Conversing CO 2 into value-added chemicals endows electrochemical CO 2 reduction reaction (CO 2 RR) with the potential to tackle over issues induced by the increased CO 2 level in the atmosphere. The associated technological viability of this process is highly dependent on exploring efficient electrocatalysts. In this work, we successfully synthesized nitrogen and sulfur co-doped carbon nanosheets (NS-CNSs), which are comprehensively characterized by a variety of characterization techniques. When used as the catalyst for CO 2 RR, the NS-CNSs exhibit remarkably high catalytic activity and selectivity with a Faradaic efficiency of~85.4 % for CO production and long-term durability. The superior performance of this material majorly originates from the unique nanosheets structure with large porosity and the co-doped S and N in the nanosheets, which exposed larger electrochemical activity surface areas and more active sites for promoting CO 2 reduction.
Renewable biomass-derived carbon materials have attracted increasing research attention as promising electrode materials for electrochemical energy storage devices, such as sodium-ion batteries (SIBs), due to their outstanding electrical conductivity, hierarchical porous structure, intrinsic heteroatom doping, and environmental friendliness. Here, we investigate the potential of hierarchical N-doped porous carbon (NPC) derived from jackfruit rags through a facile pyrolysis as an anode material for SIBs. The cycling performance of NPC at 1 A/g for 2000 cycles featured a stable reversible capacity of 122.3 mA•h/g with an outstanding capacity retention of 99.1%. These excellent electrochemical properties can be attributed to the unique structure of NPC; it features hierarchical porosity with abundant carbon edge defects and large specific surface areas. These results illuminate the potential application of jackfruit rags-derived porous carbon in SIBs.
