Self-assembled 3D BiOCl hierarchitectures: tunable synthesis and characterization

Constrained growth of ultrasmall BiOCl nanodiscs with a low percentage of exposed {001} facets and their enhanced photoreactivity under visible light irradiation

“…During the past few years, an exponential growth of efforts has been made to prepare BiOCl crystals with controllable size and morphology. Since the first report on the solvothermal preparation of BiOCl crystals in early 2002 [14], various strategies have been substantially developed [15][16][17][18][19][20]. Recently, a few attempts on the crystal facet engineering of BiOCl nanocrystals have been made as well.…”

“…A basic lone pair of electrons from the nitrogen atom competes with Cl -in the formation process of BiOCl, influencing the ultimate shape of the BiOCl crystals. Ma et al [22] reported the preparation of ultrathin BiOCl nanoflakes (around 18 nm) through a ionothermal synthesis technique under the structural direction of 1-hexadecyl-3-methylimidazolium chloride ([C 16 Mim]Cl). [C 16 Mim] + cations, which is preferably adsorbed on the ab plane of BiOCl, may inhibit the growth in [001] direction of BiOCl.…”

Surfactant-assisted growth and optical properties of ZnO hexagonal bilayer disk-like microstructures

“…Considerable effort has been devoted to the morphology-controllable synthesis of ZnO [3]. In our previous works, we reported the control synthesis of semiconductor metal oxide using different methods [4][5][6][7][8][9][10][11][12]. One of the most promising methods is a biomimetic strategy that uses surfactants or polymers as the structuredirecting agent to control the nucleation, growth, and alignment of crystals [3].…”

Enhanced Photo-induced Charge Separation and Simulated Solar Photocatalytic Activity of α-Fe2O3/BiOCl Prepared In-situ

“…Among the diverse photocatalytic materials, BiOCl is mostly studied because of its unique layered structure and high chemical stability, a great deal of research has been conducted to study its photocatalytic performance under UV irradiation (4,5). The tetragonal bipyramidal crystal geometry of BiOCl can be usually flattened into flakes or platelets with a high aspect ratio.…”
