2012年2月1日 · In this work, simultaneous time-resolved (STR) analysis of Ni 2 P/MCM-41 under thiophene HDS conditions was carried out using in situ quick X-ray absorption fine structure (QXAFS) analysis, in situ Fourier transform infrared (FTIR) spectroscopy and mass spectroscopy.

2022年11月1日 · An integrated quick-scanning X-ray absorption fine structure (QXAFS) system has been developed for general XAFS beamlines with double-crystal monochromator to conduct time resolved researches. Based on the field programmable gate array (FPGA), it is flexible to adopt the programming control of both the motion of monochromator and data ...

The quick-scanning XAFS (QXAFS) method is achieved at the BL14W1 XAFS beamline at the Shanghai Synchrotron Radiation Facility based on the EPICS and LabVIEW systems. This is realised by the unprecedented use of LabVIEW's data logging and supervisory control module for communication with EPICS in syn …

2025年1月1日 · To address this issue, we utilized a transient kinetic quick X-ray absorption fine structure (QXAFS) approach to study MEA cathode electrocatalysis, aiming to understand the ORR performance gap between RDE and MEA.

Here, we employ operando quick X-ray absorption fine structure (QXAFS) spectroscopy coupled with machine-learning based data analysis and surface-enhanced Raman spectroscopy (SERS) to investigate the time-dependent chemical and structural changes in catalysts derived from shape-selected ZnO/Cu 2 O nanocubes under CO 2 RR conditions at current ...

Pt L3- and Ru K-edge quick-scanning XAFS (QXAFS) spectra for standard Pt and Ru foils, respectively, revealed the stability of the q-scan technique. The results also demonstrated the beamline’s ability to collect XAFS spectra on a sub-second timescale.

2017年4月6日 · A new quick-scanning X-ray absorption fine-structure (QXAFS) system has been established on beamline 1W1B at the Beijing Synchrotron Radiation Facility. As an independent device, the QXAFS system can be employed by other beamlines equipped with a double-crystal monochromator to carry out quick energy scans and data acquisition.
