Abstract Seawater electrolysis is a sustainable technology for producing hydrogen that would neither cause global freshwater shortages nor create carbon emissions. However, this severely hampered by the insufficient stability and competition from chlorine evolution reaction (ClER) in actual application. Herein, metal–organic framework (MOF)‐on‐MOF heterojunction (Ni‐BDC/NH 2 ‐MIL‐88B(Fe)) denoted as (Ni‐BDC/NM88B(Fe)) synthesized an effective oxygen (OER) electrocatalyst high‐performance...
Acidic oxygen evolution reaction (OER) catalysts face the fundamental challenge of trade-off between activity and durability that has not yet been well addressed. Herein, we integrate high nanoparticles good stability bulk materials into a "macro-nano" catalyst through two-dimensional self-assembling unconventional fcc phase Ru3Ir nanocrystals. Such deliver low overpotential 190 mV at 10 mA cm–2 stably maintain this over 400 h or 10,000 potential cycles for acidic OER, surpassing previously...
Metal oxyhydroxides produced by the surface reconstruction were widely considered as active catalytic species in oxygen evolution reaction (OER). However, simultaneous activation of metal sites remains a great challenge. In this study, interface self-activation strategy was utilized to simultaneously activate both iron and nickel at (Fe,Ni)OOH-NiSe2 nano heterostructure. The OER activity greatly boosted dual sites, resulting an overpotential 245 mV@100 mA cm−2 with small Tafel slope 44 mV...
Abstract Rational design of advanced electrocatalysts for oxygen evolution reaction (OER) is vital importance the development sustainable energy. Entropy engineering emerging as a promising approach efficient OER electrocatalysts. However, other multi‐anion/cation with compositional complexity, particularly medium‐entropy and non‐equimolar cation/anion complex electrocatalysts, have not received noteworthy attention. In this perspective, we review highlight compositionally catalysts propose...
Despite the conventional view of liquid aluminum (l-Al) as a simple metal governed by free-electron model, it exhibits unique bonding characteristics. This study uncovers gradual transition from free electron to electride behavior in l-Al at high pressure and temperature, forming type two-component where atomic states coexist. The proportion increases with temperature until reaching saturation, leading notable changes pair-correlation function coordination number saturation pressure....
An acanthosphere-like PtRuRhPdAuIr high-entropy alloy (HEA) was fabricated for the first time by electrochemical method in a deep eutectic solvent. Owing to HEA structure characteristics and synergistic effect...
Exploring earth-abundant electrocatalysts for efficient hydrogen evolution reaction (HER) is important the development of clean and renewable energy.
Transition metal borides are commonly hard and incompressible, offering great opportunities for advanced applications under extreme conditions. Recent studies show that the hardness of high-entropy may exceed their constituent simple due to "cocktail effect". However, how deform elastically remains largely unknown. Here, we two newly synthesized diborides ultra-incompressible, attaining ∼90% incompressibility single-crystalline diamond exhibiting a 50–60% enhancement over density functional...
Purposely changing the rate-determining step (RDS) of oxygen evolution reaction (OER) remains a major challenge for enhancing energy efficiency electrochemical splitting water. Here we show that OER RDS can be regulated by simply varying cation and anion complexity in family metal phosphorous trichalcogenide electrocatalysts (MPT3 , where M=Fe, Ni; T=S, Se), achieving an exceptionally high activity (Ni,Fe)P(S,Se)3 as demonstrated its ultra-low Tafel slope (34 mV dec-1 ) very low...
Here, the ultrafine Pt/Pd bimetallic nanoparticles (Pt/Pd NPs) were synthesized and decorated on multi-walled carbon nanotubes (MWCNTs) modified glassy electrode (GCE) for hydrogen evolution. NPs through reduction of their metal salt mixture with tert-butylamine as reductant polyvinylpyrrolidone protectant. Under observation transmission electron microscopy (TEM), well dispersed exhibit size about 13 nm diameter good crystallinity corresponding to (111) planes face-centered cubic (fcc) Pt...
Cooperative Jahn–Teller (JT) distortion accompanied by electromagnetic lattice coupling plays a crucial role in numerous important phenomena materials science. The JT occurring high-spin 3d4 and 3d9 configurations octahedral complexes is common, but similarly, large due to lifting the degeneracy of t2g orbitals has so far seldomly been observed. Here, we report discovery pressure-induced cooperative effect coupled with volume collapse ∼12.8% magnetic moment from S = 5/2 1/2 at ∼20.9 GPa...
