Coating of anatase titania on clinoptilolite by metal organic chemical vapor deposition method: enhanced mesoporosity and photocatalytic activity

A nanoprecursor method for successfully synthesizing clinoptilolite with high-crystallinity and resultant effects on CO2/CH4 selective adsorption

“… 22 While, the band at 405 cm −1 was assigned to the vibration of Si–O–Al in the framework of CP. 23 However, the bands in the Raman spectra of solution-SP ( Fig. 2C ) were different from those of solid-SP ( Fig.…”

Removal of Emerging Organic Pollutants by Zeolite Mineral (Clinoptilolite) Composite Photocatalysts in Drinking Water and Watershed Water

“…The present composites with larger surface areas exhibited better photocatalytic activity towards TPA under UVC illumination than the commercial Degussa P25 and anatase. Elghniji et al [112] reported the synthesis of TiO 2 /CP by the metal-organic chemical vapour deposition method (MOCVD) for the first time. The photocatalysis activity of TiO 2 /CP composites was determined by measuring the degradation efficiency of salicylic acid (SA) under UV light irradiation.…”

Salicylic Acid-Modified Sm-TiO2 for Photoluminescence and Photocatalysis under Real Sunlight: Synergistic Effects between Ligand-to-Metal Charge Transfer (LMCT) and Sm3+ Dopant

“…All the SA surface-modified samples show new bands at 1389 and 1540 cm −1 , characteristic of symmetric and antisymmetric vibration of COO − groups in −COOTi species. 31 The disappearance of C−OH bands is likely due to the involvement of the phenolic group in the formation of the SA-TiO 2 complex. An important finding from the IR spectra is that the SA benzene ring bands are also affected by the new environment, and the C�C peaks are found at 1468, 1457, and 1606 cm −1 (dotted arrows), indicating that changes in electronic distribution are propagated to the whole aromatic ring.…”
