In 2019,Journal of Physical Chemistry C included an article by Xu, Xing; Lai, Lei; Jiang, Jiahong; He, Zhiqiao; Song, Shuang. Recommanded Product: 2,6-Diaminopyridine. The article was titled 《C,N-Codoped TiO2 with a Nitrogen-Doped Carbon Coating Derived from 2,6-Diaminopyridine for Visible Light-Induced Photocatalytic Hydrogen Evolution》. The information in the text is summarized as follows:
Nitrogen-doped carbon-wrapped C,N-codoped TiO2 (CN@C,N-TiO2) was successfully prepared using a facile and efficient method involving hydrolysis and calcination under Ar using tetra-Bu titanate and 2,6-diaminopyridine as the precursors. XPS and valence band XPS measurements reveal the successful codoping of interstitial carbon and nitrogen into TiO2, which leads to a visible-light absorption of up to ∼550 nm in the UV-vis diffuse reflectance spectra. Raman spectra and high-resolution TEM results show that N-doped carbon exists on the surface of C,N-TiO2, which gives rise to the efficient separation of photoexcited charge carriers, as determined by photoluminescence and electrochem. impedance spectroscopy. Benefiting from the combined effects of a surface-coated N-doped carbon layer and C,N-codoping, the photocatalyst calcined at 450° exhibits remarkable visible-light activity toward the hydrogen evolution reaction in the water splitting process with a H2 production rate of 833.2 μmol h-1 g-1 under 94 mW cm-2 visible-light illumination (λ > 420 nm). Moreover, the representative CN@C,N-TiO2 sample can maintain its activity for at least 40 h. After reading the article, we found that the author used 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 2,6-Diaminopyridine)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Recommanded Product: 2,6-Diaminopyridine
