A selective defect engineering strategy is proposed to deliberately introduce M (II)/M (III) atomic defects into NiFe layered double hydroxides (LDHs). Combining experimental and theoretical findings, it is revealed that dangling Ni-Fe sites efficiently enhance the oxygen evolution reaction (OER); this demonstrates that M (II) defect-containing NiFe LDHs are cost-effective, active, and durable OER electrocatalysts.

The analysis reveals that the oriented growth of 1T-phase MoS2 is controlled by a process involving ammonia-assisted assembly, recrystallization, and stabilization steps. The superior HER performance observed for this system has its origin in its unique array structure with well-dispersed, edge-terminated, and high-purity 1T-phase MoS2 nanosheets.

Atomic movement in a ferroelectric thin film under external electric field and stress was demonstrated for the first time using time-resolved X-ray diffraction. This study indicates that the distance between Fe and O atoms is a key factor determining the polarization in BiFeO3 thin films, rather than the simple displacement of the center atom and/or tetragonality of the unit cell.

We report that the oxygen evolution reaction activity of nickel foam can be enhanced remarkably via only simple immersion in a ferric nitrate solution at room temperature. We demonstrate that the oxidation of the nickel foam surface by nitrate ions can increase the near-surface concentrations of OH and Ni2+ ions, which results in the in situ deposition of a highly active amorphous Ni-Fe hydroxide layer.

The hetero-NWs exhibited abundant catalytic active sites, substantially improved electric conductivity, and significantly enhanced separation of charge carriers, resulting in superior visible-light photocatalytic properties compared with Pt/CdS NWs, pure CdS NWs, and MoS2 NSs, as well as their physical mixtures.
