“…A variety of 1D nanostructures, including nanotubes, nanobelts, and nanowires, have been coupled with a second semiconductor to build the heterostructure, such as Cu 2 O/TiO 2 nanotubes, [57] CdSeTe/TiO 2 nanotubes, [65] CuO/Cu 2 O nanorods, [50] ZnFe 2 O 4 /TiO 2 nanobelts, [66] and g-C 3 N 4 /NaNbO 3 nanowires. [67] For example, ZnFe 2 O 4 nanoparticles successfully grew on the surface of TiO 2 nanobelts by the hydrothermal method ( Figure 7).…”

Photoreduction of CO2 , which utilizes solar energy to convert CO2 into hydrocarbons, can be an effective means to overcome the increasing energy crisis and mitigate the rising emissions of greenhouse gas. This article covers recent advances in the CO2 photoreduction over heterostructure-based photocatalysts. The fundamentals of CO2 photoreduction and classification of the heterostructured photocatalysts are discussed first, followed by the latest work on the CO2 photoreduction over heterostructured photocatalysts in terms of the classification of the coupling semiconductors. Finally, a brief summary and a perspective on the challenges in this area are presented.

“…The improved energy conversion efficiency accredited to the higher Voc = 0.767 V and Jsc = 10.16 mA/cm 2 , that are considerably higher than those of pristine TiO 2 based photoanode. The improved conversion efficiency of magnetic ZnFe 2 O 4 @ TiO 2 nanofibers based DSSCs could not only be attributed to distinctive structure but also from the incorporation of ZnFe 2 O 4 that have comparatively small band-gap energy (1.9 eV) [24]. Obviously, ZnFe 2 O 4 can promotes the photoresponse of TiO 2 nanofibers to the visible light region and thus improve the utilization of solar light.…”

“…However, grain boundaries effect can also be restricted by using TiO 2 nanofibers based catalysts [8,23]. Moreover, among the spinel ferrite compounds Zinc Ferrite (ZnFe 2 O 4 ), a semiconductor shown to be a promising inorganic sensitizer for TiO 2 photocatalyst because it could not only efficiently extent the photoresponse of TiO 2 under wide region of solar light but facilitates the separation of photo-induced charges and lowering the charge transfer resistance [24][25][26]. Thus, the incorporation of trace impurities of ZnFe 2 O 4 into TiO 2 nanofibers had a great effect on improving the overall photocatalytic efficiency [6,12,[27][28][29][30].…”

In this study, magnetic Zinc Ferrite (ZnFe 2 O 4 )@TiO 2 nanofibers were prepared by low cost and nontoxic route; hydrothermal technique followed by electrospinning process. The prepared magnetic ZnFe 2 O 4 @TiO 2 nanofibers were morphologically and structurally analyzed by X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), and thermal gravimetric analysis (TGA). The prepared magnetic ZnFe 2 O 4 @TiO 2 nanofibers were utilized as photoanode for the fabrication of dye-sensitized solar cells (DSSCs) and presented applicable performance with 4.2% overall conversion efficiency with high short circuit current density (J SC ) of 10.16 mA/cm 2 . The maximum ∼42% incident photo-to-current conversion efficiency (IPCE) value was also recorded at 520 nm. In addition, ZnFe 2 O 4 @TiO 2 nanofibers were not only possessed the good conversion efficiency, but also shown excellent photocatalytic efficiency with magnetic properties towards the dye remediation. Prepared ZnFe 2 O 4 @TiO 2 nanofibers can be considered as a promising material for energy conversion and environmental applications.

“…In addition, the other dopants like Cu, which can absorb the longer wavelength light than Fe [19], should be used at lower positioned layers since the wavelength of penetrating light becomes long through higher positioned photocatalyst by losing energy [38]. This idea is similar to the concept of the hybrid photocatalyst using two photocatalysts having different band gaps [43][44][45].…”

Fe-doped TiO 2 (Fe/TiO 2 ) film photocatalyst was prepared by sol-gel and dip-coating process and pulse arc plasma method. The effect of pulse number on the CO 2 reduction performance with the Fe/TiO 2 was investigated in this study. In addition, the effect of reductants such as H 2 O, H 2 , and NH 3 /H 2 O on the CO 2 reduction performance with the Fe/TiO 2 photocatalyst was also investigated. The characteristics of the prepared Fe/TiO 2 film coated on a netlike glass fiber which is a base material were analyzed by SEM, EPMA, EDX, and EPMA. Furthermore, the CO 2 reduction performance of the Fe/TiO 2 film was tested under a Xe lamp with or without ultraviolet (UV) light. The results show that the CO 2 reduction performance with the pulse number of 100 is the best with H 2 O and/or H 2 as reductant under UV light illumination, while that with the pulse number of 500 is the best when NH 3 /H 2 O is used as reductant. On the other hand, the CO 2 reduction performance with the pulse number of 500 is the best under every reductant condition without UV light illumination. The highest CO 2 reduction performance with the Fe/TiO 2 is obtained under H 2 + H 2 O/CO 2 condition, and the best moral ratio of total reductants to CO 2 is 1.5 : 1.
