A simple synthetic protocol for N-doped yellow TiO2 (N-TiO2) hollow spheres as an efficient visible-light-active photocatalyst using aqueous titanium peroxocarbonate complex (TPCC) solution as precursor and NH4OH was developed. In the developed strategy, the ammonium ion of TPCC and NH4OH acts as nitrogen source and structure-directing agent. The synthesized N-TiO2 hollow spheres were capable of promoting the synthesis of active esters ArCO2R [Ar = Et, 4-ClC6H4, 2-furyl, etc.; R = 2,5-dioxopyrrolidin-1-yl, 1,3-dioxoisoindolin-2-yl] of N-hydroxyimide and alc. through simultaneous selective oxidation of alc. to aldehyde followed by cross-dehydrogenative coupling (CDC) under ambient conditions upon irradiation of visible light. It was possible to develop a novel and cost-effective one-pot strategy for the synthesis of important esters and amides on gram scale using the developed strategy. The catalytic activity of N-TiO2 hollow spheres was much superior to that of other reported N-TiO2 samples as well as TiO2 with varying morphol. In addition to this study using 3-Pyridinemethanol, there are many other studies that have used 3-Pyridinemethanol(cas: 100-55-0Safety of 3-Pyridinemethanol) was used in this study.
3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Safety of 3-Pyridinemethanol
