One pot hydrothermal growth of hierarchical nanostructured Ni3S2 on Ni foam for supercapacitor application

Synthesis and remarkable capacitive performance of reduced graphene oxide/silver/nickel-cobalt sulfide ternary nanocomposites

“…With the increase of current density, the diffusion rate of OHanion becomes relatively slow, and thus only the outer active surface of the electrode material can be utilized during the redox process, resulting in a drop in specific capacitance [42]. [47,48].…”

Catalytic steam gasification of n-C5 asphaltenes by kaolin-based catalysts in a fixed-bed reactor

“…Recently, Ni 3 S 2 has been synthesized under hydrothermal conditions[25,26] starting from foam nickel and an aqueous soluble S-compound with temperatures around 150 -200 C. The experimental conditions employed in our work with NiO-based catalyst, i.e.…”

Hierarchical ultrathin NiAl layered double hydroxide nanosheet arrays on carbon nanotube paper as advanced hybrid electrode for high performance hybrid capacitors

“…With these encouraging features, SCs has been adopted widely in many fields where high power density and long cycling stability are highly desirable [5,6]. However, compared with rechargeable batteries, the energy density of commercial SCs is still too low (usually < 10 Wh kg -1 ) to come into practical applications [7].…”
