Ternary NiTiO₃@g-C₃N₄–Au nanofibers with a synergistic Z-scheme core@shell interface and dispersive Schottky contact surface for enhanced solar photocatalytic activity

Abstract

Z-scheme narrow bandgap heterojunctions could efficiently absorb solar light and provide high reduction and oxidation ability for photocatalysis. However, it is difficult to tune the Z-scheme interface charge transfer to...

A review on recent advances in selective and sensitive detection of heavy toxic metal ions in water using g-C3N4-based heterostructured composites

“…135 For example, g-C 3 N 4 has been used as a fluorescent sensor to detect various species such as squamous cell carcinoma antigen, xanthine, Cu 2+ , glutathione, Cr(IV), Fe 3+ , and Hg 2+ . 18,136 To the best of our knowledge, the application of g-C 3 N 4 as a fluorescent sensor for the detection of metal ions is desirable to study the PL properties of g-C 3 N 4 .…”

“…It is, however, toxic at high concentrations and can cause liver or kidney damage after long-term exposure to high levels of copper. 18 Moreover, many brain diseases, such as Alzheimer's and Parkinson's disease, are related to copper. 18 Therefore, the detection of copper is of considerable importance for human health.…”

“…The various nanomaterials, from gold nanoparticles and quantum dots (QDs) to carbon nanotubes (CNTs), graphene oxide (GO), metal-organic frameworks (MOFs), biochar, and MXenes have been widely employed for sensitive and precise determination of metal ions. [8][9][10][11][12][13][14][15][16][17][18] The diverse nanomaterial-based biosensors have been constructed with different signal reporting methods, such as fluorescence, colorimetry, scattering, and electrochemistry. Therefore, new kinds of fluorescent g-C 3 N 4 -based materials have recently captivated the attention of scientists due to their unique properties, such as robust chemical inertness, low-photo bleaching, high quantum yield, low toxicity, good biocompatibility, good water solubility, excellent photostability, easy preparation, etc.…”

Epitaxial Growth of Flower-Like MoS2 on One-Dimensional Nickel Titanate Nanofibers: A “Sweet Spot” for Efficient Photoreduction of Carbon Dioxide

“…Interfacial engineering is a promising dimensionality-dependent technique for sustainable energy applications. A plethora of photocatalytic studies on the heterostructures of NiTiO 3 /gC 3 N 4 , NiTiO 3 /TiO 2 , Fe 2 O 3 / NiTiO 3 , mono/multilayer MoS 2 , MoS 2 nanoflowers, 1D/2D TiO 2 /MoS 2 , MoS 2 /graphene, Bi 2 S 3 /MoS 2 , Au-MoS 2 , NiTiO 3 / MoS 2 , phosphated 2D/3D MoS 2 , CdS/MoS 2 , Cu/MoS 2 , and codoped MoS 2 nanoparticles have been reported (Chang et al, 2014;Parzinger et al, 2017;Du et al, 2018;Qin et al, 2018;Li et al, 2019c;Lee et al, 2019;Lu et al, 2020;Guo et al, 2021;Khan et al, 2021;Liu et al, 2021) but to the best of our knowledge, no study on CO 2 reduction via the 1D/2D NiTiO 3 /MoS 2 structure has been reported.…”

Electrospun light stimulus response-enhanced anisotropic conductive Janus membrane with up/down-conversion luminescence

“…Janus-structured materials [21][22][23][24] are a type of material with two types of properties in one system, which can reduce the adverse interactions among various functions in LCM materials. Electrospinning technology [25][26][27][28][29] is an ideal technical means to prepare Janus-structured one-dimensional materials. The required equipment is simple and easy to realize industrial production.…”
