Background: Monitoring of the chemical synthesis of black titanium. Objective: In this study, we prepared a black titanium nanomaterial by chemical reduction (NaBH4 treatment). Control of the black TiO2 nanomaterial synthesis followed by a thermal analysis from 100°C to 400°C under azote atmosphere is presented. We used a commercial dye, Reactive Bezactiv Yellow (RBY) degradation, to examine the photocatalytic activity of the black titanium. Method: The thermal analysis of WT and a mixture of treated TiO4 (WT+NaBH2) was examined by thermogravimetric analysis (TGA). Results: A deformation of the crystalline lattice is extended beyond the entire visible spectrum. The thermal property reveals that the black titanium is more stable than the white titanium, and BT indicated a more photocatalytic performance than WT. Conclusion: We have successfully synthesized black titanium via chemical reduction employing a synthesis of white titanium. The thermal analysis reveals that BT has a high resistance than WT that offers a promising opportunity for several photocatalytic applications.

The BiOCl microspheres photocatalyst was obtained by a one-step alcohol-heating method. The reactants were Bi(NO3)3•5H2O、TiCl3 and absolute ethanol, and the sample was synthesized at 100°C and calcined at 600°C. It then characterized by XRD, SEM, UV-vis DRS. The results showed that the sample was microspheres, having excellent photocatalytic activity that the sample could degradate more than 94% of RhB in 65 minites which is better than P25 under UV irradiation.

AbstractGlasses-free augmented reality is of great interest by fusing virtual 3D images naturally with physical world without the aid of any wearable equipment. Here we propose a large-scale spatial multiplexing holographic see-through combiner for full-color 3D display. The pixelated metagratings with varied orientation and spatial frequency discretely reconstruct the propagating lightfield. The irradiance pattern of each view is tailored to form super Gaussian distribution with minimized crosstalk. What’s more, spatial multiplexing holographic combiner with customized aperture size is adopted for the white balance of virtually displayed full-color 3D scene. In a 32-inch prototype, 16 views form a smooth parallax with a viewing angle of 47°. A high transmission (>75%) over the entire visible spectrum range is achieved. We demonstrated that the displayed virtual 3D scene not only preserved natural motion parallax, but also mixed well with the natural objects. The potential applications of this study include education, communication, product design, advertisement, and head-up display.
