Nanostructured thermoelectric materials of GeSe1-xTex (0 ≤ x ≤ 0.2) alloys were prepared by a novel hydrogen decrepitation method and their structural, morphological, thermoelectric properties were investigated. The XRD analysis...
In
the present exploration, a few Si–B–N derivatives
are derived to adsorb Li ions and CO
2
gas molecules for
the potential application of metal–air batteries. The newly
derived structure’s bond lengths are as follows: Si=Si,
2.2 Å; Si–B, 1.9 Å; Si–N, 1.7 Å; and
B–N, 1.4 Å, consistent with the experimental results of
relevant structures. The stability of the newly derived structures
is examined by the atom-centered density propagation study by varying
the temperature from 270 to 400 K, and no structural variations are
observed throughout the dynamics. Li adsorption on the Si
4
B
2
ring has the maximum binding energy of −3.9
eV, and the result is consistent with the previous results. The rings
with the 2:1 silicon–boron ratio provide strong adsorption
for Li atoms. The calculated maximum electromotive force of the newly
derived sheets is 0.56 V with the maximum theoretical density of 783
Wh/kg. Similarly, the maximum adsorption of CO
2
on the
sheet is −0.106 eV, which is considerably higher than that
on graphene and its derivatives. CO
2
adsorption has been
carried out in the presence of water molecules to investigate the
change in CO
2
adsorption with the moisture (water) content,
and the results show no significant change in the adsorption of CO
2
with moisture. However, water has a strong interaction with
the maximum interaction energy of −0.72 eV. Further, to explore
the potential ability of the sheets, each sheet’s edges are
examined as hydrogen storage expedient and the surface as an artificial
photosynthesis platform. The Si
4
B
2
ring is more
favorable for the adsorption of H atom with the chemisorption of −7.138
eV. Similarly, all of the major UV-absorption spectral peaks fall
between 450 and 800 nm, which shows that the sheet can be used as
an artificial photosynthesis platform.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
