Facile construction of ultrathin standing α-Ni(OH)2 nanosheets on halloysite nanotubes and its enhanced electrochemical capacitance - Journal of Materials Chemistry A (RSC Publishing)
One-dimensional nanostructure of ultrathin standing α-Ni(OH)2 nanosheets@halloysite nanotubes is synthesized through one-step facile precipitation method. The nanocomposites exhibit high capacitance (1677 F g-1) and excellent cycling stability (100 % capacity retention after 2000 cycles) due to their ultrathin and standing nanosheets and intense cation/anion exchange performance of halloysite nanotubes. The remarkable electrochemical performance will undoubtedly make the hybrid structures attractive for high-performance supercapacitors.
