Download scientific diagram | FTIR spectra of H 2 O 2 (top) and pure H 2 O (bottom) and the variations in the difference spectra of H 2 O 2 after exposure to H atoms for up to 10 min at 15 K...

Bruker Tensor 37 FTIR: Instrument resolution: 2.0 cm-1: IR source: Silicon carbide glow bar: Aperture: 4 mm: Beam splitter: Broadband potassium bromide (KBr) Detector: DLTGS at room temperature: Scanner velocity: 10 kHz: Phase correction: Mertz: Interferogram zero fill: 4x: Spectral interval after zero fill: 0.4823 cm-1: Spectral range: 7800 to ...

1999年5月1日 · A simple and rapid method to detect hydrogen peroxide was developed. The FTIR peak of hydrogen peroxide was used for this purpose. A peak was observed at 669.18 cm −1 on NaCl window and another at 418.48 cm −1 on KBr window.

The potential of CeO2 as an epoxidation catalyst is studied for the reaction of propylene with hydrogen peroxide (H2O2) by Fourier transform infrared (FTIR) spectroscopy and temperature...

2020年5月5日 · Using fine characterization methods, such as soft XANES, XPS, FTIR, and CV, we show that each of our samples have targeted and desired functional groups (etheric ring, carboxyl and quinone).

Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here. Notice: Concentration information is not available for ...

2021年5月15日 · Artificial photocatalysis holds great promise for the production of cheap and clean H 2 O 2. Therefore, it is emerging interest to develop metal-free photocatalysts due to their adjustable band gap, wide spectral response range and cheap.

2015年8月6日 · The adsorption of water and deuterium oxide on TiO2 surfaces was investigated in the dark as well as under UV(A) irradiation using in situ ATR-FTIR spectroscopy under oxygen and oxygen free conditions. Adsorption of H2O–D2O mixtures revealed an isotopic exchange reaction occurring onto the surface of TiO2 in

In this review, an overview of the main contributions that have been determined, starting from IR absorption spectroscopy studies of catalytic systems for H 2 O 2 direct synthesis, is given. Which kind of information can be extracted from IR data?

2024年10月25日 · Here we show a B-doped g-C 3 N 4 (BCN) tailored with coordinatively unsaturated FeOOH and CoO x clusters for H 2 O 2 photosynthesis from water and oxygen without sacrificial agents.
