Abstract This study investigates the photocatalytic activity of a novel Mn-doped Bi4O5Br2 material prepared via a facile synthesis process. The experimental and theoretical results confirm that Mn doping enhances the efficiency of NO removal over a Bi4O5Br2 catalyst under visible light irradiation. The SEM (scanning electron microscopy), BET (Brunauer-Emmet-Teller), XRD (X-ray diffraction) analyses show that neither the surface morphology nor the phase of the photocatalytic material changes afte...

Abstract Porous carbon nitride integrated with the cyano and hydroxyl functional groups are obtained through simple KCl assisted thermal treatment of urea. The existence of cyano and hydroxyl groups were confirmed through FTIR, NMR, and XPS characterizations. Easily removed KCl powders play a key role to produce a porous carbon nitride with cyano and hydroxyl groups. The DFT calculation was employed to estimate the band gap structure of the modified carbon nitride. It is shown that the cyano and...

Abstract Bi0 nanoparticles-loaded on Bi3+-doped ZnWO4 (Bi/ZBWO) nanorods are prepared by a two-step hydrothermal-solvothermal method. The electron paramagnetic resonance (EPR) spectroscopy results show the formation of oxygen vacancies resulted from Bi3+ doping in the Bi3+-doped ZnWO4 (ZBWO). The as-prepared samples are applied in photo-oxidation removal of NO under simulated sunlight and vis-light irradiation. Among the samples, Bi/ZBWO exhibits the best photocatalytic performance than pure ZWO...

Abstract Bi5O7I is a member of the bismuth oxyiodides family with unique layered structures, generating an internal electrostatic field to promote the separation and transfer of photogenerated charge carriers. To further enhance its visible-light photocatalytic activity, various strategies, including creating the heterojunction, forming the defects, and engineering the bandgap and composition, have been applied. Another promising strategy is to construct a heterostructured photocatalyst. Here, w...

TiO2 with exposed (001) facets/Bi4O5Br2 nanosheets heterojunction (TNS/BOB) was fabricated via hydrothermal and electrostatic self-assembly method, their photocatalytic activity for NO removal was evaluated under simulated solar light irradiation. Through optimizing the content of TNS nanosheets, it was observed that the photo-oxidative NO removal rate of 15% TNS/BOB was up to 54.3%, while that of single component TNS and BOB was only 31.1 and 37.7%, respectively. Through the capturing experimen...

La3+-Doped ZnWO4 nanorods were prepared via a hydrothermal method for the photocatalytic NO removal under simulated solar light irradiation. It was revealed by photocatalytic experiments that the 0.6% La3+-doped ZnWO4 nanorods exhibited the best photocatalytic activities for NO removal (46%) in comparison with other samples. The enhanced photocatalytic activity could be attributed to La3+ ion doping, which creates an abundance of oxygen vacancies (OVs) as confirmed by the electron paramagnetic r...

Abstract To fully utilize the solar light, photocatalyst with broad spectrum response from UV to near-infrared (NIR) is desirable. In this work, ternary mixed valent Bi2O4-Bi4O7-BiO2-x with rich oxygen vacancy has been synthesized through one-pot hydrothermal treatment of NaBiO3. The results showed that through adjusting the hydrothermal conditions, oxygen vacancy-rich Bi2O4-Bi4O7-BiO2-x nanocomposites with much higher efficiency than single or mixed bismuth oxides (Bi2O4, Bi4O7, BiO2-x and Bi4O...

Abstract As a direct Z -scheme photocatalyst, a two-dimensional/two-dimensional (2D/2D) Bi 2 O 2 CO 3 /Bi 4 O 5 Br 2 (BOC/BOB) heterostructure was fabricated by stacking the ultrathin nanosheets of Bi 2 O 2 CO 3 and Bi 4 O 5 Br 2 via a simple one-step hydrothermal synthesis process. The atomic force microscopy (AFM) and high-resolution transmission electron microscopy (HRTEM) results show that the heterostructure was successfully formed by coupling the ultrathin nanosheets of BOC and BOB. By opt...

Doping and novel metallic nanoparticles loading on the photocatalyst are two effective means to enhance its photocatalytic activity. In our study, Pd0/Pd2+-co-modified ZnWO4 nanorods were fabricated by a two-step hydrothermal process and room-temperature reduction method. The performance of the as-prepared samples was evaluated through the photocatalytic nitric oxide (NOx) removal under simulated solar and visible-light irradiation. Pd0/Pd2+-co-modified ZnWO4 nanorods present a significantly enh...

Highly exposed active facets and surface oxygen vacancies (OVs) are beneficial for the photocatalytic removal of various harmful organic compounds. In this study, uniform Zn2+-doped BiOI microspheres, assembled by ultrathin nanosheets with highly exposed {001} facets, with OVs were successfully synthesized for NO removal under visible light irradiation. The phase structure and chemical states are analyzed by means of X-ray diffraction and X-ray photoelectron spectroscopy, respectively. The trans...
