Despite the intriguing potential, nano‐socketed Cu/perovskite heterostructures for CO2 electroreduction (CO2RR) are still in their infancy and rational optimization of their CO2RR properties is lacking. Here, an effective strategy is reported to promote CO2‐to‐C2+ conversion over nano‐socketed Cu/perovskite heterostructures by A‐site‐valence‐controlled oxygen vacancies. For the proof‐of‐concept catalysts...
Developing robust and highly active bifunctional electrocatalysts for overall water splitting is critical for efficient sustainable energy conversion. Herein, heteroatom‐doped amorphous/crystalline ruthenium oxide‐based hollow nanocages (M‐ZnRuOx (MCo, Ni, Fe)) through delicate control of composition and structure is reported. Among as‐synthesized M‐ZnRuOx nanocages, Co‐ZnRuOx nanocages deliver an...
Maximized specific loss power and intrinsic loss power approaching theoretical limits for alternating‐current (AC) magnetic‐field heating of nanoparticles are reported. This is achieved by engineering the effective magnetic anisotropy barrier of nanoparticles via alloying of hard and soft ferrites. 22 nm Co0.03Mn0.28Fe2.7O4/SiO2 nanoparticles reach a specific loss power value of 3417 W g−1metal at...
In article number 1800135, Hao Zeng and co‐workers design and develop biocompatible magnetic nanoparticles with maximized specific and intrinsic loss power, by alloying hard and soft ferrites to engineer their effective anisotropy. The very high intrinsic loss power enables a dilute solution of nanoparticles to be heated above the hyperthermia temperature within minutes at an ultralow AC magnetic...
