Ti dispersion on SBA-15 porous host to enhance photocatalytic hydrogen production

Effective Interactions of Ag Nanoparticles on the Surface of SBA-15 in Performing Deep Desulfurization of Real Diesel Fuel

“…2 Total pore volume at P/P0 = 0.996. HAADF-STEM images for pure SBA-15 (Figure 3a,b) confirm the well-ordered mesoporous hexagonal structure of the SBA-15 matrix [30][31][32]. As shown in Figure 3c, the structure of the original material was preserved after modification with Ag(I), which is in line with the previous characterization results.…”

Reusable TiO2‐SBA‐15 Synthesized by Different Silica/Titania Ratios for Photodegradation

“…As can be seen in Figure 1a, the XRD patterns display a reflection peak at 2θ ffi0.8°(100) and clearly show that the SBA-15 and all the TiO 2 /SBA-15 (R) have an ordered hexagonal mesoporous structure, the characteristic of mesoporous silica SBA-15. [20,23] The insertion of titania created the peak shift to higher 2θ angles on the reflection plane (100) and no intensity decrease in all the diffraction peaks. Therefore, no contradiction of lattice parameter (a 0 ) of photocatalyst, obtained from the d100 spacing included in Table 2, was observed.…”

“…In most reports reviewed, the obtained TiO 2 nanoparticles in the synthesized materials were anatase phase, and TiO 2 /SBA-15 photocatalysts gave approximately seven times higher photocatalytic activity than commercial P25 Degussa or other synthesized nanoparticles form, verifying the advantage of incorporating the TiO 2 in the SBA-15 matrix. [10,13,20] As can be seen in Table 1, the TiO 2 /SBA-15photocatalysts have been prepared by the post-synthesis method and direct synthesis under hydrothermal conditions with different titanium sources and loading amounts. [7,8,9,10,13,15,16] In the post-synthesis method, the TiO 2 particles incorporated into the surface of the SBA-15 displayed high photocatalytic activity, since the TiO 2 particles were more accessible to the reactants.…”

Reusable titania-SBA-15 photocatalyst synthesized by different silica/titania ratios for enhancing methylene blue photodegradation

“…Different synthesizing methods have been employed to functionalize SBA-15 with TiO 2 reported by several authors in the literature, the comparing results of these methods are given in Table 1. In most reports reviewed, the obtained TiO 2 nanoparticles in the synthesized materials were anatase phase, and TiO 2 /SBA-15 photocatalysts gave approximately seven times higher photocatalytic activity than commercial P25 Degussa or other synthesized nanoparticles form, verifying the advantage of incorporating the TiO2 in the SBA-15 matrix (Acosta-Silva et al, 2011; Sanches et al, 2018;Wei et al, 2018). Wei et al, 2018).…”
