalized with ultralow Pt loading in an impactful Z-scheme platform for photocatalytic hydrogen evolution

“…1 Hence, it has huge potential to address several pressing issues of sustainability and global warming. 2 However, the development of cost-effective and green methods to produce hydrogen fuel remains a big challenge. In this regard, the photocatalytic hydrogen evolution (PHE) reaction, which directly converts light into hot electron-hole pairs to drive redox catalytic reactions (e.g., water splitting) on semiconductors, 3,4 is a promising approach to produce hydrogen as it offers costeffectiveness, simplicity, and high efficiency.…”
