The effect of addition Ag and MnO2 nanoparticles in the hydrogen storage of ethyl 2-((5-methoxybenzo[d]thiazol-2-yl)thio)acetate (organic: Inorganic nanohybrids)

Abstract

Abstract This research included the synthesis of ethyl2-(benzo[d]thiazol-2-ylthio)acetate (EBTA) by reacting 2-mercaptobenzothiazole with ethylchloroacetate in the presence of potassium hydroxide. The compound was characterized using 1HNMR and FTIR. This compound was used to prepare two of its organic: inorganic nanohybrids with nano-manganese oxide (EBTA-MnO2) and with nano-silver (EBTA-Ag). The resulting composites were characterized using FTIR, XRD, SEM, EDX and TEM. The measurements proved that the reaction occurred successfully through the one-step reaction. These compounds were used in the application of hydrogen storage, and the study proved that the addition of these nanomaterials gave a great ability to increase hydrogen storage. The results showed that the compounds (EBTA), (EBTA-Ag) and (EBTA-MnO2) gave 0.99, 3.63 and 4.05 wt% hydrogen storage capacity, respectively. Also the study showed that the nano-hybrid (EBTA-MnO2) gave more storage efficiency than (EBTA-Ag), because manganese oxide contains two oxygen atoms, which act as effective real stores to increase the capacity hydrogen storage.
