Abstract Achieving synergistic oxidation and reduction represents a significant challenge in the field of photocatalysis. In this study, hydrothermal/in situ construction Bi atom clusters within 2 Sn O 7 /ZnIn S 4 (BSO/ZIS) heterostructures is reported. These exhibit self‐accelerating charge‐transfer mechanisms facilitated by internal electric fields bonding bridges, resulting highly efficient light absorption capabilities. X‐ray photoelectron spectroscopy (XPS) Kelvin probe force microscopy...
Photocatalytic hydrogen production could sustainably and efficiently convert solar energy. However, a low light utilization ratio limits the wide application. Herein, Moiré-like structure was constructed in TiO2 body to improve absorption by multiple reflections suitable dispersion diffraction based on similar wavelength nick. Furthermore, slightly reduces band gap accelerates separation of photogenerated electrons holes, mass transfer enhanced regular nano-channels Bernoulli phenomenon....
In many single-pulse experiments of X-ray free electron lasers, the spectrum and intensity distribution self-amplifying spontaneous radiation beams fluctuate significantly. It is necessary to perform accurate spectral characterization each pulse. this paper, we present an in-line spectrometer that can observe energy incident single pulse photons in real time. The diffraction achieved by using a high precision transmission crystal bending fixed pressure bending, recorded spatial resolution...
Spherically Bent Crystal Analyzers (SBCAs) are the core optical components of x-ray spectrometers. They have been widely used in many spectroscopy end-stations at synchrotron radiation and free electron laser facilities around world. Owing to monochromatic focal properties SBCAs, spectrometers with high efficiency energy resolution can be well applied study absorption (XAS) emission (XES). Hence, quality SBCAs is key factor determining performance Previously, we investigated Si(444) by using...
Brilliant synchrotron radiation and x-ray free-electron laser facilities have promoted the development of spectroscopy, especially resonant inelastic scattering femtosecond time-resolved spectroscopy. Comparing with flat crystals, spherically bent crystals (SBCs) are widely used in relevant spectrometers for focusing, which will dramatically improve detection efficiency. Therefore, focal properties SBCs should be experimentally well-investigated. Here, we build a device based on Rowland...
X-ray spectroscopy is an important technique for studying the material electronic structure, oxidation state and coordination, which have wide applications in energy catalysis, environmental science fields. The crystals diffract X-rays because their internal atoms are spatially ordered lattice spacing on nanometer scale, similar to wavelength. In this paper, a based bending epoxy adhesive proposed fabricate bent crystal analyzer. radius of convex surface 1‰ smaller than concave one. wafers...
