• , Cl), Br (I). Dong et al. [88] reported the fabrication of boron-doped Bi3O4Cl ultrathin nanosheets via a solvothermal technique, which were found to have enhanced solar absorption and efficient electron–hole separation. The B atoms enhance the photocatalytic performance via (1) producing mid-gap

The selected-area electron diffraction (SAED) pattern shown in the inset of Figure 2a indicates that the MoO3 nanosheets are crystalline after exfoliation. Crystallinity and

• nanosheets by optical microscopy. Franckeite is one of the latest novel layered materials added to the 2D materials family and up to now very little is known about this material [15][16][17][18]. One of the special characteristics that triggered the interest of the community on franckeite is the fact that it

• ; ultrathin nanosheets; Introduction In the past two decades, dye-sensitized solar cells (DSCs) have received substantial attention from both academic and industrial communities as one of the most promising low-cost, high-efficiency third-generation photovoltaic devices [1][2]. A typical DSC consists of a
