A novel Bi-based oxychloride CdBiO2Cl: Crystal structure, electronic structure and photocatalytic activity

ABiO2X (A = Cd, Ca, Sr, Ba, Pb; X = halogen) Sillen X1 Series: Polymorphism Versus Optical Properties

“…For these three materials, no correlation between the electronic structure and the optical properties was analyzed yet, therefore the effect of A and X on the excitation and emission energies remains unexplored. In addition, due to the existence of photocatalytic activities for BiOCl, CdBiO 2 Cl and PbBiO 2 Cl/Br, − the rationalization of their optical properties (presence of radiative recombination) under UV illumination in the extended ABiO 2 X series appears relevant. − This aspect is of fundamental interest due to the duality between the needs for efficient electron–hole pairs separation upon photoexcitation for photocatalysis (PC), while enhanced radiative recombination is desired for light emission.…”

Sn2SiS4, synthesis, structure, optical and electronic properties

“…Sn 2 SiS 4 possesses a three-dimensional framework built from these SnS 6 polyhedra and the SiS 4 tetrahedra and an indirect band gap of 2.00 eV, lying in the visible range. Furthermore, stimulated by the result that many compounds containing cations with electron lone pair (such as Bi 3+ ) demonstrate excellent photocatalytic activities [17][18][19][20] decomposition of Rhodamine B (RhB) under visible light irradiation (k > 420 nm) than C 3 N 4 does. The corresponding photocatalytic mechanism was also investigated.…”

Fast fabrication of Co3O4 and CuO/BiVO4 composite photocatalysts with high crystallinity and enhanced photocatalytic activity via ultrasound irradiation

“…Recently, a great number of novel semiconductor photocatalysts with visible light response have been developed, such as BiOI [9,12], Ag-AgI/Al 2 O 3 [8], g-C 3 N 4 [13], Cd 2 SnO 4 [14], LaNiO 3 [15], CdBiO 2 Cl [16], etc. They all exhibit certain absorption ability in the visible light range.…”
