Morphology

noncatalytic = catalytic (transparent) = non + catalytic

The prefix 'non-' straightforwardly negates the adjective 'catalytic', so the meaning is directly derivable.

Etymology

Noncatalytic is built from non- meaning 'not' and catalytic, from catalyst, a word that originally meant something that 'helps a change happen'. So noncatalytic means 'not using a catalyst' and describes a process or surface that does not speed up a chemical reaction.
