Photocatalytic removal of M2+ (Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Ag+) over new catalyst CuCrO2

Synthesis of nanocrystalline Cu deficient CuCrO2 – a high figure of merit p-type transparent semiconductor

“…9,10 The material has also been investigated for its photocatalytic properties. 11,12 p-type conductive films are obtained through intentional doping of the trivalent metal site (Ca, Mg, Ni) [13][14][15] , as crystalline stoichiometric CuCrO 2 is typically highly resistive. 13,16 High conduc- tivity can be achieved with one claim of 220 Scm −1 14 , although this has been difficult to reproduce with other growth methods.…”

Atomic layer deposition of transparent semiconducting oxide CuCrO2 thin films

“…20,21,22,23,24,25 It should also be mentioned that besides the TCO applications, CuCrO2 has attracted attention for a range of other applications, ranging from catalysis 26,27,28 and sensors 29,30 to thermoelectrics, 31,32,33 photocatalysis and removal of various hazardous gases 34,35 metal cations. 36 There are many methods available for the preparation of CuCrO2 thin films and coatings, such as reactive sputtering deposition, 37,38 pulsed laser deposition, 39,40,41,42 chemical solution deposition, 43,44,45,46 and molecular beam epitaxy. 47 However, these techniques may not be vital for the depositions where a precise thickness control (of the order of sub-nanometer) over a large-area and/or nanostructured substrate is required.…”

Preparation, characterization and photocatalytic activity of a novel composite photocatalyst: Ceria-coated activated carbon

“…However, it also shows some disadvantages such as: formation of toxic by-products and deactivation of the photocatalysts, thus it cannot be long term utilized [7][8][9]. Consequently, there are considerable attentions on the development of alternative photocatalyst with improved photocatalytic activity or longer stability during prolonged application [10][11][12].…”
