Abstract
Increasing global warming due to NO, CO, and CH, is significantly harming ecosystems and life worldwide. One promising methodology is converting pollutants into valuable chemicals via photocatalytic processes (by reusable photocatalysts). In this context, the present work aimed to produce a NbO photocatalyst nanofiber system by electrospinning to convert CO. Based on the collected data, the calcination at 600 C for 2 h resulted in the best condition to obtain nanofibers with homogeneous surfaces and an average diameter of 84 nm. As a result, the NbO nanofibers converted CO mostly into CO and CH, reaching values around 8.5 mol g and 0.55 mol g, respectively.
Highlights
Various methodologies have been developed to remove pollutants from different types of media, and to address growing environmental quality concerns
The results indicate that the pseudohexagonal TT-Nb2 O5 phase showed greater efficiency, more than 62% degradation
The thermogravimetric analysis indicated the loss of mass and the polymeric degradation events when the fibers were subjected to thermal heating
Summary
Various methodologies have been developed to remove pollutants from different types of media, and to address growing environmental quality concerns. In this context, heterogeneous photocatalysis is receiving attention due to its ability to remove and degrade contaminants, recover the photocatalyst, and reuse it in new cycles [1,2]. Zeng et al [8] investigated the Cu2 O nanowire incorporation in titanium carbide (Ti3 C2 ). These authors have confirmed the enhancement efficiency in CO2 to methanol conversion, causing an increase in the production, around 8.25 times compared to the free
