Here are a few examples of recent studies conducted using the ambient table at the SXRMB beamline:

Researchers from McGill University have developed copper nanocluster catalysts for converting carbon dioxide (CO₂) into methane, a cleaner energy source. In-situ measurements were carried out at the ambient table endstation using a modified flow cell, as shown below.

For further information, please refer to the following paper: Selective CO2 to methane conversion

In-situ experiment was performed in a reactor cell as shown below. This reactor is equipped with water-cooled ceramic heaters, with gas inlets for He and/or DMTHF. Powder sample was pressed into pellet, sitting in a sample holder placed onto the heater.

For in-situ experiments, 6–8 mg of sample can be loaded into a 6-hole shooter sample holder and placed inside a quartz reactor. The reactor, placed within a tube furnace, is positioned between the first and second ionization chambers to facilitate data collection in transmission mode. In-situ XAS measurements can be conducted in transmission mode using X-ray energies above 5 keV. This setup allows for real-time monitoring of solid-gas reactions under controlled temperature and gas flow conditions, enabling simultaneous XAS data collection.

In-situ Pd K edge and L₃ edge XAS measurements were performed to identify the systematic engineering of active phases of Pd NPs, which are exploited to select reaction pathways for CO₂ electroreduction. The results suggested that the main product, which is either formate or CO, can be selectively produced with high Faradaic efficiencies (>90%) and mass activities in the potential window of 0.05 to −0.9 V with scalable application demonstration.

Experimental setup of in situ XAS for CO₂ electroreduction is shown below, where (a) is the schematic diagram of in-situ XAS cell and (b) is the photograph of in situ XAS cell in working condition.

Here is the full setup for the electroreduction of CO₂ using Pd nanoparticles (NPs):
