Journal of Research and Development on Nanotechnology <p style="text-align: justify;">Journal of Research and Development on Nanotechnology (JRDN) a multidisciplinary peer-reviewed journal, which encompasses all aspects related to the state-of-the-art science and technology of nanosized and nanostructured materials, including their design, synthesis, characterization, functionalization, and application. The application includes, but is not limited to, catalysis, photocatalysis, energy conversion, electronics, medicine, sensor, and drug delivery. Both experimental and computational works are equally encouraged. In addition to original research articles, JRDN offers reviews and perspectives highlighting the recent progress and distinctive views on nanotechnology. The journal also welcomes the discussion of nanotechnology from the educational and societal points of view.</p> <p style="text-align: justify;"><strong>ISSN: 2808-4942</strong></p> en-US (Dr. Grandprix T.

CuBDC was characterized by Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and nitrogen physisorption. The crystallite size and productivity of CuBDC using [bmim][BF₄], [bmim][DCA], MTBS as electrolytes were 24.7 nm, 22.1 nm, 20.5 nm, and 236 mg/h, 69 mg/h, 291 mg/h, respectively. Bulkier structure of ammonium-based RTILs resulted CuBDC with a smaller crystallite size and higher productivity compared to imidazolium-based RTILs.</p> Laela Mukaromah, Yessi Permana, Aep Patah Copyright (c) 2022 Journal of Research and Development on Nanotechnology Mon, 04 Apr 2022 00:00:00 +0700 Green synthesis of Au coated on ZnO nanoparticles using orange peel extract and its application for electrochemical detection of formaldehyde <p>We report the facile preparation of Au coated ZnO nanoparticles via a two-step green synthesis route. The aqueous of orange peel extract (OPE) was used both as biocomplexing and bioreducing agents, while the Zn(NO<sub>3</sub>)<sub>2 </sub>and HAuCl<sub>4 </sub>were employed as precursors. Initially, OPE was prepared to synthesize the ZnONPs, followed by the reduction of HAuCl<sub>4</sub>, generating Au coated on ZnO nanoparticles (Au/ZnONPs). The IR spectra at around 438.95 cm<sup>-1 </sup>confirmed the presence of Zn-O absorption in the nanoparticles, while it was not observed in the OPE. Further characterization using XRD and SEM-EDX indicated that the spherical of Au was successfully coated on the sponge-like structure of ZnO with the crystalline size of ZnONPs and Au/ZnONPs were 21.30 and 26.67 nm, respectively.&nbsp; The modified Au/ZnONPs on graphite paste electrode showed the excellent electrochemical detection of formaldehyde solution by the linearity range from 1 to 100 mM (R<sup>2</sup>=0.9945) with LOD of 10.27 mM and RSD of 0.39%. In addition, the modified electrode showed high selectivity toward formaldehyde, instead of ethanol.</p> Wiyogo Prio Wicaksono, Nabilla Dinnia, Ika Yanti, Gani Purwiandono, Ganjar Fadillah Copyright (c) 2022 Journal of Research and Development on Nanotechnology Tue, 12 Apr 2022 00:00:00 +0700
