Multi‐component composite materials with a magnetic‐dielectric synergistic effect exhibit satisfactory electromagnetic wave absorption performance. However, the effective construction of the structure for these multi‐component materials to fully exploit the advantages of each component remains a challenge. Inspired by natural biomass, this study utilizes wood as the raw material and successfully prepares...
Fabrication of transition‐metal catalytic materials is regarded as a promising strategy for developing high‐performance sodium–selenium (Na–Se) batteries. However, more systematic explorations are further demanded to find out how their bonding interactions and electronic structures can affect the Na storage process. This study finds that lattice‐distorted nickel (Ni) structure can form different bonding...
Tungsten oxide (WO3) is an appealing electrocatalyst for the hydrogen evolution reaction (HER) owing to its cost‐effectiveness and structural adjustability. However, the WO3 electrocatalyst displays undesirable intrinsic activity for the HER, which originates from the strong hydrogen adsorption energy. Herein, for effective defect engineering, a hydrogen atom inserted into the interstitial lattice...
