In the existing study, an attempt has been made to develop scratch resistant polycarbonate (PC) nanocomposites using inorganic ZnO nanoparticles doped with copper (ZnCuO). The ZnCuO nanoparticles were synthesized using co‐precipitation method and modified using phosphoric acid ethyl hexyl ester (PAEH). The size range of nanoparticles was confirmed to be around 55–75 nm using AFM. TGA, FTIR, and NMR confirmed modification of nanoparticles and XRD approved of size reduction due to doping. PC/ZnCuO nanocomposites (PCNC) with a loading of 1%, 3% and 5% by weight were prepared by melt extrusion and an evaluation of thermal, thermo‐mechanical, and tribological properties were carried out. The dispersion study using FE‐SEM images revealed the presence of aggregates. Thermal analyses using TGA and DSC indicated a decrement in stability for PCNC. The PCNC was found to exhibit better storage modulus with an enhancement of 23% with a 3 wt% loadings of nanoparticles as compared to pure PC. The tribological study of PCNC indicated a favorable decrement of a coefficient of friction by nearly 14% in the case of 3% PCNC. POLYM.

“…The green band can be attributed to oxygen vacancies and intrinsic defects. The green emission observed is also owing to impurity levels that correspond to the singly ionized oxygen vacancy in ZnO [16][17].The visible emissions at 620 nm and 675 nm were mainly caused by singly ionized oxygen vacancies, which occur in recombining photogenerated holes with the electrons of the oxygen vacancies [8,[13][14]. The visible emission is caused by Zn and O vacancies.…”

“…Doping ZnO with transition metal elements such as Ni, Co, Al, and Cu has been demonstrated to be an efficient way of modifying its capabilities, including electrical and magnetic properties. Cu doped ZnO has recently shown improvement in necessary features such as electrical, magnetic, and photocatalytic performance and gas sensing properties [8]. To the best of our knowledge, no research has been reported for Pr and Cu co-doping in ZnO nanoparticles by the co-precipitation method.…”

At room temperature, zinc oxide (ZnO) nanoparticles co-doped with praseodymium (Pr) and copper (Cu) using a low-cost chemical co-precipitation method. As a capping agent, polyvinylpyrrolidone (PVP) was used for synthesizing the nanosamples, and a pH of 9 was maintained. The synthesis of nanosamples was then characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and photoluminescence (PL). X-ray diffraction studies revealed the wurtzite hexagonal structure of ZnO, and no impurity peaks were found. The particle size obtained from XRD studies was 32 to 46 nm and is well supported by TEM. SEM micrographs demonstrated the surface morphology of the samples. With Cu dopant concentration, Pr-doped ZnO nanosamples exhibited enhanced luminescence properties.

Telah dilakukan penelitian tentang kinetika fotodegradasi remazol yellow dengan menggunakan ZnO dan ZnO yang disisipi 1%, 3%, 5%, 7%, dan 9% Ag yang disintesis dengan metode kopresipitasi. Eksperimen kinetika dilakukan melalui penentuan konsentrasi remazol yellow yang tersisa setelah interaksi ZnO dan ZnO-Ag dengan larutan remazol yellow yang disinari UV selama 0, 20, 40, 60, 80, 100, 120 dan 140 menit. Selanjutnya data dianalisis mengikuti model kinetika reaksi orde pertama. Hasil penelitian menunjukkan bahwa laju reaksi fotodegradasi oleh ZnO meningkat dengan penambahan konsentrasi dopan AgA research on photodegradation kinetics of remazol yellow using ZnO and Ag-doped ZnO (1, 3, 5, 7 and 9 wt% Ag) synthesized by co-precipitation method had been studied. Kinetics experiment was performed by determining the concentration of remazol yellow remained after interaction of ZnO and ZnO-Ag with remazol yellow solution that were irradiated by UV-light at 0, 20, 40, 60, 80, 100, 120 and 140 minutes. Data obtained was analyzed using firs-order kinetics model. The results showed that photodegradation rate was increased with the increasing Ag concentration.
