Action spectrum analyses showed that visible light-induced oxidation of 2-propanol by aerated gold-modified titanium(IV) oxide (titania) suspensions is initiated by excitation of gold surface plasmon, and polychromatic irradiation experiments revealed that the photocatalytic reaction rate depends strongly on properties of titania, such as particle size, surface area and crystalline form (anatase or rutile) and on properties of gold deposits, such as size and shape.
作用光谱分析表明，可见光诱导的充气金修饰二氧化钛（TiO₂）悬浮液对异丙醇的氧化反应是由金表面等离子体的激发引发的，多色辐照实验表明，光催化反应速率强烈依赖于二氧化钛的性质，如粒径、表面积和晶型（锐钛矿或金红石），以及金沉积物的性质，如尺寸和形状。
