A high-throughput, operando-ready X-ray absorption spectroscopy catalytic reaction cell consisting of 4 parallel reactors was designed to collect X-ray absorption near edge structure and extended fine structure spectra under reaction conditions. The cell is capable of operating at temperatures from ambient conditions up to 773 K and pressures from ambient to 2 MPa in a variety of gas environments. The cell design is mechanically simple, and programmable operation at beamline 8-ID (NSLS-II, Brookhaven National Laboratory) makes it straightforward to use. Reactor tube parts were available as-fabricated from commercial sources, while the heating jacket and cell mounting required custom machining.
设计了一种由4个平行反应器组成的高通量、适用于原位操作的X射线吸收光谱催化反应池,用于在反应条件下收集X射线吸收近边结构和扩展精细结构光谱。该反应池能够在各种气体环境中,在从环境温度到773 K的温度以及从环境压力到2 MPa的压力下运行。该反应池设计在机械上很简单,并且在8-ID光束线(美国布鲁克海文国家实验室的NSLS-II)上的可编程操作使其使用起来很简便。反应管部件可从商业来源直接获得,而加热套和反应池安装则需要定制加工。
