“…This demonstrates that growth is anisotropic. The second‐placed (002) plane which presents all the grains are preferentially arranged along the c‐axis is the characteristics feature of ZnO nanorods [36–38] . As supported by the FE‐SEM results, it has been observed that hexagonal ZnO nanorod structures are formed as well as nanoparticles formed by growth in different directions.…”

“…The second-placed (002) plane which presents all the grains are preferentially arranged along the c-axis is the characteristics feature of ZnO nanorods. [36][37][38] As supported by the FE-SEM results, it has been observed that hexagonal ZnO nanorod structures are formed as well as nanoparticles formed by growth in different directions. When examined the XRD result of the Ag-doped ZnO-NR sample presented in Figure 3 (c), a notable shift in the 2 theta values of ZnO was not observed.…”

[36,40] The crystallite size and lattice parameters were calculated by using diffraction angle related to (100) and (002) peaks that is the highest intensity for ZnO material. Moreover, the crystallite size was determined with help of diffraction angle correspond to (111) peak that is the highest intensity for Ag material.…”

The ZnO nanorod (NR) structures used as photocatalyst in the photocatalytic degradation of methylene blue (MB) dye were synthesized by the hydrothermal method and doped with Ag using the chemical precipitation method. The results of Field Emission‐Scanning Electron Microscopes (FE‐SEM) showed that after the heat treatment, ZnO nanoplate structures were broken, leaving only hexagonal ZnO‐NR structures and Ag nanoparticles with a diameter of approximately 92 nm occurred on the ZnO‐NR surface as a result of Ag doping. The results of X‐Ray Diffraction (XRD) revealed that pure hexagonal ZnO crystals and face‐centered cubic Ag structures were present. The data showed that the photodegradation efficiency for 20 mg/L methylene blue (MB) dye without H2O2 reached 98 % at 300th minute and 100 % after 60 minutes in the presence of H2O2. The results showed that the Ag‐Doped ZnO‐NR structures immobilized into Ca and Cu alginate beads provide the high photocatalytic removal efficiency in the presence of H2O2 in a short time.

“…Sintesis hidrotermal adalah sebuah proses pembentukan kristal bahan keramik melalui reaksi fase tunggal atau heterogen di dalam sebuah media cairan, dan pada suhu (T > 25°C) beserta tekanan (P > 100 kPa) [7]. Dalam kajian sebelumnya [8,9], kami telah berhasil mensintesis struktur batang mikro-nano ZnO menggunakan metode hidro-termal bersuhu rendah. Namun struktur batang ZnO yang dihasilkan masih dalam rentang diameter yang cukup besar dan dari hasil difraksi sinar-X yang didapatkan, diketahui bahwa kemurnian ZnO yang dihasilkan masih rendah.…”

Abstrak – Kajian terhadap difraksi sinar-X struktur nano ZnO dengan waktu sonikasi yang berbeda telah dilakukan menggunakan metode hidrotermal-sonokimia. Variasi waktu sonikasi yang digunakan dalam kajian ini adalah 0 (tanpa sonikasi), 30, 45, dan 60 menit. Pola difraksi sinar-X diplotkan dan dibandingkan untuk mengetahui struktur, kristalinitas dan kemurnian ZnO yang dihasilkan. Estimasi ukuran kristal ZnO juga dihitung menggunakan persamaan Scherrer. Hasil penelitian menunjukkan bahwa struktur nano ZnO yang disintesis tanpa proses sonikasi memiliki kemurnian kristal yang rendah dengan ukuran kristal yang sedang berkisar dari 22,36 – 32,90 nm. Proses sonikasi telah menyebabkan kristalinitas dan kemurnian ZnO meningkat jadi lebih baik. Namun, memperpanjang waktu sonikasi hingga 45 sampai 60 menit menyebabkan membesarnya ukuran kristal ZnO. Waktu sonikasi yang paling optimal adalah 30 menit dimana mampu menghasilkan ZnO dengan kristalinitas dan kemurnian yang baik dan rentang ukuran kristal ZnO yang lebih kecil antara 22,09 – 21,97 nm. Kata kunci: difraksi sinar-X, struktur nano, ZnO, sonikasi, Scherrer Abstract – Research on the X-ray diffraction study of ZnO nanotructure synthesized at different sonication times has been done using hydrothermal-sonochemical method. Sonication variation times that were used in this study were 0 (without sonication), 30, 45, and 60 minutes. The X-ray diffraction patterns were plotted and compared to understand the structure, crystallinity and purity of the resulted ZnO. The estimated crystallite size of ZnO nanostructure were also calculated using Scherrer equation. The results showed that the ZnO nanostructure synthesized without sonication process has a low crystal purity and a fair crystallite size in the range of 22.36 - 32.90 nm. Sonication process has led to a better crystallinity and purity of ZnO. However, longer sonication times up to 45 to 60 minutes has caused to the larger crystal size of ZnO. The most optimum sonication time was found to be 30 minutes which resulted in a good crstallinity and purity of ZnO and smaller crystallite size in the range of 22.09 – 31.97 nm.Key words: X-ray diffraction, nanostructures, ZnO, sonication, Scherrer
