Spin-engineered Cu–Ni metallic aerogels for enhanced ethylamine electrosynthesis from acetonitrile

Abstract

Spin engineering is an effective strategy to improve the performance of catalysts, but it has been rarely demonstrated for the acetonitrile reduction reaction (ARR) to date.

Lattice‐Strained Metallic Aerogels as Efficient and Anti‐Poisoning Electrocatalysts for Oxygen Reduction Reaction

“…These results show that tensile strain and abundant defects of Pd@PdBiCo MAs would optimize the competitive adsorption between O 2 , CH 3 OH, and CO to enhance ORR activity with anti‐poisoning property. Besides, the special structural advantages of MAs in comparison with nanoparticles that enable them possess higher catalytic activity have been shown in our previous work [26,27] . To further study the anti‐poisoning property of Pd@PdBiCo MAs/C, Pd MAs/C, and the commercial Pd/C, CH 3 OH and CO was added in 0.1 M KOH solution during the chronoamperometry test to observe their current response (Figure 2e–f).…”

In contrast to Pd MAs/C and the commercial Pd/C, the current of Pd@PdBiCo MAs/C hardly changes with the addition of CH 3 OH and CO, showing the inertia of CH 3 OH and CO, which is favorable for the anti-poisoning property.…”

Interface-Engineered Cu/Cu2In Metallic Aerogels for Efficient Electrochemical CO2 Reduction

“…Cu­(NO 3 ) 2 ·3H 2 O was purchased from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China). We have described all other chemicals used in our previous work …”

Engineering the spin configuration of electrocatalysts for electrochemical renewable conversions

“…Meanwhile, through introducing Cu atoms, the distorted crystal structures induced the delocalization of the d-orbit electrons in the whole system, and the original low spin state was adjusted to the delocalized spin state, thus enhancing the overall spin state of the catalysts. 155 Considering that the external field control is beneficial for optimizing the electronic spin state of the alloy catalysts, a CoNi alloy with high saturation magnetization of 89.1 emu g −1 encapsulated in nitrogen-doped carbon material was prepared for highly efficient ORR electrocatalysis. The electronic structure of CoNi@NC was optimized by electron cloud redistribution and spin-state adjustment.…”
