“…Researchers found that the resulting products via the CT interactions possess unique chemical, biological, and physical properties. The CT complexations are significantly beneficial to non-academic fields (pharmacology, material science, engineering, technology, and medicine) in addition to academia (chemistry, physics, biology, and biochemistry) [12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Tea is the third most consumed beverage in Saudi Arabia (a country in the Middle East) after water and Arabian coffee. Hence, a large amount of consumed tea leaves is discarded as solid waste. Waste tea leaves (WTLs) have no commercial value and could be considered as an environmentally sustainable costless material. This work aimed to manufacture an adsorbent material from the discarded WTLs and charge-transfer (CT) interaction and use this adsorbent material effectively for the removal of different kinds of pollutants from water. The adsorbent material was manufactured in three steps. First, a CrFeO3 metal composite was synthesized from the CT interaction between FeCl3 and CrCl3 with urea. Second, activated carbons were prepared from consumed WTLs using facile and clean treatments of pre-carbonization, and a simple potassium hydroxide (KOH) activation treatment. Finally, the adsorbent material was fabricated by grounding CrFeO3 composite with the activated carbons in a 1:10 molar ratio (metal composite to activated carbons). The prepared materials were characterized spectroscopically and morphologically using FT-IR, XRD, SEM/EDX, and TEM analysis. The synthesized absorbent material was used to adsorb two organic dyes (Azocarmine G2; M1, and Methyl violet 2B; M2), and two commercial pesticides (Tiller 480SL; M3, and Acochem 25% WP; M4) from aqueous solution, and it showed promising adsorption efficacy. The minimum adsorbent material’s dosage to obtain a maximum removal efficiency (R%) for M1, M2, M3, and M4 removal from 100 mL solution (100 mg/L) was 0.11, 0.14, 0.13, and 0.12 g, respectively. The max R% for M1 (96.8%) was achieved in the first 45 min, the max R% for M2, 95.5%, was achieved during the first 55 min, and the max R% for M3 (96.4%) was achieved in the first 35 min, while the max R% for M4, 98.6%, was achieved during the first 35 min.

Narrowband Near-Infrared Perovskite/Organic Photodetector: TCAD Numerical Simulation

et al. 2022

View full text Add to dashboard Cite

Narrowband photodetectors (PD) established in the near-infrared (NIR) wavelength range are highly required in a variety of applications including high-quality bioimaging. In this simulation study, we propose a filter-less narrowband PD based on the architecture of perovskite/organic heterojunction. The most decisive part of the photodetector is the hierarchical configuration of a larger bandgap perovskite material with a thicker film followed by a lower bandgap organic material with a narrower layer. The design of the structure is carried out by TCAD numerical simulations. Our structure is based on an experimentally validated wideband organic PD, which is modified by invoking an additional perovskite layer having a tunable bandgap. The main detector device comprises of ITO/perovskite (CsyFA1−yPb(IxBr1−x)3)/organic blend (PBDTTT-c:C60-PCBM)/PEDOT:PSS/Al. The simulation results show that the proposed heterojunction PD achieves satisfactory performance when the thickness of perovskite and organic layers are 2.5 µm and 500 nm, respectively. The designed photodetector achieves a narrow spectral response at 730 nm with a full width at half-maximum (FWHM) of 33 nm in the detector, while having a responsivity of about 0.12 A/W at zero bias. The presented heterojunction perovskite/organic PD can efficiently detect light in the wavelength range of 700 to 900 nm. These simulation results can be employed to drive the development of filter-less narrowband NIR heterojunction PD.

Ferric chloride salt (FeCl3) is a typical vacant orbital acceptor that accepts electrons from urea molecules. This donor-acceptor interaction yields a Fe3O4 oxide, which can be used for preparing novel adsorbent material. Activated carbon (AC) materials, derived from biomass precursors and used for environmental remediation, have gained increasing attention owing to their sustainability, eco-friendly nature, ease of fabrication, and cost-effectiveness. Globally, a large amount of consumed tea leaf materials is discarded as solid waste. The present study aimed to reuse consumed tea leaves to generate biomass-derived-ACs and coupling AC with Fe3O4 oxide to generate Fe3O4-carbon-based composite for environmental remediation. The synthesized Fe3O4-carbon-based composite was examined to remove four common organic pollutant dye models from an aqueous solution. The effects of several parameters on the adsorption capacity of the synthesized composite were analyzed, and equilibrium data were examined. We found that the synthesized composite displayed promising adsorption activity against the investigated dyes.
