“…Furthermore, Zhang et al [ 25 ] significantly reduced the interface resistance and greatly improved their ability to photoelectrochemical decompose water by forming a strong interface contact of the S–O covalent bond at the interface of the Cu 2 S/Fe 2 O 3 heterostructure. In our previous work [ 26 ], the Ti–O–Zr bonded TiO 2 /ZrTiO 4 heterointerface was constructed by growing ZrTiO 4 in situ on TiO 2 to enhance the transport of photogenerated carriers. However, the possibility of forming a chemically bonded TiO 2 /TiN heterostructure and its synergistic enhancement of photocatalytic activities with the LSPR effect of TiN have yet to be explored.…”

Plasmonic effect-enhanced Z-type heterojunction photocatalysts comprise a promising solution to the two fundamental problems of current TiO2-based photocatalysis concerning low-charge carrier separation efficiency and low utilization of solar illumination. A plasmonic effect-enhanced TiN@anatase-TiO2/rutile-TiO2 Z-type heterojunction photocatalyst with the strong interface of the N–O chemical bond was synthesized by hydrothermal oxidation of TiN. The prepared photocatalyst shows desirable visible light absorption and good visible-light-photocatalytic activity. The enhancement in photocatalytic activities contribute to the plasma resonance effect of TiN, the N–O bond-connected charge transfer channel at the TiO2/TiN heterointerface, and the synergistically Z-type charge transfer pathway between the anatase TiO2 (A-TiO2) and rutile TiO2 (R-TiO2). The optimization study shows that the catalyst with a weight ratio of A-TiO2/R-TiO2/TiN of approximately 15:1:1 achieved the best visible light photodegradation activity. This work demonstrates the effectiveness of fabricating plasmonic effect-enhanced Z-type heterostructure semiconductor photocatalysts with enhanced visible-light-photocatalytic activities.

“…The sol-gel method mixes components homogeneously at the molecular level, which is convenient [33] for the dopant incorporation process in the material matrix [28]. Ning et al [29] observed the presence of Ti-O-Zr links in ZrTiO 4 gel produced using the sol-gel process, which possesses a higher oxygen vacancy concentration that enhances photocatalytic activity. Previous studies of doping on ZrTiO 4 composite materials with transition metals Fe, Cu, Zn, and Co have been done.…”

Iron (Fe) and nitrogen (N) were introduced as dopants into zirconium titanate (ZrTiO4) in order to study the codoping effects of nitrogen on iron-doped zirconium titanate (Fe,N-codoped ZrTiO4) composite. Titanium tetraisopropoxide (TTIP), zirconia (ZrO2), urea, and iron(II) sulfate heptahydrate were used as the source of TiO2, semiconductor supports, source of nitrogen, and iron, respectively. A specific amount of iron (1, 3, 5, 7, and 9 wt.%) and a fixed nitrogen content (10 wt.%) were doped into the ZrTiO4 lattice. Various calcination temperatures (from 500 to 900 °C) were also applied to investigate the crystal structure of the composite. The composites were characterized by X-ray powder diffractometer (XRD), Fourier-transform infrared spectrophotometer (FT-IR), scanning electron microscope with energy dispersive X-Ray spectrometer (SEM-EDX), and specular reflectance UV-Vis (SR-UV). The lowest bandgap energy of 2.62 eV was obtained in the composite with 3 wt.% of Fe and 10 wt.% of N calcined at 500 °C.
