Adsorption driven preferential degradation of alkyl phenols on hydrophobic perfluoroalkyl modified {0 0 1}-TiO2

Homojunction and defect synergy-mediated electron–hole separation for solar-driven mesoporous rutile/anatase TiO2 microsphere photocatalysts

“…The H500-BMR/ATM sample shows a characteristic lattice spacing of 0.35 nm, which corresponds to the (101) lattice planes of anatase and the expected lattice spacing of 0.32 nm, which matches well with the (110) planes of rutile. 13,33,[39][40][41][42] The results indicate that the as-prepared samples are a mixed phase of rutile and anatase, which coincides with the XRD and Raman analysis. Surface structures of the as-synthetized samples were measured by X-ray photoelectron spectroscopy, as shown in Fig.…”

Advanced Treatments for the Removal of Alkylphenols and Alkylphenol Polyethoxylates from Wastewater

“…The experiments were performed in alkyl phenol (octyl, nonyl, and heptyl) solutions, the removal of which was monitored by high-performance liquid chromatography with UV detection. The optimal potential of the working electrode was +0.6 V. Fan et al (2019) tested static adsorption of pollutants on the electrode for 2 h, and in a separate experiment, photoelectrocatalytic degradation for 5 h. The perfluoroalkyl-decorated electrode showed approximately twice higher adsorption due to matching polarity with the pollutants, which was confirmed by infrared spectroscopy. Similarly, the developed photocatalytic current upon irradiation was up to twice higher compared to a bare electrode.…”

“…The same research group synthesized two other novel electrodes, namely a {0 0 1}-TiO 2 electrode and the same electrode decorated with hydrophobic perfluoroalkyl groups -a D-{0 0 1}-TiO 2 electrode (Fan et al 2019). Both were used in a threeelectrode system as working electrodes with a Pt counter electrode, a saturated calomel reference electrode, and Na 2 SO 4 as a supporting electrolyte.…”

Designing efficient TiO2-based photoelectrocatalysis systems for chemical engineering and sensing

“…In the other word, the proper faceted TiO2 photoelectrode could improve the efficiency of PEC water splitting 80 . For the PEC degradation application, the adsorption of organic molecules also was strongly affected by different TiO2 facets 81 . Sun et al reported that the adsorption capability of the rutile TiO2 (111) surface towards aldehyde was greater than alcohol and carboxylic acid using in-situ PEC measurements 82 .…”
