Hierarchical Porous Carbons Derived from Renewable Poplar Anthers for High‐Performance SupercapacitorsChemElectroChem - Tập 5 Số 11 - Trang 1451-1458 - 2018
Jian Song, Wenzhong Shen, Jianguo Wang, Weibin Fan
AbstractHierarchical porous carbons with granular shape were prepared from waste biomass poplar anthers (PA) by pre‐carbonization and following KOH activation. The pore structure and surface chemistry of PA‐derived carbon can be controlled by adjusting the activation temperature. The material activated at 800 °C possesses a high surface area of 3639 m2... hiện toàn bộ

AbstractAn issue associated with lithium−sulfur (Li−S) batteries is polysulfide dissolution, leading to the serious crossover of polysulfide to the Li anode. To address this issue, we report on a multifunctional separator prepared by introducing a porous carbon/multi‐walled carbon nanotube (PC/MWCNT) composite into a commercial separator. It shows that the PC/MWCNT...... hiện toàn bộ
Cyclic Voltammetry is Invasive on Microbial ElectrosynthesisChemElectroChem - Tập 8 Số 17 - Trang 3384-3396 - 2021

AbstractCyclic voltammetry (CV) is expected to cause changes in the biocathode composition, especially when using low scan rates. A recent finding stated that CV triggered further biocatalytic activity in microbial electrosynthesis systems (MES), leading to the aim of our study: to investigate the invasiveness of CV on MES. The present study confirms that a CO... hiện toàn bộ

AbstractBlack phosphorus (BP) shows broad application in optical, photoelectric and semiconductor fields. Herein, BP nanosheets and few‐layer phosphorene were prepared by means of a solvent exfoliation method. The absorption and fluorescence spectra of BP were measured and dye‐sensitized solar cells (DSSCs) were fabricated using BP/TiO2 films a...... hiện toàn bộ
