In this work, Cu-doped NaFe0.5Co0.5O2 was easily prepared by a one-step solid-state reaction and studied the effect of copper salt precursors including CuCl2 and Cu(OAc)2 on the structure and electrochemical properties. XRD patterns of the synthesized materials all exhibited diffraction peaks of...
When integrated with anthocyanin dye, the DSSC featuring 0.075 M Cu-doped TiO 2 demonstrated a notable enhancement in photocurrent density, increasing from 5.8 to 7.6 mA cm 2 , while the power conversion efficiency (PCE) improved from 1.53% to 2.61%. This enhancement is attributed to the ...
Nanometer Cu-doped CeO2 (nano@Cu–CeO2) was synthesized by the method of precipitation. All catalysts were evaluated for the catalytic oxidation of CO, and the 3D@Cu–CeO2 catalyst exhibited the highest catalytic activity (complete conversion temperature T100 = 50 °C), which can be ...
Hierarchical 3D CoS nanosheet films are first synthesized by hydrothermal reaction and then converted to Cu-doped CoS nanoporous nanosheets through a cation exchange process. The Cu doping into CoS nanosheets leads to favorable a 3D porous structure, which could improve the electron-transfer capability...
To improve the thermal stability and the SET speed, the Cu doping has been performed because it can affect the crystallization temperature and contributes to a better SET speed [[16], [17], [18]]. However, electrical properties of Cu-doped Ge8Sb2Te11 have not been reported yet. Cu-doped...
