All-Solid Z-Scheme Bi–BiOCl/AgCl Heterojunction Microspheres for Improved Electron–Hole Separation and Enhanced Visible Light-Driven Photocatalytic Performance

“…In fact, the hydrogen production performance of BiOCl is not very ideal, as is shown in Figure c, and the photocatalytic BiOCl, Bi–BiOCl, and BiOCl/AgCl only show 45.6, 126.1, and 97.8 μmol h –1 g –1 , respectively. which has been revealed in the previous studies (Qian et al, 2017; Li et al, 2018; Li et al, 2019); − however, the hydrogen production rate of Bi–BiOCl/AgCl can reach 198.2 μmol h –1 g –1 , five times that of the original BiOCl, suggesting that photogenerated charges have the high utilization rate and excellent photocatalytic Bi–BiOCl/AgCl recycling hydrogen production capability.…”

Crystal Facet-Dependent Intrinsic Charge Separation on Well-Defined Bi 4 TaO 8 Cl Nanoplate for Efficient Photocatalytic Water Oxidation

“…Realizing spatial charge separation on photocatalysts is dependent on the adopted preparation processes for the construction of crystal facets with dissimilar surface work function [19,20]. The crystal facet-dependent charge separations have been reported on several photocatalysts, such as BiVO 4 , TiO 2 , BiOCl, SrTiO 3 , BaTaON, and NaTaO 3 [21][22][23][24][25][26]. Nevertheless, exploring wide-range visiblelight-active photocatalysts with excellent charge separation properties and deepening understandings of the relationship between spatial charge separation and coexposed crystal facets are needed for further enhancing intrinsic charge separation efficiency and promoting the development of photocatalysis.…”

Realization of Oriented and Nanoporous Bismuth Chalcogenide Layers via Topochemical Heteroepitaxy for Flexible Gas Sensors

“…Bismuth-based two-dimensional (2D) layered materials, such as bismuth chalcogenides [1,2], bismuth oxyhalides [3,4], and bismuth halides [5,6], are emerging eco-friendly functional materials that find wide applications in electronics, optoelectronics and energy conversion, and storage devices [7][8][9]. Bi 2 Se 3 possesses excellent electrical conductivity even under a high density of defects and dislocations, since its surface states are protected from scattering [10][11][12].…”
