Supercapacitors have been widely explored as electrical energy storage devices because of the long cycle life, high power density, and high charge-discharge rate. [1] Compared to the electrical double-layer capacitor, pseudocapacitors (PCs), featuring

Bi 2 S 3 and Sb 2 S 3 nanorods were synthesized from single-source precursors M(S 2 CNEt 2 ) 3 (M ) Bi, Sb) via a hydrothermal treatment. The X-ray powder diffraction patterns show that both of the products belong to the orthorhombic M 2 S 3 phase. Energy-dispersive X-ray analysis shows the products are phase pure. Transmission electron microscopic (TEM) and scanning electron microscopy (SEM) studies reveal the rodlike appearance of either Bi 2 S 3 or Sb 2 S 3 with a diameter in the range of 50-400 nm and a length in the range of 1-7 µm. The experimental results show that the nanorods can be prepared in protic solvent under experimental conditions (at 115-170 °C for 10 h). A possible mechanism is discussed.
