Synthesis of single-crystal-like TiO2 hierarchical spheres with exposed {101} and {111} facets via lysine-inspired method

Ultrathin g-C3N4 Nanosheet-Modified BiOCl Hierarchical Flower-Like Plate Heterostructure with Enhanced Photostability and Photocatalytic Performance

“…E VB = E CB + E g (2) where X, E e and E g represent the absolute electronegativity of the corresponding semiconductor, the energy of free electrons on the hydrogen scale (4.5 eV) and band gap of the corresponding semiconductor, respectively. The X values of BiOCl and g-C 3 N 4 are calculated to be 6.33 eV and 4.72 eV, respectively.…”

“…For this purpose, many studies have been devoted to developing modified traditional TiO 2 or TiO 2 -alternative photocatalysts for improving their photocatalytic performance [1][2][3][4][5]. As an important representative of BiOX (X = Cl, Br, I) species (p-type semiconductors), BiOCl has unique layered structure built by interlacing (Bi 2 O 2 ) slabs with double chlorine slabs, leading to the formation of self-built internal static electric fields.…”

Enhanced photocatalytic performance of SnS2 under visible light irradiation: strategies and future perspectives

“…As a photocatalyst, some characteristics of SnS 2 have become key for an excellent performance. These include low recombination and hole rates, 56–59 a high specific surface area, 60,61 high-reactivity facets, 62,63 and good stability. 64,65 Despite the confirmed photocatalytic performance of SnS 2 , there are still limitations that hinder its efficiency, such as a high recombination of electrons and holes, 66,67 and low specific surface area.…”
