Highly efficient photocatalytic hydrogen generation of g-C3N4-CdS sheets based on plasmon-enhanced triplet–triplet annihilation upconversion

Recent advances in materials for and applications of triplet–triplet annihilation-based upconversion

“…Fang et al hybridized a photocatalyst with plasmon-based TTA-UC nanoparticles. 11 By combining platinum and gold nanoparticles on TTA nanoparticles, the green-to-blue TTA efficiency was increased, and effective photocatalytic hydrogen production was achieved by incorporating it into g-C 3 N 4 -CdS sheets. In Fig.…”

“…These results imply that the high-energy photons obtained through the TTA-UC process and metal nanoparticles can significantly increase the photocatalytic hydrogen production. 11 Yu et al proposed upconversion micelles for red-to-cyan photon conversion by integrating with Cd 0.5 Zn 0.5 S. 21 By changing the concentration of Cd 0.5 Zn 0.5 S and the light irradiation strength, the optimal pathway of photocatalytic hydrogen production was found, which was able to produce approximately 2.3 mL of hydrogen after 5 hours of red light (629 nm) irradiation (2.4 mW cm −2 ). Here, NBPEA, a quaternary ammonium (Na 2 S, Na 2 SO 3 → Na 2 S 2 O 3 ) with excellent water solubility, was used as a cationic derivative to increase the efficiency of the photocatalyst.…”

The Sono-Photocatalytic Performance of PAN/g-C3N4/CdS Nanofibers Heterojunction

“…All samples present three obvious characteristic peaks at 2θ = 13.1°, 27.5°, and 17.1° that are ideally indexed to g-C 3 N 4 phase (001) and (002) planes (JCPDS-87-1526) [ 42 , 43 ] and PAN phase (111) planes [ 44 ], respectively. With the CdS nanoparticles deposition, the samples present three new and obvious characteristic peaks at 2θ = 26.5°, 43.7°, and 52.1° that are well attributed to CdS phase (111), (220) and (311) planes (JCPDS-80-0019) [ 45 ]. It was confirmed that the CdS were successfully introduced to PAN/C 3 N 4 and had formed a composite photocatalyst.…”

Two dimensional Ni2P/CdS photocatalyst for boosting hydrogen production under visible light irradiation

“…In addition, a d-spacing of 0.32 nm was clearly seen and attributed to the (110) plane of CdS. 31 Most importantly, the presence of the heterojunction between Ni 2 P and CdS was conrmed by Fig. 5.…”
