This study aims to environmentally synthesize and fully characterize CdO nanoparticles by utilizing an eco‐friendly process that involves Crocus sativus in its reaction with cadmium ions. The CdO nanoparticles underwent characterization, and their purity was confirmed through XRD and UV‐Vis spectroscopy. Additionally, scanning electron microscope and transmission electron microscopy revealed that the prepared cadmium oxide nanoparticles exhibited polymorphism, with diameters ranging between 42 and 67 nm. Furthermore, the Fourier transformation infrared spectroscopy showed the main bands of cadmium oxide at 1047, 542, and 1310 cm−1. Furthermore, the cadmium oxide nanoparticles were employed in a study focusing on gas storage, particularly hydrogen (H2) storage. The results of the hydrogen storage study demonstrate that the maximum H2 uptake reached 2.85 Wt.%H2 at a pressure of 69 bar at 77 K, with ∆H = 0.62607 KJ/mol H2 and ∆S = 3.35697 J/mol H2·K. Moreover, thermodynamic investigations at four different temperatures confirm that the maximum H2 uptake can be achieved within a pressure range of 69–86.2 bar.

“…It is also clear from these images that the shapes of these nanoparticles were between spherical to oval shapes, as it is noted that there are some irregular particles in addition to the presence of some grouping of a number of particles in same area. This variety of nano‐structures is very important as a solid surface for hydrogen gas uptake, because it will generate internal and external caves and pores, which are very useful in storing hydrogen gas inside these structures 14,74 …”

Enhanced hydrogen storage capacity of graphene oxide through doping with copper ferrite nanoparticles

The aim of this study was to prepare and characterize nanocomposites consisting of graphene oxide (GO) and copper ferrite (CuFe2O4) in different doping ratios (1%‐5%) and investigate their potential for storing hydrogen gas. The prepared nanocomposites were characterized using FTIR, XRD, SEM, and TEM. The results showed that hydrogen storage at 20°C was not possible with GO alone, but the incorporation of different proportions of copper ferrite nanoparticles significantly improved the hydrogen storage properties of the composite materials. The optimal percentage of copper ferrite was found to be around 3%, and it was observed that the percentage of ferrite added is crucial in determining the hydrogen storage properties of the nanocomposites. The best hydrogen storage value of 3.3% was achieved at a temperature of 20°C and a pressure of 80 bar within just 60 seconds. The adsorption of the composite material was found to be of the second type, with a re‐creation coefficient greater than 0.97 for all the materials tested, indicating favorable adsorption. The b value was up to 0, further confirming the favorable adsorption. Overall, the results demonstrate that the incorporation of copper ferrite nanoparticles can significantly improve the hydrogen storage properties of graphene oxide, and careful selection of the doping ratio is necessary to achieve the optimal performance. These findings have potential implications for the development of efficient hydrogen storage materials for clean energy applications.

A silver complex was prepared with benzisothiazolinone ligand, which was used to prepare new phosphorus‐rich complexes with dppe and dppp. All complexes were diagnosed by FTIR, 1H‐NMR, 31P‐NMR, CHN, and molar conductivity. The results proved that phosphines were labile, therefore 31P‐NMR was measured by cryoprotection at different temperatures. As a promoted effort to obtain direct experimental proof for the dimeric and the labile nature of [Ag(bit)(diphos)]2 complexes in solution, the 31P{1H}‐NMR spectrum of mixed (dppe/dppp) ligand complexes was measured. It was anticipated that an exchange of phosphines occurred between [Ag(bit)(dppe)]2 and [Ag(bit)(dppp)]2 complexes. However, a distribution of the dppp and dppe should result, and complex with compositions of [Ag2(bit)2(dppe)(dppp)] will be formed. The phosphine‐containing complexes were used in hydrogen storage study. The results proved that hydrogen storage values were initially similar for [Ag(bit)(dppp)]2 and [Ag(bit)(dppe)]2, but increased significantly for [Ag(bit)(dppe)]2 at higher pressures to reach 4.35 wt% at 90 bar.
