3D printed SrNbO₂N photocatalyst for degradation of organic pollutants in water

Abstract

Organic pollutants in water are a major concern for the environment and human health, and require urgent attention. Here, we developed for the first time monolithic structures by 3D printing...

A scalable neural network architecture for self-supervised tomographic image reconstruction

“…120 line scans). XRD-CT measurements were performed at beamline ID15A of the ESRF using a 3D printed SrNbO2N photocatalyst 52 and a 100 keV monochromatic X-ray beam focused to have a spot size of ca. 40 × 20 mm (horizontal × vertical).…”

“…First, we compare the results obtained from SD2Iu and the other methods using an experimental XRD-CT dataset acquired from a 3D printed SrNbO2N photocatalyst used for degradation of organic pollutants in water. 52 The original sinograms of this dataset had 300 projections and 331 translation steps (the image size is then 331 × 331). The image reconstructed by CGLS with the full 300 projections is considered as the ground truth image when calculating the metrics shown in Table 3 while the reconstructed images using the various methods are presented in Fig.…”

BaLa5V2O3N7: a novel anti-perovskite oxynitride for electrode applications

“…Transition metal oxynitrides have gained widespread attention for their unique properties, including dielectric and optical properties, ionic conductivity, and catalytic activity, and show special photocatalyst potential for the splitting of water [1][2][3][4] In particular, some oxynitrides based on Ta, Ti and Nb can be used as visible-driven photocatalysts, benefiting from their narrow band gaps, such as ABO 2 N (A = Ca, Sr, Ba, rare earth element; B = Ta, Nb, Ti), 5,6 MNON 2 (M = rare earth element; N = Ta, Nb), 7,8 Ca 3 Nb 2 N 2 O 5 . 9 In addition, (oxy)nitrides also display exceptional qualities in substances with high dielectric constants, such as CaTiN 2 (e r B 2500), 10 SrTaO 2 N(e r B 2900) and BaTaO 2 N (e r B 4900), 11 which are significant for energy storage and microelectronic capacitor functionalities.…”
