Hence, a recent flourish of studies have been inspired to develop environmental-friendly and renewable fuels [1]. Specifically, the usage of photocatalytic water splitting for hydrogen production is an desirable approach in the field of power conversion with abundant solar energy, because the pioneering report of photoelectrochemical water splitting was published in 1972 [2]. At the moment, lots of photocatalysts, such as TiO2 [3], WO3 [6,7], g-C3 N4 [80], ZnO [113], and metal complexes [146], have been employed for the photocatalytic water splitting reaction. Having said that, it has been demonstrated that most of these photocatalysts with wide band gaps are only active under UV irradiation. Hence, it is essential to create a very active photocatalyst using a sufficiently narrower bandgap for effective visible-light-driven hydrogen production. So far, nitride [17,18] or metal oxynitrides [19,20], absorbing visible light with a bigger wavelength variety, have already been located to become capable of splitting water into hydrogen and oxygen below visible-light illumination. Amongst them, GaN:ZnO solid remedy possesses a wurtzite-type structure using a d10 standard electronic configuration, which has been actively investigated [21,22]. It shows a narrower band gap, ranging from two.4 2.8 eV [23,24], which may be ascribed towards the p-d repulsion in the valence band involving Ga3d/Zn3d and N2p/O2p [25]. However, as for GaN:ZnO strong option, as a result of lack of H2 evolutionAppl. Sci. 2021, 11, 10854. https://doi.org/10.3390/apphttps://www.mdpi.com/journal/applsciAppl. Sci. 2021, 11,2 ofsites, it’s necessary to employ a cocatalyst that plays a vital part in giving active web-sites and enhancing the charge separation for photocatalytic redox reactions [268]. Rh2-y Cry O3 , as a traditional cocatalyst, has been found to become capable of promoting the realization from the photocatalytic water splitting [29,30]. For that reason, high-efficiency GaN:ZnO strong solutions decorated with cocatalyst of Rh2-y Cry O3 had been designed and ready. Normally, GaN:ZnO is synthesized by nitriding the mixture of Ga2 O3 and ZnO beneath anhydrous NH3 gas flow, and calcinating it for any fairly extended reaction period to guarantee a successful formation of solid resolution [21,31,32]. However, the as-prepared GaN:ZnO possesses a non-uniform elemental distribution of Zn and Ga right after long-term nitriding [24,33]. Herein, it’s considerable to create a facile and versatile strategy to prepare the GaN:ZnO solid option with larger homogeneous particles. In current years, electrospinning has been established as a easy and extensively made use of technologies for the preparation of nanofiber components with a larger distinct surface location and far better light harvesting potential [346]. The electro-spun nanofibers also show superior recoverable character in comparison to Nitrocefin MedChemExpress nano-powders [37]. Furthermore, the issue in the elemental aggregation of GaN:ZnO strong resolution might be effectively eliminated by immobilizing the elements of Ga and Zn on polyacrylonitrile (PAN) during the electro-spun method [38]. In this study, we present for the first time nanorod GaN:ZnO solid options ready working with an electrospinning strategy for photocatalytic H2 production beneath visible-light irradiation.
