Nanoporous g-C3N4/MOF: high-performance photoinitiator for UV-curable coating

CdS/VS2 Heterostructured Nanoparticles as Efficient Visible‐Light‐Driven Photocatalysts for Boosting Hydrogen Evolution

“…It shows that the photocatalyst has the fastest electron hole transfer and separation rate and faster catalytic reaction rate. [44,51] In order to the transfer and separation of the photogenerated electron-hole pairs, the transient photocurrent density vs. time curves are carried out at the turn on or off the light condition. As shown in Figure 5c, CdS/VS 2 (0.2 wt.%) exhibits high photocurrent density due to its low electron-hole recombination rate, demonstrating that CdS/ VS 2 (0.2 wt.%) photocatalyst is effective to prevent the combination of the photogenerated electron-hole pairs.…”

“…[40][41] Constructing heterojunction has been proved to a particularly effectively protocol for inhibiting the photocorrosion and improving the separation of photogenerated electrons and holes Therefore, it is highly meaningful to explore whether construction of VS 2 /CdS heterojunction is beneficial for photocatalytic HER of CdS. [42][43][44] In this work, a novel CdS/VS 2 heterostructured photocatalyst was developed for the first time and performed efficient photocatalytic hydrogen evolution reaction under visible light(� 420 nm). The optimal CdS/VS 2 (0.2 wt.%) hybrid showed prominent photocatalytic HER activity, which is 16 times higher than the pristine CdS counterpart, even outperforming the 1 wt.% platinum-loaded CdS.…”

“…Moreover, the experimental results show that VS 2 has the better HER activity than MoS 2 [40–41] . Constructing heterojunction has been proved to a particularly effectively protocol for inhibiting the photocorrosion and improving the separation of photogenerated electrons and holes Therefore, it is highly meaningful to explore whether construction of VS 2 /CdS heterojunction is beneficial for photocatalytic HER of CdS [42–44] …”

Tunable Quantum Photoinitiators for Radical Photopolymerization

“…Hang et al studied the role of graphitic carbon-based nanoporous composites in developing UV photocurable coatings [ 62 ]. They fabricated graphene carbon nitride/metal organic framework (g-C 3 N 4 /MOF) composites with nanoscale porosity via a solvothermal approach.…”

“…The average particle size of the g-C 3 N 4 /MOF-5 composite structures was observed to be nearly 10–15 μm; the pores in these structures were 10–100 nm in diameter. UV–Vis diffuse reflectance spectroscopy recorded a substantially lower optical band gap for the as-synthesized composite, of 2.69 eV, which was significantly lower than the corresponding value for the MOF-5 material (3.86 eV) [ 62 ]. The composite was found to possess strong photocatalytic activity, which was evaluated in terms of the variation in curing time of a UV light-cured coating; nanoporous g-C 3 N 4 /MOF-5 composites were shown to shorten the curing time to 13 min from 20 min [ 62 ].…”
