文摘

An in situ ATR-IR cell for studies in hot compressed water was designed and tested. Mechanically stable catalyst layers are obtained by spray coating method. Hydrodynamics in the cell were characterized by both experiments and simulation. Cell can perform ATR-IR spectroscopy for aqueous phase reforming of hydroxyacetone.
