Wavelength dependent luminescence decay kinetics in ‘quantum-confined’ g-C₃N₄ nanosheets exhibiting high photocatalytic efficiency upon plasmonic coupling

Abstract

Serendipitous observations offer newer insights into materials properties. Here we describe the g-C3N4 nanosheets exhibiting remarkably blue-shifted photoluminescence within the 390-580 nm range centring at 425 nm which matches more...

Carbon Nitride‐Based Ruthenium Single Atom Photocatalyst for CO2 Reduction to Methanol

“…Consequently, RuSA-mC 3 N 4 can provide more charge carriers for the photocatalytic reduction of CO 2 in comparison to C 3 N 4 . [52,53] A possible schematic representation of photocatalysis mechanism over RuSA-mC 3 N 4 surface under visible light irradiation is shown in Figure 5.…”

Developing extended visible light responsive polymeric carbon nitrides for photocatalytic and photoelectrocatalytic applications

“…[1][2][3][4][5] Some of the key factors determining the photoactivity of CN materials are their structural properties (including morphology and specific surface area) and their optical and electronic properties (such as band gap, electronic band positions, and charge separation under illumination). [6][7][8][9][10][11] For heterogeneous photocatalysis, the CN powders must also have good dispersibility in water, which is both the dispersant and the reactant in the hydrogen evolution reaction (HER); an additional pivotal requirement is the availability of free sites favoring the anchoring of co-catalysts. 12,13 As for photoelectronic devices, the precursors should be amenable to uniform casting and must remain bound to the substrate during the ensuing thermal polymerization.…”

Light-Induced Hypoxia in Carbon Quantum Dots and Ultrahigh Photocatalytic Efficiency

“…The PE-CQDs were used as photocatalysts for the controlled oxidation of benzylamine (BA) and its derivatives to the corresponding imines by using the large number of O 2 molecules present on the PE-CQDs (Note S4) as the oxidant. The development of amine to imine transformation methodologies that are mild and green has gained attention because of their use in functional organic and medicinal compounds. , Among these, photocatalytic oxidation is attractive due to its energy efficiency, leading to the development of many efficient photocatalysts. − …”
