Ultradeep Removal of Acetaldehyde from Ethanol through Catalytic Hydrogenation with Highly Dispersed Ag Nanoparticles Supported on Phenyl-Modified SiO2

“…Typical bands related to the formation of a condensed siloxane network for SiO 2 materials were detected for all of the materials (1082, 798, and 469 cm –1 ). − The presence of −Ph (Figure c) led to the emergence of the absorption peaks at 739 and 696 cm –1 , which can be attributed to the C–H bending vibration peak of the benzene ring. At the same time, the appearance of Si–C, CC, and C–H (1143, 1427, and 3059 cm –1 , respectively) characteristic absorption peaks further proved the successful introduction of phenyl in the material of Ag/Ph-SiO 2 . In addition, there was another absorption band emerging at about 957 cm –1 in all of the spectra, which belongs to the Si–O vibration in silanol .…”

“…Si species percentage (%) a entry material further proved the successful introduction of phenyl in the material of Ag/Ph-SiO 2 . 38 In addition, there was another absorption band emerging at about 957 cm −1 in all of the spectra, which belongs to the Si−O vibration in silanol. 32 With the introduction of phenyl on the surface, the intensity of this absorption band turned weaker when it was compared with that of Ag/SiO 2 (Figure 3b,c), implying a decrease in the amount of silanol.…”
