Abstract Tantalum nitride (Ta3N5) has emerged as a promising photoanode material for photoelectrochemical (PEC) water splitting. However, the inefficient electron-hole separation remains a bottleneck that impedes its solar-to-hydrogen conversion efficiency.

Graphical Abstract Highly efficient electron/hole separation and collection has been achieved by in situ interface bonding of an ultrathin high-crystallinity Ta3N5 mono-grain shell and conductive NbNx nanorod core. The photoanode attains a photocurrent density of 7 mA cm−2 at 1.23 V RHE with a Ta3N5 shell thickness of less than 30 nm. Abstract Tantalum nitride (Ta3N5) has emerged as a promising photoanode material for photoelectrochemical (PEC) water splitting.

Abstract Large-bandwidth x-ray free-electron-laser (XFEL) facilities are desirable scientific tools in various fields, such as molecular structural dynamics and spectroscopy diagnosis. Various methods are proposed to broaden the FEL spectra. Here, a method is proposed to generate high-power XFEL radiation of tunable spectral bandwidth using plasma wakefield acceleration.
