    Abstract Some oxide-based particulate photocatalyst sheets exhibit excellent activity during the water-splitting reaction. The replacement of oxide photocatalysts with narrow-bandgap photocatalysts based on nonoxides could provide the higher solar-to-hydrogen energy conversion efficiencies that are required for practical implementation. Unfortunately, the activity of nonoxide-based photocatalyst sheets is low in many cases, indicating the need for strategies to improve the quality of nonoxide photocatalysts and the charge transfer process. In this work, single-crystalline particulate SrTaO

  2. Artikel: Synergistic Effect of Hydrochloric Acid and Phytic Acid Doping on Polyaniline-Coupled g-C₃N₄ Nanosheets for Photocatalytic Cr(VI) Reduction and Dye Degradation

    Abstract In this study, graphitic carbon nitride (g-C₃N₄) nanosheets (CNns) were modified using polyaniline (PANI) codoped with an inorganic (hydrochloric acid, HCl) and an organic (phytic acid, PA) acid. Our results revealed that these samples exhibited extended visible-light absorption and a three-dimensional (3D) hierarchical structure with a large specific surface area. They also inhibited photoluminescence emission, reduced electrical resistance, and provided abundant free radicals, resulting in high photocatalytic performance. The PANI/g-C₃N₄ sample demonstrated outstanding photocatalytic activity of a Cr(VI) removal capacity of 4.76 mg·min–¹·gc–¹, which is the best record for the reduction of a 100 ppm K₂Cr₂O₇ solution. Moreover, g-C₃N₄ coupled with PANI monotonically doped with HCl or PA did not demonstrate increased activity, suggesting that the codoping of HCl and PA plays a significant role in enhancing the performance. The improved photocatalytic activity of PANI/g-C₃N₄ can be attributed to the interchain and intrachain doping of PA and HCl over PANI, respectively, to create a 3D connected network and synergistically increase the electrical conductivity. Therefore, new insights into g-C₃N₄ coupled with PANI and codoped by HCl and PA may have excellent potential for the design of g-C₃N₄-based compounds for efficient photocatalytic reactions.

    Abstract Metal nanoclusters (involving metals such as platinum) with a diameter smaller than 1 nm were deposited on the interlayer nanospace of KCa2 Nb3 O10 using the electrostatic attraction between a cationic metal complex (e.g., [Pt(NH3 )4 ]Cl2 ) and a negatively charged two-dimensional Ca2 Nb3 O10 (-) sheet, without the aid of any additional reagent. The material obtained possessed eight-fold greater photocatalytic activity for water splitting into H2 and O2 under band-gap irradiation than the previously reported analog using a RuO2 promoter. This study highlighted the superior functionality of Pt nanoclusters with diameters smaller than 1 nm for photocatalytic overall water splitting. This material shows the greatest efficiency among nanosheet-based photocatalysts reported to date.

  7. Artikel: Activation of a Pt-loaded Pb₂Ti₂O₅.₄F₁.₂ photocatalyst by alkaline chloride treatment for improved H₂ evolution under visible light

    Abstract Pb₂Ti₂O₅.₄F₁.₂ is a new photocatalyst that has recently been reported to function under visible light with suitable stability, albeit with insufficient photocatalytic activity. The present work demonstrates that the photocatalytic activity of Pb₂Ti₂O₅.₄F₁.₂ during visible-light-driven H₂ evolution is improved following post-treatment with alkaline chlorides. The photocatalytic activity of the post-treated Pb₂Ti₂O₅.₄F₁.₂ was found to be greatly affected by both the type of alkaline chloride and the treatment temperature. Among the alkaline chlorides examined, a eutectic NaCl–CsCl mixture (35 : 65 molar ratio) was found to be the most effective. The optimized material, further modified with a Pt cocatalyst using an in situ photodeposition method with a H₂PtCl₆ precursor, showed approximately 10 times higher activity than that of an untreated analogue. The optimally modified Pb₂Ti₂O₅.₄F₁.₂ was also found to outperform Ru-loaded, Rh-doped SrTiO₃, which is one of the most active metal oxide photocatalysts workable under visible light. Transient absorption spectroscopy indicated that the reactivity of photogenerated free and/or shallowly trapped electrons in the Pt-loaded, NaCl–CsCl-treated Pb₂Ti₂O₅.₄F₁.₂ with H₂O was higher than that in an analogue not treated with the NaCl–CsCl mixture. Based on various physicochemical analyses, it is evident that the NaCl–CsCl treatment creates ion-exchangeable alkaline-titanate species on the catalyst surface that undergo proton-exchange during the photodeposition of Pt, leading to improved affinity for H₂O. This effect explains the high activity of the NaCl–CsCl-treated Pb₂Ti₂O₅.₄F₁.₂ during H₂ evolution under visible light.

    Abstract Cobalt-based compounds, such as cobalt(II) hydroxide, are known to be good catalysts for water oxidation. Herein, we report that such cobalt species can also activate wide-band-gap semiconductors towards visible-light water oxidation. Rutile TiO2 powder, a well-known wide-band-gap semiconductor, was capable of harvesting visible light with wavelengths of up to 850 nm, and thus catalyzed water oxidation to produce molecular oxygen, when decorated with cobalt(II) hydroxide nanoclusters. To the best of our knowledge, this system constitutes the first example that a particulate photocatalytic material that is capable of water oxidation upon excitation by visible light can also operate at such long wavelengths, even when it is based on earth-abundant elements only.

    Abstract A high degree of cocatalyst dispersion and intimate contact with the photocatalyst are vital for improving the activity of narrow bandgap photocatalytic materials. In this work, the addition of a small number of Na ions to a Pt cocatalyst deposited on a semiconducting BaTaO₂N photocatalyst (with an absorption edge of 650 nm) enhanced photocatalytic H₂ evolution under visible light irradiation. The addition of Na ions to the Pt-loaded BaTaO₂N (Pt/BaTaO₂N) caused more efficient evolution of H₂ than Na-free Pt/BaTaO₂N during Z-scheme overall water splitting. These results should assist in the fabrication of photocatalysts modified with highly dispersed cocatalysts for efficient water splitting.
