Cells at B07-B

ES-2 is particularly well suited for easy attachment of small cells to contain liquids or high-pressure gases for operando NEXAFS investigations. Currently two cells are available to users and operated on a regular basis: a micro-reactor for catalytic gas-phase reactions at pressures in the bar range and an electrochemical cell. Both are sealed with SiNx membranes and can be operated in either TEY or TFY mode.

1. Microreactor for In-situ NEXAFS

A low-cost, reliable microreactor developed in collaboration with the University of St Andrews, UK, with the aim of closing the pressure gap for the study of heterogeneous catalysts that require pressures in the 1 bar range.

Temperature range: RT to 350C

Gases available: H₂, O₂, CO, CO₂, He, N₂, Ar...                  

2. Electrochemical cell for In-situ NEXAFS

The electrochemical cell was developed in collaboration with Redox.me for operando X-ray spectroscopy of liquids and electro(photo)catalysts.

Electrolytes allowed: H₂SO₄, NaCl, KCl, K₂CO₃, KHCO₃, KNO₃, KOH, NaOH, NaClO₄, KClO₄, LiCl, KBr, HNO₃ and HCl.

Maximum concentration: 0.5 M.
