Study of the electronic structure and photocatalytic activity of the BiOCl photocatalyst

Bismuth oxybromide promoted detoxification of cylindrospermopsin under UV and visible light illumination

“…Among them, n is determined by the type of optical transition of a semiconductor (n = 1 for direct transition and n = 4 for indirect transition). The value of n is 4 for BiOBr and 1 for TiO 2 [40]. The E g can be thus estimated from a plot of (˛h ) n/2 versus photon energy (h ).…”

Indirect-Direct Band Transformation of Few-Layer BiOCl under Biaxial Strain

“…[8][9][10][11] And to date, the thinnest ultrathin BiOCl nanosheet was synthesized with a thickness of 2.7 nm, which consisted of about four…”

Preparation of dielectric Bi4-xLaxTi3O12 (x~2) from K2La2Ti3O10 via exfoliation and restacking routes

“…2(b))으로 이동하는 것을 미루어 보아 층간 격자가 감소하게 되는데 이는 층간 내부 공간의 수소화 에 의한 것이고, c축의 길이가 ~2 Å 감소한 것을 확인 하였다. 수소화된 H 2 La 2 Ti 3 O 10 층상물질은 EA와 같은 유기아민을 가지고 이온교환반응을 통한 층간 삽입을 통 해 층 사이의 반데르발스힘을 줄임으로써 박리화가 가능 하다 [17] (Fig. 1).…”
