Enhanced photocatalytic H2 production over dual-cocatalyst-modified g-C3N4 heterojunctions

Single Au Atoms Anchored on Amino‐Group‐Enriched Graphitic Carbon Nitride for Photocatalytic CO2 Reduction

“…The XRD pattern of U‐ACN in Figure S1 in the Supporting Information only shows the peaks of graphitic carbon nitride, whereas the peaks of Au nanoparticles at 38.1 and 44.4° are found in Au/graphitic carbon nitride (P‐ACN) prepared by photoreduction of HAuCl 3 in the presence of graphitic carbon nitride . The HAADF‐STEM image (Figure b and Figure S2 in the Supporting Information) of U‐ACN shows that Au with a size below 5 Å (light spots) is stably anchored on the CN substrate, even under the irradiation of the high‐energy electron beam.…”

In situ construction of protonated g-C3N4/Ti3C2 MXene Schottky heterojunctions for efficient photocatalytic hydrogen production

“…Protonation (i.e. acid pretreatment) is a functionalizing approach that can convert the negative charges on the surface of g-C3N4 into positive charges and adjust its electronic bandgap and ionic conductivity, thus improving its hydrogen generation performance [26][27][28][29][30][31]. In addition to the optimization of g-C3N4 alone, the fabrication of composite systems is also a common method to enhance photocatalytic capacity [32][33][34][35][36][37].…”

Synthesis of a well-dispersed CaFe2O4/g-C3N4/CNT composite towards the degradation of toxic water pollutants under visible light

“…In this mode, the charge separation of photogenerated electron-hole pairs can be drastically enhanced and the recombination rate can be minimized, thus improving the photocatalytic ability of the CaFe 2 O 4 /g-C 3 N 4 /CNT composite. [34][35][36][37][38][39][40] The possible photocatalytic mechanism for the photodegradation of Cr(VI) and TC as well as hydrogen generation using the ternary CaFe 2 O 4 /g-C 3 N 4 /CNT composite under visible light irradiation is proposed in Fig. S1.…”
