Controlling the size of connecting windows in three-dimensionally ordered macroporous TiO2 for enhanced photocatalytic activity

Multilayer TiO2 Inverse Opal with Gold Nanoparticles for Enhanced Photocatalytic Activity

“…It can be concluded that IO structures with larger pores on top (200/400 samples) with and without AuNPs showed a larger photocatalytic activity compared to IO structures with small pores on top (400/200 samples) both under UVA and visible light. It is known that larger-size IO structures are more stable and have a higher efficiency for photocurrent compared to smaller-size IO structures . Furthermore, multilayer TIO structures loaded with AuNPs displayed photocatalytic activity under visible light via the plasmonic coupling of AuNPs with visible light.…”

“…It is known that larger-size IO structures are more stable and have a higher efficiency for photocurrent compared to smaller-size IO structures. 53 Furthermore, multilayer TIO structures loaded with AuNPs displayed photocatalytic activity under visible light via the plasmonic coupling of AuNPs with visible light. Finally, reproducibility and stability of the results were confirmed for Au-TIO 200/400 with UVA light irradiation shown in Figure 9c.…”

Recent Progress of Three‐dimensionally Ordered Macroporous (3DOM) Materials in Photocatalytic Applications: A Review

“…[33,34] The controllable pore size and pore wall of the 3DOM structure provides the possibility to achieve high-efficient photocatalysis. [35] In addition, the pore size of 3DOM materials in the range of optical wavelength can produce special optical effects with light, including the photonic bandgap (PBG) effect, slow photon effect, and band stop reflection, leading to high phototrapping efficiency. [36] In the past decades, various 3DOM materials such as 3DOM TiO 2 , [37] 3DOM WO 3 , [38] 3DOM Bi 2 WO 6 , [39] and 3DOM g-C 3 N 4 , [40] have been developed and exhibited high photocatalytic activity.In recent years, three-dimensionally ordered macroporous (3DOM) materials have attracted tremendous interest in the field of photocatalysis due to the periodic spatial structure and unique physicochemical properties of 3DOM catalysts.…”
