Interfacial synthesis of polyaniline–polypyrrole on electrospun vanadium oxide-embedded TiO₂ nanofibers with enhanced photocatalytic performance

Abstract

Designing high-performance TiO2-based photocatalysts with reduced bandgap is obligatory towards utilizing abundant sunlight. In this study, a novel hybrid was fabricated by interfacial polymerization of polyaniline (PANi) and polypyrrole (PPy)...

Configuration Effect of Plasmonic Vanadium–Titanium Solid Solutions for Photo-oxidation of Benzyl Alcohol

“…Pure TiO 2 , while being active under UV light, exhibits low BA conversion efficiency and poor BAD selectivity when exposed to visible light due to its wide-ranging band gap energy (3.0–3.5 eV) and the rapid recombination of charge carriers, which generally limits its practical applications. , In this context, VO x –TiO 2 systems are a promising candidate that offers improved performance and are therefore highly desirable alternatives to further enhance the photocatalytic activity for the oxidation of BA to BAD. Several structural configurations of VO x –TiO 2 catalysts have been studied across a range of significant reactions, including the NH 3 selective catalytic reduction, − oxidative dehydrogenation (such as methanol, , ethanol, , cyclohexane, and triethylamine), the combustion of volatile organic compounds (VOCs), and photocatalytic reactions. − In the literature, current research indicates that the structure of the interface and the interaction between the VO x and TiO 2 components vary depending on the configuration of the VO x –TiO 2 composites, which influences their catalytic properties. For instance, VO x species residing on TiO 2 (001) faces exhibit enhanced performance in the selective NO reduction with NH 3 than their corresponding VO x /TiO 2 (101) counterparts.…”
