The influence of imidazolium- and ammonium-based room-temperature ionic liquids (RTILs) i.e., [bmim][BF₄], [bmim][DCA], and MTBS, respectively, as electrolytes on the crystallite size and productivity of CuBDC (BDC=1,4-benzenedicarboxylate) type metal-organic frameworks (MOFs) by electrosynthesis method via anodic dissolution was investigated. 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…

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(NO3)2 and HAuCl4 were employed as precursors. Initially, OPE was prepared to synthesize the ZnONPs, followed by the reduction of HAuCl4, generating Au coated on ZnO nanoparticles (Au/ZnONPs). The IR spectra at around 438.95 cm-1 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…

Performance evaluation of metal Neodymium Imprinted Polymers (Nd-IPs) through the polymerization of methyl metaacrylate with divinyl benzene in the presence of a metal complex Nd(III)-Xylenol Orange (XO) has been investigated. The adsorption capability towards Nd(III) ion were optimized based on ion retention parameters, such as pH, contact time, concentration, adsorption isotherm, and kinetic studies. The synthesized Nd-IPs obtained Nd(III) adsorption capacity reached 30.36 mg.g-1 at a pH of 5 with 20 minutes contact time. The isotherm studies showed the preference of Freundlich isotherm…
