In this study, unique hybrid structures were constructed between a Ce-based metal-organic framework (Ce-MOF) and graphitic carbon nitride (g-C3N4) materials.

We present a comprehensive theoretical study of the structure and NMR parameters of a large number of triazine and heptazine based structure proposals for g-C 3 N 4 in different condensation states. This approach includes a detailed investigation of cyclic melon which tends toward the formation of densely packed hydrogen bonded meshes.

A new strategy is reported here to synthesize both nitrogen deficient and protonated graphitic carbon nitride (g-C3N4) nanosheets by the conjoint use of NH4Cl as a dynamic gas template together...

2025年3月1日 · To demonstrate the introduction of methyl groups in the formation of Q-PHI phase, solid-state 13 C nuclear magnetic resonance (NMR) spectra of CN and modified g-C 3 N 4 were recorded. In the 13 C NMR spectrum of CN ( Fig. 4 b), two strong peaks at 163.1 and 154.5 ppm were attributed to the C1 and C2 carbon species in the heptazine ring ...

2019年12月15日 · Herein, a surface-modified g-C 3 N 4 was synthesized by the co-condensation of urea + thiourea and 2-methyl imidazole. Physicochemical characterizations reveal that O and C are co-doped, as evident by the XPS and solid-state NMR spectroscopy.

2017年5月22日 · In this study, we present that solid-state NMR (SSNMR) analysis for ¹³C- and ¹⁵N-labeled g-C3N4 prepared from urea offers an unparalleled structural view for heterogeneous in-plane structure of...

2007年9月13日 · We present a comprehensive theoretical study of the structure and NMR parameters of a large number of triazine and heptazine based structure proposals for g-C3N4 in different condensation states. This approach includes a detailed investigation of cyclic melon which tends toward the formation of dens …

2017年5月22日 · In this study, we present that solid-state NMR (SSNMR) analysis for 13 C- and 15 N-labeled g-C 3 N 4 prepared from urea offers an unparalleled structural view for the heterogeneous in-plane structure of g-C 3 N 4 and most likely for its moieties. We revealed that urea was successfully assembled in melem oligomers, which include extended ...

2016年5月11日 · With the goal to accomplish a molecularly defined Pd-based heterogeneous C–C bond forming catalyst, highly ordered mesoporous nitrogen-rich carbon nitride (MCN) polymers with extended three-dimensional π-conjugation have been used as solid supports.

2023年4月20日 · In this work, we propose a strategy to enhance the ferromagnetism of 2D graphite carbon nitride (g-C 3 N 4), which is facilitating the short-range exchange interaction by introducing in-planar...
