Enhanced solar-light-driven photocatalytic activity of surfactant-assisted Sn4+-doped ZnO

ZnO–SnO2–Sn nanocomposite as photocatalyst in ultraviolet and visible light

“…A material with a tin content of 5% was used in the decomposition of rhodamine B. The significance of the presence of electrons on the decomposition process in visible light can be attributed to the presence of tin nanoparticles (Shanmugam et al 2021). The metals present on the surface of the catalyst act as electron traps, reducing the recombination of electrons A B…”

Facile one‐pot pyrolysis preparation of SnO2/g‐C3N4 composites for improved photocatalytic H2 production

“…The application of Sn-containing components in facilitating electron transfer and improving charge separation has been widely reported. [43][44][45][46][47][48][49][50] Tin dioxide (SnO 2 ) is an n-type metal oxide semiconductor with a band gap of 3.5 eV and has excellent electron transport characteristics, and has attracted extensive attention due to its nontoxicity, low cost and outstanding photoelectric properties. [51][52][53] The SnO 2 conduction band is located at a suitable position below the g-C 3 N 4 conduction band, which is convenient for forming a heterojunction structure by combining SnO 2 and g-C 3 N 4 .…”

“…It is thus anticipated that the use of electron transport materials in g‐C 3 N 4 photocatalysts will enhance the photocatalytic activity by reducing the recombination of photogenerated carriers. The application of Sn‐containing components in facilitating electron transfer and improving charge separation has been widely reported 43‐50 . Tin dioxide (SnO 2 ) is an n‐type metal oxide semiconductor with a band gap of 3.5 eV and has excellent electron transport characteristics, and has attracted extensive attention due to its nontoxicity, low cost and outstanding photoelectric properties 51‐53 .…”
