Although there are many reviews on the synthesis and applications of g‐C3N4 materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g‐C3N4‐based nanomaterials are not published. In this review, the preparation methods and synthetic conditions for preparing g‐C3N4 with different morphologies, such as conventional bulk g‐C3N4, g‐C3N4 nanosheets, and g‐C3N4 quantum dots, are introduced in detail. By reviewing recent advances in g‐C3N4‐based nanomaterials in ion sensors, biosensors, gas sensors, and humidity sensors, this study provides more comprehensive and in‐depth information for the further design of g‐C3N4‐based sensors with enhanced performance. A brief outlook of g‐C3N4‐based sensors is presented as the conclusion of this review.]]> Mon 28 Nov 2022 18:25:37 AEDT ]]> Green synthesis of porous graphitic carbons from coal tar pitch templated by nano-CaCO₃ for high-performance lithium-ion batteries https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42583 Fri 26 Aug 2022 08:16:36 AEST ]]> A luminescent terbium coordination complex as multifunctional sensing platform https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38173 2(NO3)2 (HPU-10) (H2L = 2,6-bis-(5-pyridin-4-yl-1H-[1,2,4]triazol-3-yl)- pyridine), and demonstrate that this novel chemosensor has the property of ratiometric detection of Zn2+ and Cd2+. The detection limit of HPU-10 sensing Zn2+ and Cd2+ is 0.319 and 0.965 μM, respectively. The sensing mechanism can be explained by (i) the decomposition of HPU-10 and (ii) the recombination of Zn2+ or Cd2+ with ligand forming 2HL--Zn2+ or 2HL--Cd2+, respectively. Moreover, the fluorescent sensor HPU-10 can detect the nitroaromatic compound 2, 4-DNP via a fluorescence quenching mechanism. The detection limits obtained from linear regression curve plots of 2, 4-DNP is calculated to be 1.69 μM. In addition, the possible use of the probe coated paper for tracing the target analytes has also been presented.]]> Fri 06 Aug 2021 13:39:40 AEST ]]>
