Sharply increasing the visible photoreactivity of g-C3N4 by breaking the intralayered hydrogen bonds

Highly crystalline carbon nitride hollow spheres with enhanced photocatalytic performance

“…As shown in Fig. 3(b), the chemical shifts appear at 164.3 and 156.6 ppm in the NMR curve, which correspond to the C(e) atoms (C-N-H2) and C(i) atoms (C-N3), respectively [47]. These results demonstrate the existence of heptazine units in the CCNHS and CM-CN frameworks.…”

Isotype Heterojunction-Boosted CO2 Photoreduction to CO

“…As shown in Fig. 3a, b, the band absorption edges of MCN, ICN-3, and TCN originate from the π-π* electron transition upon irradiation [44,46]. ICN-3 exhibits approximately an averaged light-harvesting ability of MCN and TCN and a slight red shift in comparison with MCN (506 vs. 486 nm).…”

Ultrathin 2D/2D Graphdiyne/Bi2WO6 Heterojunction for Gas-Phase CO2 Photoreduction

“…Notably, the thickness of Bi 2 WO 6 NSs becomes thinner than that of the pristine counterpart, probably caused by the growth limiting effect of GDY NSs, which can also be confirmed by the decreased intensity and broadened X-ray diffraction (XRD) peak (Figure S3). The thinner layered morphology is beneficial to the charge transfer from the bulk to the surface of materials . Furthermore, the high-resolution transmission electron microscopic (HRTEM) image affirms that BiGDY-3 possesses an obvious 2D stacked layered structure with the intimate two-phase interfacial contact (Figure e).…”

“…The thinner layered morphology is beneficial to the charge transfer from the bulk to the surface of materials. 19 Furthermore, the high-resolution transmission electron microscopic (HRTEM) image affirms that BiGDY-3 possesses an obvious 2D stacked layered structure with the intimate two-phase interfacial contact (Figure 1e). The clear lattice spacing (d = 0.321 nm) is ascribed to the (131) facet of Bi 2 WO 6 , 20 while the amorphous region is attributed to GDY.…”
