摘要： It is possible to obtain a visible light-responsive photocatalytic nanoparticle dispersion liquid containing copper-containing titanium oxide nanoparticles by subjecting an aqueous peroxotitanic acid solution containing a copper compound to hydrothermal reaction for crystallizing the aqueous solution by means of heat under high pressure. The visible light-responsive photocatalytic nanoparticle dispersion liquid thus obtained exhibits excellent dispersion stability of titanium oxide nanoparticles within a water-based dispersion medium even when left in a cold and dark indoor area for a long period of time, expresses photocatalytic activity even in visible light (400 to 800 nm) alone, and can easily create a photocatalytic thin film which is extremely transparent and exhibits excellent durability, and in which the state of copper coordination when exposed to heat or ultraviolet rays is stable and cannot be easily modified.

摘要： The present invention relates to a dispersion liquid of titanium oxide-tungsten oxide composite photocatalytic fine particles that is characterized by having two types of photocatalytic fine particles dispersed in an aqueous dispersion medium, the fine particles including i) fine particles of titanium oxide that contain a peroxotitanium component and a copper component and ii) fine particles of tungsten oxide. The present invention can provide a dispersion liquid and the like that can be used to conveniently manufacture a photocatalytic thin film that demonstrates photocatalytic activity even within visible light (400-800 nm) only, exhibits high antibacterial performance, is highly durable, and wherein the state of copper coordination is stable against exposure to heat and ultraviolet rays and is not easily modified. The dispersion liquid is a dispersion liquid of titanium oxide-tungsten oxide composite photocatalytic fine particles that contains copper-containing titanium oxide fine particles.

摘要翻译： 通过使含有铜化合物的含水过氧钛酸水溶液进行水热反应，可以通过高压下的热使水溶液结晶，从而获得含有铜的二氧化钛纳米粒子的可见光响应光催化剂纳米粒子分散液。 这样得到的可见光响应性光催化剂纳米粒子分散液即使在长时间处于冷暗黑暗的室内区域的情况下也表现出优异的水分散介质中的氧化钛纳米粒子的分散稳定性，即使在可见光下也表现出光催化活性 （400〜800nm），可以容易地制造出极度透明且耐久性优异的光催化薄膜，并且其中当暴露于热或紫外线时铜配位的状态是稳定的并且不容易改性的。
