Interplay of Orbital and Relativistic Effects in Bismuth Oxyhalides: BiOF, BiOCl, BiOBr, and BiOI

Year: 2016

Type: article

Abstract: T he optoelectronic properties of bismuth oxyhalides have led to their utility in applications such as pigments in the cosmetics industry, 1,2 pharmaceuticals, 3,4 phosphors, 5 gas sensors, 6 and catalysis.7,8 Over the past decade, interest in this family of materials has rapidly increased, fuelled by reports of their excellent photocatalytic activity.[9][10][11][12][13][14][15][16] They have been studied as stand-alone photocatalysts, 9,10,17 quaternary alloys, 18,19 and interfaced with other photocatalytically active materials.[20][21][22] To date, however, an understanding of the chemical trends underpinning these successes is lacking.The BiOX series, shown in Figure 1, crystallize in the tetragonal Matlockite structure, 23,24 which can be considered
