photocatalyticadj.

Brit.

/ˌfəʊtəʊkatəˈlɪtɪk/, U.S.

/ˈˌfoʊdoʊˌkædəˈlɪdɪk/

Forms: 1900s– photocatalytic, 1900s– photokatalytic (rare).

Origin: Formed within English, by compounding. Etymons: photo- comb. form, catalytic adj.

Etymology: < photo- comb. form + catalytic adj. (see quot. 1895 at main sense). Compare German photokatalytisch (J. Plotnikow Photochemie (1910) ii. 72). Compare photocatalysis n.

Chemistry.

Relating to or exhibiting photocatalysis.
