High-entropy-alloy nanoparticles (HEA-NPs) show great potential as electrocatalysts for water splitting, fuel cells, CO2 conversion, etc. However, fine-tuning the surface, morphology, structure, and crystal phase of HEA remains a challenge. Here, high-temperature liquid shock (HTLS) technique is applied to produce HEA-NPs, e.g., PtCoNiRuIr with tunable elemental components, ultrafine particle size, controlled phases, lattice strains. HTLS directly Joule heating on mixture metal precursors, capping agents, reducing which feasible controlling morphology structure such atomic arrangement resulting products, thereby facilitating rationally designed nanocatalysts.

Abstract Herein, Co/CoO heterojunction nanoparticles (NPs) rich in oxygen vacancies embedded mesoporous walls of nitrogen‐doped hollow carbon nanoboxes coupled with nanotubes (P–Co/CoO V @NHCNB@NCNT) are well designed through zeolite‐imidazole framework (ZIF‐67) carbonization, chemical vapor deposition, and O 2 plasma treatment. As a result, the three‐dimensional NHCNBs NCNTs unique reduce charge transport resistance accelerate catalytic reaction rate P–Co/CoO @NHCNB@NCNT, they display exceedingly good electrocatalytic performance for reduction (ORR, halfwave potential [ E ORR, 1/2 = 0.855 vs. reversible hydrogen electrode]) evolution (OER, overpotential ( η OER , 10 377 mV@10 mA cm −2 ), which exceeds that commercial Pt/C + RuO most formerly reported electrocatalysts.

Layered oxides are widely accepted to be promising cathode candidate materials for K-ion batteries (KIBs) in terms of their rich raw and low price, while further applications restricted by sluggish kinetics poor structural stability. Here, the high-entropy design concept is introduced into layered KIB cathodes address above issues, an example K0.45Mn0.60Ni0.075Fe0.075Co0.075Ti0.10Cu0.05Mg0.025O2 (HE-KMO) successfully prepared. Benefiting from oxide with multielement doping, developed HE-KMO exhibits half-metallic features a narrow bandgap 0.19 eV. Increased entropy can also reduce surface energy {010} active facets, resulting about 2.6 times more exposure facets than low-entropy K0.45MnO2 (KMO). Both effectively improve electron conduction K+ diffusion. Furthermore, high inhibit space charge ordering during (de)insertion, transition metal–oxygen covalent interaction enhanced, leading suppressed phase 1.5–4.2 V better electrochemical stability (average capacity drop 0.20%, 200 cycles) KMO 0.41%, wide voltage window.
