| The present application provides a three-dimensional stacked photocatalytic device, which comprises a support frame and a first integrated component. The first integrated component includes a first bottom plate, a first receiving tank and a first top plate. The first bottom plate is pivoted on a first pivot hole of the support frame, the first accommodation slot is disposed on the first bottom plates, and a first photocatalytic component is disposed in the first accommodation slot, and the first top plate is disposed on the first accommodating grooves, wherein a light passes through the first top plate and the first photocatalytic component sequentially, causing the first photocatalytic component to generate a gas, and the first bottom plate is configured to rotate on the first pivot hole and drive the first integrated component to rotate for adjusting the irradiation angle of the first photocatalytic component. |
