Multi-Sites Electrocatalysis in High-Entropy Alloys

TL;DR: In this article , the one-pot synthesis of hexagonal close-packed (hcp) PtRhBiSnSb high-entropy intermetallic (HEI) nanoplates with intrinsically isolated Pt, Rh, Bi, Sn, and Sb atoms is reported, to boost the electrochemical oxidation of liquid fuels.

TL;DR: High-entropy alloys (HEAs) are emerging as powerful electrocatalysts due to their unique active sites and high catalytic activity. Further research is needed to understand the active sites, interactions between constituent elements, and reaction mechanisms of HEAs.

TL;DR: In this paper , a series of high-entropy alloy aerogels (HEAAs) is fabricated via the freeze-thaw method as highly active and durable electrocatalysts for the carbon dioxide reduction reaction (CO2RR), and the PdCuAuAgBiIn HEAAs can achieve Faradaic efficiency (FE) of C1 products almost 100% from −0.7 to −1.1 V versus reversible hydrogen electrode (VRHE), and a maximum FE for formic acid (FEHCOOH).

TL;DR: In this paper , a general strategy for preparing ultralight 3D porous medium-entropy aerogels with the lowest density of 39.3 mg cm−3 among the metal materials is reported, through combining auto-combustion and subsequent low-temperature reduction procedures.

TL;DR: Initial property assessments show that both the hardness and the oxidation resistance of these high-entropy metal diborides are generally higher/better than the average performances of five individual metal dibiaides made by identical fabrication processing.

TL;DR: It is found that the stabilization effect of entropy brings significant benefits for the storage capacity retention of high entropy oxides and greatly improves the cycling stability, and the electrochemical behavior of the high entropy Oxides depends on each of the metal cations present, thus providing the opportunity to tailor the Electrochemical properties by simply changing the elemental composition.

TL;DR: This tutorial review covered the recent progress in the composition and structure optimization of NMEs for OER including Ir- and Ru-based oxides and alloys, and noble-metals beyond Ir and Ru with a variety of morphologies.

TL;DR: In this article, the authors review potential pathways for increasing the cost-effectiveness and efficiency of low-Pt and nonplatinum Pd-Me, Ru-Se and heat-treated MeNxCy based catalysts.
