Abstract
Energy is the main problem facing most of the countries. Hydrogen has been considered as an effective clean energy source to substitute the fossil fuel. Water photo-splitting is considered the most preferable remedy to produce hydrogen from costless and renewable source of energy; solar energy.
TiO2 has been studied extensively as a photocatalyst in water photo-splitting material but it has a poor performance under visible light region due to its wide band gap. A lot of mechanisms have been introduced to fix this problem among, like doping some low band gap energy materials with the titanium and then modifying its morphology as nanofibers (NFs) to increase its efficiency under sun light irradiation. After producing hydrogen it could be stored in one of those hydrogen storage materials like Ammonia Borane (AB) which have a large potential to be used as it could release the hydrogen by a photocatalyst via sun light as well.
In this study, novel Zn, Fe co-doped NFs are introduced as photocatalyst for water photo-splitting to reduce the Ti band gap and make it effective under sun light ( meaning not only the UV region but also the visible light region as well). The introduced NFs were synthesized by calcination of electrospun NF mats, with studying different iron and zinc concentrations at different temperatures to optimize the photocatalytic reaction.
The best NFs results in the photocatalytic water splitting experiments were composed of (0.6g (3%) iron acetate, 0.28g (20%) zinc acetate, 1.8ml titanium isopropoxide (TIPO) and 20ml (PVP) soln. (the stock sol. made by dissolving 1g PVP in 7.5 ml ethanol) mixed all together and electrospuned at 20KV then calcinating the electrospun mat at 600°C for 1h at a rate of 5°C/min. The porosity, morphology and performance of the introduced NFs were characterized by standard techniques; SEM, FE-SEM, TEM and XRD.
