Figure 2From: New nanostructured silica incorporated with isolated Ti material for the photocatalytic conversion of CO2 to fuelsTEM images. (a) KIT-6 (calcined), (b) Ti-KIT-6 (calcined, Si/Ti = 200), (c) Ti-KIT-6 (calcined, Si/Ti = 100), and (d) Ti-KIT-6 (calcined, Si/Ti = 50). The blue arrow shows the preserved meso-structure. The red arrow indicates the partial collapse of the mesoporous structure.Back to article page
