Mesoporous Ni<sub>0.85</sub>Se Nanospheres Grown in Situ on Graphene with High Performance in Dye-Sensitized Solar Cells
Mesoporous
Ni<sub>0.85</sub>Se nanospheres grown on graphene were synthesized
via the hydrothermal approach. Because of the exceptional electron-transfer
pathway of graphene and the excellent catalytic ability of the mesoporous
Ni<sub>0.85</sub>Se nanospheres, the nanocomposites exhibited excellent
electrocatalytic property as the counter electrode (CE) of dye-sensitized
solar cells. More catalytic active sites, better charge-transfer ability
and faster reaction velocity of Ni<sub>0.85</sub>Se@RGO (RGO = reduced
graphene oxide) CE led to faster and more complete I<sub>3</sub><sup>ā</sup> reduction than Pt, Ni<sub>0.85</sub>Se, and RGO CEs.
Furthermore, the power conversion efficiency of Ni<sub>0.85</sub>Se@RGO
CE reached 7.82%, which is higher than that of Pt CE (7.54%). Electrochemical
impedance spectra, cyclic voltammetry, and Tafel polarization were
obtained to demonstrate positive synergetic effect between Ni<sub>0.85</sub>Se and RGO, as well as the higher catalytic activity and
the better charge-transfer ability of Ni<sub>0.85</sub>Se@RGO compared
with Pt CE
<i>In Situ</i> Formed Ti/Nb Nanocatalysts within a Bimetal 3D MXene Nanostructure Realizing Long Cyclic Lifetime and Faster Kinetic Rates of MgH<sub>2</sub>
Magnesium hydride (MGH) is a high-capacity and low-cost
hydrogen
storage material; however, slow kinetic rates, high dehydrogenation
temperature, and short cycle life hindered its large-scale applications.
We proposed a strategy of designing novel delaminated 3D bimetal MXene
(d-TiNbCTx) nanostructure
to solve these problems. The on-set dehydrogenation temperature of
MGH@d-TiNbCTx composition
was reduced to 150 Ā°C, achieving 7.2 wt % of hydrogen releasing
capacity within the range of 150ā250 Ā°C. This composition
absorbed 7.2 wt % hydrogen within 5 min at 200 Ā°C and 5.5 wt
% at 30 Ā°C within 2 h, while the desorption capacity (6.0 wt
%) was measured at 275 Ā°C within 7 min. After 150 cycles at 250
Ā°C, the 6.5 wt % capacity was retained with negligible loss of
hydrogen content. These results were attributed to the catalytic effect
of in situ-formed TiH2/NbH2 nanocatalysts, which lead to dissociate the MgāH bonds and
promote of kinetic rates. This unique structure paves great opportunities
for designing of highly efficient MGHs/MXene nanocomposites to improve
the hydrogen storage performance of MGHs
