几篇多孔C3N4合集
感觉C3N4很火,做的都是多孔,却感觉越发越高了。
Here we report a new and simple synthetic
pathway to form ordered, hollow carbon nitride structures,
using a cyanuric acid−melamine (CM) complex in ethanol
as a starting product. A detailed analysis of the optical and
photocatalytic properties shows that optimum hollow
carbon nitride structures are formed after 8 h of
condensation. For this condensation time, we find a
significantly reduced fluorescence intensity and lifetime,
indicating the formation of new, nonradiative deactivation
pathways, probably involving charge-transfer processes.
Enhanced charge transfer is seen as well from a drastic
increase of the photocatalytic activity in the degradation of
rhodamine B dye, which is shown to proceed via
photoinduced hole transfer. Moreover, we show that
various CM morphologies can be obtained using different
solvents, which leads to diverse ordered carbon nitride
architectures. In all cases, the CM-C3N4 structures
exhibited superior photocatalytic activity compared to
the bulk material. The utilization of CM hydrogen-bonded
complexes opens new opportunities for the significant
improvement of carbon nitride synthesis, structure, and
optical properties toward an efficient photoactive material
for catalysis.
