Indirect growth of mesoporous Bi@C core-shell nanowires for enhanced lithium-ion storage.

Nanoscale

Dai R, Wang Y, Da P, Wu H, Xu M, Zheng G.
PMID: 25260037
Nanoscale. 2014 Nov 07;6(21):13236-41. doi: 10.1039/c4nr04378b.

In this paper, we propose a facile synthetic strategy for uniform bismuth@carbon (Bi@C) core-shell nanowires, which are prepared via controlled pyrolysis of Bi2S3@glucose-derived carbon-rich polysaccharide (GCP) nanowires under an inert atmosphere. Carbonization of GCP and pyrolysis of Bi2S3 into...
