A nanocomposite photoelectrode made of 2.2 eV band gap copper tungstate (CuWO4) and multi-wall carbon nanotubes for solar-assisted water splitting

Photo-electron double regulated resistive switching memory behaviors of Ag/CuWO4/FTO device

“…Fig. 3 displays a typical UV-vis absorption spectrum of CuWO 4 nanoparticles; the onset of the absorption locates at about 500 nm, indicating that as-prepared CuWO 4 nanoparticles have good light absorption properties in the visible light region, which is consistent with the reported results in the previous work [24]. Fig.…”

“…All the peaks on it can be indexed to a pure phase CuWO 4 (JCPDF 72-0616), corresponding to a triclinic structure. We can see that the XRD profile matches very well with that in the reported work [22][23][24]. No other impurity peaks are detected.…”

Improved Charge Separation in WO3/CuWO4 Composite Photoanodes for Photoelectrochemical Water Oxidation

“…Copper tungstate (CuWO 4 ) has recently been recognized as a promising tungsten-based ternary oxide for PEC water oxidation [9,13,14,15,16,17,18,19,20]. It is an n-type semiconductor with a smaller band gap of 2.3 eV, corresponding to a theoretical photocurrent density (J max ) of 10.7 mA/cm 2 [18,21,22].…”

Taguchi method assisted optimization of electrochemical synthesis and structural characterization of copper tungstate nanoparticles

“…Copper tungstate has attracted substantial interest during recent years, because this material could be used in various important areas of science and technology such as scintillation detectors, optical fibers, photoanodes, laser host, sensors, photoelectrolysis electrodes, and positive electrode preparation for lithium based rechargeable batteries [1][2][3][4][5][6][7][8]. Up to now several researches about the crystal growth [9,10], photoelectrochemical performance [10], electrochemical, optical, electrical, magnetic, and ferroelectric behaviors [1,5,[11][12][13][14][15] of the copper tungstate have been published.…”
