naphthol blue meaning in English

萘酚蓝

The photocatalytic activities of the xw11 / tio2 ( x = p , si , ge ) composite films were tested via degradation of aqueous azo - dyes , congo red ( cr ) and naphthol blue black ( nbb ) . it was observed that the photocatalytic activities of the three composite films are much higher than that of the pure tio2 film , mainly attributed to the synergetic effect between xw11 and tio2 , i . e . , xw11 - catalyzed electron transfer from the conduction band ( cb ) of photoexicited tio2 to itself
结果表明三种复合膜均具有远高于纯tio _ 2膜的活性，主要归因于复合膜材料中多金属氧酸盐和tio _ 2之间存在的协同效应，即作为强电子受体的多金属氧酸盐接受tio _ 2受光激发形成的导带光生电子，延长了空穴-电子的再复合时间，同时自身仍具有光活性。
