Abstract:

Since 1998, the Au–O–Ti4+ sites of Au/Ti-based catalysts have been widely acceptedas the active sites for propene epoxidation with H2 and O2 at a relatively hightemperature, although they are limited by poor H2 efficiency.It was found that the Ti–OOH generation rate is higher on Au–O–Ti3+ than>2O2 and the Ti–OOH intermediate, even at a low temperature.

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.2000577

Abstract: has the advantage of broadband saturable absorption from the visible to the infrared bands. Herein, the two-dimensional material saturable absorber (SA) of the family was first applied experimentally in a wideband tunable passively Q-switched Yb-doped fiber laser. High-quality crystals were synthesized by the flux zone method. The SA with fewer layers was further prepared via a modified mechanical exfoliation procedure. Meanwhile, stable wavelength-tunable passive Q-switching pulse operation was obtained in a Yb-doped fiber ring cavity based on the SA, where the central wavelength can be continuously tuned from 1040.89 to 1092.85 nm. Results suggest that has wideband saturable absorption properties, and that the tunable pulse laser can provide a convenient and simple source for practical applications.

Effective regeneration of thermally deactivated commercial V-W-Ti catalysts

Xuesong SHANG, Jianrong LI, Xiaowei YU, Jinsheng CHEN, Chi HE

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1,   Pages 38-46 doi: 10.1007/s11705-011-1167-z

Abstract: An effective method for the regeneration of thermally deactivated commercial monolith SCR catalysts was investigated. Two types of regenerated solutions, namely NH Cl (1 mol/L) and dilute H SO (0.5 mol/L), were employed to treat the used catalyst. The effects of temperature and the regeneration process on the structural and textural properties of the catalysts were determined by X-ray diffraction, scanning electron microscopy, N adsorption/desorption, elemental analysis and Fourier transform infrared spectroscopy. The results suggest that the anatase phase of the used catalyst is maintained after exposure to high temperatures. Some of the catalytic activity was restored after regeneration. The catalyst regenerated by aqueous NH Cl had a higher activity than that of the catalyst treated by dilute H SO . The main reason is that the NH generated from the decomposition of NH Cl at high temperatures can be adsorbed onto the catalyst which promotes the reaction. The aggregated V O were partially re-dispersed during the regeneration process, and the intrinsic oxidation of ammonia with high concentrations of O is a factor that suppresses the catalytic activity.
