Low energy photocatalytic glycerol conversion to high valuable products via Bi2O3 polymorphs in the presence of H2O2

Clarifying solvent effect during photocatalytic glycerol conversion on TiO2/GQD as selective photocatalyst

“…After that, 30 mL of H 2 O 2 was added to the solution before irradiation started. An aliquot of 5 mL was taken and filtered every half hour for analysis 30 . Quantitative analysis of the variation in glycerol concentration and chemical species in the samples was done using gas chromatography-mass spectroscopy (GC–MS).…”

Non-noble-metal TiC-nanoparticle-promoted charge separation and photocatalytic degradation performance on Bi2O3 microrods: degradation pathway and mechanism investigation

“…19,20 As the simplest bismuth-based photocatalyst, bismuth oxide (Bi 2 O 3 ) is considered to be a promising visible-light photocatalyst owing to its excellent thermal stability, high refractive index and good photoconductive behaviour. 21,22 In addition, the hybridization of the Bi 6s and O 2p orbitals in Bi 2 O 3 makes the valence band (VB) move up, which is beneficial to the electron migration from the VB to the conduction band (CB), thus showing good photocatalytic mobility. 23 However, Bi 2 O 3 has the disadvantages of high complexation rate of photogenerated charges and limited visible-light absorbing ability, which hinder its photocatalysis applications.…”
