2020年8月17日 · Using in situ X-ray absorption spectroscopy (XAS), we show that the dominant active site for HER is the Ni single atom in its intrinsic environment in an acidic electrolyte, …

The absorption spectra of Ni-QDs are indicated via ultraviolet-visible spectroscopy (UV-vis) at 390, 655, and 731 nm of wavelengths, which can be assigned to absorption peaks of Ni (OH) …

A series of nickel dithiolene complexes Ni [S2C2 (CF3)2]2n (n = −2, −1, 0) has been investigated using Ni L- and K-edge X-ray absorption spectroscopy (XAS). The L3 centroid shifts about 0.3 …

X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy that indicates the features in the X …

2011年7月1日 · The pre-edge region of the XANES provides with the information on the local electronic structure at the absorbing Ni atoms in the presence of the core-hole. In particular, …

2023年2月17日 · In this review, we provide an overview of the fundamental concepts of X-ray absorption spectroscopy (XAS) and then comprehensively review the setup and application of …

This work has investigated the formation of the local structure order around Ni in Hf‒Cu‒Ni glassy ribbons by employing X‒ray absorption near edge structure (XANES) and extended X‒ray …

2007年11月15日 · The structural origins of ion recognition by electrochemically addressable poly [Ni (salen)] thin films are explored using in situ X-ray spectroscopy. XANES and EXAFS …

The X-ray absorption near edge structure (XANES) spectrum after the treatment has two specific peaks in the absorption edge region, whereas the XANES spectrum before the treatment is …

We analyzed Ni phosphide catalysts using X-ray absorption fine structure (XAFS) to elucidate the structure-catalytic activity relationship.
