Abstract
The visible light responsive photo catalyst of the disclosure includes at least one tungsten oxide particle and at least one co-catalyst particle supported on a surface of the tungsten oxide particle, in which 20% or more of the co-catalyst particles of a plurality (100 or more) of the co-catalyst particles each of whose primary particle diameter is measurable by an electron microscopic image of the visible light responsive photocatalyst are non-aggregates and each have a primary particle diameter from 6 nm to 20 nm.
Claims8
A visible light responsive photocatalyst comprising:
- at least one tungsten oxide particle;
- and
- at least one co-catalyst particle supported on a surface of the tungsten oxide particle,
- wherein 20% or more of the co-catalyst particles of a plurality (100 or more) of the co-catalyst particles each of whose primary particle diameter is measurable by an electron microscopic image of the visible light responsive photocatalyst are non-aggregates and each have a primary particle diameter from 6 nm to 20 nm.
A visible light responsive photocatalyst comprising:
- a tungsten oxide particle;
- and
- a plurality of co-catalyst particles supported on a surface of the tungsten oxide particle,
- wherein an average primary particle diameter of a plurality of co-catalyst particles which are non-aggregates each of whose primary particle diameter is measurable by an electron microscopic image of the visible light responsive photocatalyst is from 6 nm to 20 nm.
A visible light responsive photocatalyst comprising:
- a tungsten oxide particle;
- and
- a plurality of co-catalyst particles supported on a surface of the tungsten oxide particle,
- wherein 50% or more of the tungsten oxide particles of a plurality (100 or more) of the tungsten oxide particles each of whose aspect ratio (ratio (b/a) of a major axis b to a minor axis a of a primary particle) is calculable from an electron microscope image of the visible light responsive photocatalyst each have an aspect ratio from 1.3 to 10.
