H2 storage abilities of some novel Pd(II) complexes containing 2H[1,4]benzothiazin-3(4H)-one

Novel dithiocarbamate–Hg(II) complexes containing mixed ligands: Synthesis, spectroscopic characterization, and H2 storage capacity

“…These results indicate the efficiency of complex (2) compared to the other complex, which is consistent with the results of the PXRD and BET measurements, where the size of the particles of this complex was lower which provided larger BET surface area. These results are good compared to previously published works [25,26,31] and the H 2 values, which are correlated with measurements of surface area, show that the hydrogen is stored as H 2 molecules within the pores of the material (physical storage). [25] While the results of BET of complexes ( 2) and (3) were 76.3 and 41.1 m 2 /g respectively, the BET results of some other complexes (complex (1) and complex 6) were too low; therefore, we did not examine their H 2 storage.…”

“…The results show that the BET surface area of complex (2) was 76.3 m 2 /g, while it was 41.1 m 2 /g for complex 3, and these results are in agreement with the results of particle sizes and with BET of our previous works. [25,26] This may be due to the increase in the surface area with decreasing size or due to the presence of SO 2 group in complex 2, causing high repulsion.…”

“…Among all hydrogen storage methods, the method of storage in the solid phase has been extensively used. [25][26][27][28][29] The most common chemicals used for this purpose are metal-organic compounds. [30,31] Our previous interests in the study of the coordination chemistry of heterocyclic ligands containing nitrogen, oxygen, and sulfur in their composition [26,[32][33][34] inspired us to choose the following ligands to receive more information about how N, O, and S compete between them in the coordination system around the metal studied.…”

“…As an alternative and green energy source, hydrogen gas is widely used, due to its high efficiency and high energy density and most importantly because its use does not generate any harmful combustion products.

“…Owing to the decrease in the amount of fossil fuels with the increase of pollutants in the environment in which we live, it is necessary to find eco‐friendly alternative ways to save energy. As an alternative and green energy source, hydrogen gas is widely used, due to its high efficiency and high energy density and most importantly because its use does not generate any harmful combustion products.
