Photocatalytic properties of atomic layer deposited TiO2 inverse opals and planar films for the degradation of dyes

Porous V2O5/TiO2 Nanoheterostructure Films with Enhanced Visible-Light Photocatalytic Performance Prepared by the Sparking Method

“…Surface modification is known to be able to promote photocatalytic performance by providing more effective interfacial properties. In particular, the large surface areas of 1-D structures and porous morphology are preferred in the design [ 5 , 6 ]. Moreover, composite films with a narrow band gap semiconductor are preferred, which can lead to superior performance of the pure TiO 2 films [ 7 , 8 , 9 ].…”

Atomic Layer Assembly Based on Sacrificial Templates for 3D Nanofabrication

“…Polystyrene sphere (PSS) templates are most commonly used and easily removed by calcination. Inverse opal TiO 2 nanostructures [86] were synthesized by ALA using a template with ordered layers of PS spheres deposited on a Si substrate by spin coating, as illustrated in Figure 9f, where the IO nanostructures showed giant photocatalytic enhancement for the degradation of methylene blue than that of planar TiO 2 films. Similarly, a TiO 2 /MoS 2 core/shell inverse opal structure was fabricated based on ALA on a self-assembled multilayer PSS template, as presented in Figure 9g.…”

Visible-light photocatalytic degradation of dyes by TiO2–Au inverse opal films synthesized by Atomic Layer Deposition

“…Recently, several works have reported the synthesis of TiO 2 IO decorated with noble-metal nanoparticles for photocatalysis applications under visible light illumination [29][30][31][32]. The synthesis of this type of structures has been developed by sol-gel methods, electrochemical deposition, chemical vapor deposition and atomic layer deposition by using self-assembled templates of polymer beads, followed by calcination to remove the template [26,33]. Among these techniques, the ALD approach offers an excellent control of the synthesized film at the expense of a lower growth rate than the classical Chemical Vapor Deposition (CVD) process.…”
