The use of free‐standing carbon‐based hybrids plays a crucial role to help fulfil ever‐increasing energy storage demands, but is greatly hindered by the limited number of active sites for fast charge adsorption/desorption processes. Herein, an efficient strategy is demonstrated for making defect‐rich bismuth sulfides in combination with surface nitrogen‐doped carbon nanofibers (dr‐Bi2S3/S‐NCNF) as...
In article number 1602866, Yue‐E Miao, Tianxi Liu, and co‐workers use bacterial cellulose‐derived carbon nanofibers to successfully assist with the uniform growth of few‐layered MoSe2 nanosheets. This is beneficial to synergistically achieve structural and electronic modulations for MoSe2‐based hydrogen evolution reaction catalysts.
Molybdenum diselenide (MoSe2) has emerged as a promising electrocatalyst for hydrogen evolution reaction (HER). However, its properties are still confined due to the limited active sites and poor conductivity. Thus, it remains a great challenge to synergistically achieve structural and electronic modulations for MoSe2‐based HER catalysts because of the contradictory relationship between these two...
The development of biomass‐based energy storage devices is an emerging trend to reduce the ever‐increasing consumption of non‐renewable resources. Here, nitrogen‐doped carbonized bacterial cellulose (CBC‐N) nanofibers are obtained by one‐step carbonization of polyaniline coated bacterial cellulose (BC) nanofibers, which not only display excellent capacitive performance as the supercapacitor electrode,...
On page 3235, Y.‐E. Miao, T. X. Liu and co‐workers successfully anchor ultrathin nickel‐cobalt layered double hydroxide (Ni‐Co LDH) nanosheets onto the surface of nitrogen‐doped carbonized bacterial cellulose (CBC‐N) nanofibers to form CBC‐N@LDH composite electrodes. The thus assembled asymmetric supercapacitor exhibits a high specific energy of 36.3 Wh kg−1 at a power density of 800.2 W kg−1 for...
