2012年9月1日 · FTIR is a technique used to obtain information about the chemical bonding in a material. It is used to identify the elemental constituents of a material. The characteristic peaks exhibited by FTIR spectra of undoped and Cu doped ZnO nanoparticles are as shown in Fig. 7.

Here, Cu-doped SnO 2 that undergoes in situ reconstruction to form catalytically active Cu/Sn alloys was synthesized at cathodic potentials during CO 2 reduction reactions (CO 2 RR). The Cu-doped SnO 2 exhibited a remarkable formate Faradaic efficiency of over 90 % and maintained stability for 12 h.

The FTIR results indicated that intensity peaks of the CuSO4 are shaper as compared to TiO2, which are highly attached due to hydrophilic nature of the polyester after plasma treatment and ...

In this research, a series of copper-doped titanium dioxide (Cu-TiO2) photocatalysts were synthesized via three different methods of sonochemical, impregnation and physical mixing. Cu-TiO2 with...
