Among them, g-C₃N₄/BiOI and g-C₃N₄/Bi₄O5I₂ are type-I heterojunction, and g-C₃N₄/Bi₅O₇I belongs to type-II heterojunction. The photocatalyitc activity is surveyed by decomposition of diverse industrial contaminants, including methyl orange, bisphenol A and tetracycline hydrochloride under visible light irradiation (λ > 420 nm). It is found that g-C₃N₄/Bi₅O₇I shows largely enhanced photodegradation performance compared to g-C₃N₄/BiOI and g-C₃N₄/Bi₄O5I₂. The much higher photocatalytic activity of g-C₃N₄/Bi₅O₇I is attributed to the enhanced specific surface area, more efficient charge separation and surface transfer efficiency and increased density of charge carriers owing to the formation of type-II heterojunction. The study provides a reference for in situ fabrication of hierarchical photocatalysts with diverse heterojunction types for optimizing photocatalytic activity.]]> Thu 17 Jun 2021 12:50:03 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7210 Sat 24 Mar 2018 08:39:56 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9350 Sat 24 Mar 2018 08:36:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:2963 Sat 24 Mar 2018 08:30:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:2499 Sat 24 Mar 2018 08:27:42 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21069 Sat 24 Mar 2018 07:59:25 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18537 Sat 24 Mar 2018 07:50:11 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5163 Sat 24 Mar 2018 07:49:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5190 Sat 24 Mar 2018 07:47:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5498 Sat 24 Mar 2018 07:47:01 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30966 Sat 24 Mar 2018 07:27:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22092 0.67.

The optical, electrical, morphological, surface, structural characteristics of the fabricated BHJ PSCs were systematically examined. The atomic force microscopy and X-ray photoelectron spectra measurements confirmed the structural reorganization, phase separation of polymer and fullerene domains resulting in the formation of well-ordered blend in the additive based devices. BHJ PSCs fabricated with P3HT:PC₆₁BM:2-DHP and P3HT:PC₆₁BM:2,4-DHP yielded a best power conversion efficiency (PCE) of 4.35% and 3.58%, respectively, which in contrast outperformed than the PCE obtained from P3HT:PC₆₁BM device (3.01%). The remarkably improved performance for P3HT:PC₆₁BM:2-DHP can be attributed to the enhanced short-circuit current density induced by the morphology optimization. Additionally, the devices fabricated with the solid additives (2-DHP and 2,4-DHP) exhibited improved air-stability due to the oxygen insensitivity of the functional groups present in the chosen additives. The pyridine and hydroxyl groups in 2-DHP and 2,4-DHP possibly form the intermolecular interactions with the photoactive components (P3HT/PC₆₁BM), contribute to the morphology optimization and subsequent PV performance enhancement in BHJ PSCs. It is believed that our findings can inspire and trigger further advanced research toward the design and development of stable and highly efficient BHJ PSCs by rationally choosing low-cost solid additives.]]> Mon 29 Jan 2024 18:04:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34261 Eucalyptus leaf extract (EL-RGO) was investigated, which was characterized with ultraviolet-visible spectroscopy (UV), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and Thermal gravimetric analysis (TG). Eucalyptus leaf extract also play both reducing and capping stabilizing agents prepared EL-RGO as shown a good stability and electrochemical properties. This approach could provide an alternative method to prepare EL-RGO in large-scale production. Moreover, the good electrochemical property and biocompatibility can be used in various applications.

It is also shown that for the former the bonding configuration facilitates an emergence of unquenched orbital angular momentum L along -K-M direction, which then lifts the spin degeneracy of the electronic states through the spin-orbit coupling (SOC) of electrons in Pb.
