Synthesis and photocatalytic activity of TiO2@CdS and CdS@TiO2 double-shelled hollow spheres

Facile synthesis of CdS@TiO2 core–shell nanorods with controllable shell thickness and enhanced photocatalytic activity under visible light irradiation

“…CdS@TiO 2 nanocomposites were synthesized by a modified method [50,52] After being stirred for 1 h at room temperature, the mixture was washed with ethanol several times and dried at 80°C overnight. Finally, the as-prepared samples were calcined at 200°C for 3 h to improve the crystallinity and remove organic residues in TiO 2 .…”

Low-temperature synthesis of alkalis doped TiO2 photocatalysts and their photocatalytic performance for degradation of methyl orange

“…Titanium dioxide (TiO 2 ) is a well-known semiconductor with a broad band gap, which has attracted much attention because of their outstanding chemical and thermal stability, high refractive index, great ultraviolet absorptivity, and resistance to photocorrosion [1][2][3][4][5][6]. Some potential applications of TiO 2 have been developed in various fields, including photocatalytic water splitting, environmental purification, self-cleaning and microorganism photolysis [1][2][3][4][5][6][7][8][9].…”

“…Some potential applications of TiO 2 have been developed in various fields, including photocatalytic water splitting, environmental purification, self-cleaning and microorganism photolysis [1][2][3][4][5][6][7][8][9]. There are three polymorphs of TiO 2 existing naturally: rutile, anatase and brookite [10].…”

Facile synthesis of SiO2@TiO2 crystallite photocatalysts with enhanced interaction level and high light absorption efficiency

“…Moreover, TiO 2 absorbs UV light that is the tiny portion of solar spectrum but has meager response to visible light due to a wide band gap of TiO 2 [6,7]. Fortunately, many novel approaches like doping with impurities [8][9][10], noble metal deposition [11,12], sensitizing with narrow band gap absorption materials [13,14] and hydrogenation process [15,16] have been found to be effective in enabling visible light absorption, while several inventive techniques such as heterostructuring with other semiconductors [17,18], integrating with carbon nanostructures [19,20], designing with exposed reactive facets [12,21] and hierarchical morphologies [22,23] have been developed to improve structural stability and charge carrier separation kinetics.…”
