MoS2 Nanoflower-Deposited g-C3N4 Nanosheet 2D/2D Heterojunction for Efficient Photo/Electrocatalytic Hydrogen Evolution

“…To achieve the maximum light harvesting and surface reactions, numerous strategies have been adopted, such as heteroatomic doping, heterostructure formation, , and modification of the thickness of g-C 3 N 4 nanosheets . Among these, heterostructure formation plays a vital role in advancing the field of photocatalysis. − Heterostructures showed effective electron–hole pair separation, prolonged light absorption, and synergistic effects that boost the catalytic activity of the materials. − In this regard, we have fabricated a Z-scheme MoS 2 /g-C 3 N 4 heterostructure that aids in suppressing the natural back reaction (e–h+ pair recombination), enhances the conductivity, and increases the catalytically active sites of g-C 3 N 4 for HER. , Therefore, MoS 2 /g-C 3 N 4 heterostructured catalytic systems can accelerate the HER efficiency through Z-scheme band alignment of their band structures, which eases out the transfer of electrons through interface electron channels . The interfacial layered engineering is feasible in a MoS 2 /g-C 3 N 4 system owing to the analogous layered structure that subdues the lattice mismatch between them by forming a homogeneous 2D/2D nanohybrid through the planar growth of MoS 2 layers over g-C 3 N 4 , Therefore, with the aim of exploiting synergistic effects between these two semiconductors, herein, we have fabricated MoS 2 /g-C 3 N 4 heterostructured catalysts for determining their excellence toward PC, EC, and PEC water splitting.…”

Insights from experiment and machine learning for enhanced TiO2 coated glazing for photocatalytic NOx remediation

“…On the other hand, the average performance of our materials is notably lower than that of other TiO 2 -based materials used for NO x removal, such as Cristal ACTiV™ PC-S7. 67 TiO 2 coatings produced using APCVD differ from photocatalytic materials that incorporate TiO 2 nanopowder powder; they have often a lower surface area and therefore less active, but can maintain high transparency and can be significantly more durable to abrasion lending themselves to applications for self-cleaning windows.…”
