Rational design of one inorganic-organic hybrid Z-scheme heterojunction for high-performance photocatalytic water splitting

Ultrafast carrier recombination in a BC6N/SnXY Z-scheme heterostructure for water splitting: insights from ground- and excited-state carrier dynamics

“…The strong coupling of the interlayer carriers is a prerequisite for determining a heterostructure as a Z-scheme heterostructure. 50,51 Therefore, the kinetic processes of excitons inside heterostructures are dealt with by means of the nonadiabatic molecular dynamics (NAMD). When the lifetime of interlayer electron-hole recombination is shorter than that of the carrier migration, this means that the photogenerated electrons on SnXY tend to couple with the holes in BC 6 N. 52 The lifetime of the corresponding process can be observed in Fig.…”

Tunability of Hybrid Silica Xerogels: Surface Chemistry and Porous Texture Based on the Aromatic Precursor

“…Organic-inorganic hybrid materials continue to arouse interest today because the synergy between both components bestows them with unique properties suitable for various applications [1][2][3][4]. Among these hybrid materials, organically modified silicates, or ORMOSILs, stand out for their diversity of morphologies, porous textures and surface chemistries, making them versatile candidates for use as coatings for materials [5][6][7], and as chemical membranes for optical fibre sensors [8][9][10].…”

Heterostructured Photocatalysts for Water Splitting and the Interfacial Charge Transfer

“…This rapid interlayer recombination suggests that the BP(5|9)/ SnSe 2 has excellent potential for direct Z-Scheme photocatalytic OWS. Lin et al analyzed the separation and recombination of carrier generation in the inorganic−organic hybrid heterojunction CdS/C 6 N 7 109. NAMD simulations show that more than 95% of the photoexcited electrons transfer within 20 ps, and about 80% of them recombine with holes at the VBM of CdS, while less than 15% undergo interlayer recombination, as shown in Figure…”
