Co-ACCESS Laboratory

Co-ACCESS Lab

The Catalysis science group at SSRL operates a 400 sq foot wet chemistry laboratory specifically designed for catalysis studies. Typical activities in the lab include catalyst synthesis, off-line catalyst treatments, off-line testing of in-situ/operando cells for use at the beamlines, and prototyping of catalysis cells. The lab is equipped with a 6 ft and 4 ft fume hoods, two gas cabinets for flammable and toxic gases, an argon glove box, and ovens and furnaces. The lab is fully stocked with a diverse array of equipment necessary for the catalysis researcher and is available to collaborators.

Lab Functionality:

  • Catalyst synthesis
  • Off-line catalyst treatments
  • Off-line experimental testing
  • Prototyping/testing of cells
