Template-free preparation of carbon nitride hollow spheres with adjustable sizes for photocatalytic hydrogen generation

Critical role of hydrogen bonding between microcrystalline cellulose and g-C3N4 enables highly efficient photocatalysis

“…9 The characteristic peaks at 401.46 eV were attributed to the amino-functionalized functional groups containing H 2 (C–N–H) and the weakest peak at 404.43 eV pointed to π excitations. 10 As for MCC-0.05/CN, all the peaks shifting downward to a lower binding energy may indicate the formation of H-bonds after the introduction of MCC. 9 The hydroxy-rich MCC was likely to form extramolecular H-bonds with CN, as shown in Fig.…”

A Unique, Porous C3N4 Nanotube for Electrochemiluminescence with High Emission Intensity and Long-Term Stability: The Role of Calcination Atmosphere

“…The diameter and the thickness of nanotube was about 350 nM and 50 nM, respectively. The hollow tubular structure was maybe caused from the Ostwald Ripening phenomenon during the thermal polymerization process, while the pores on the surface probably attribute to the additional gas release in the heating process [ 25 , 26 ]. These hollow and porous structures generally contribute to expose considerable catalytic active sites and promote the electrolyte diffusion, thus improving the catalytic performance of the material [ 27 , 28 ].…”

A photocatalyst prepared by NiCo2O4/CNQD-modified carbon fabric heterojunction enhanced visible-light-driven photocatalytic degradation of methyl orange

“…9f, the signal peak with an intensity ratio of 1 : 2 : 2 : 1 corresponds to DMPO–˙OH, thus confirming the formation of ˙OH, and the photon generated under visible light irradiation could accelerate the transformation of ˙O 2− and ˙OH. 38,41…”

“…The free radical capture experiments were conducted with the quenching agent of IPA (a quencher of ˙OH), BQ (a quencher of ˙O2− ) and EDTA (a quencher of h + ). 36,37,41 Fig. 9d shows the photocatalytic impact of the quenching agents.…”
