A novel synthesis of carbon foam@Fe2O3 via hydrolysis-driven emulsion polymerization for supercapacitor electrodes

Constructing Fe2O3 nanoparticles in nitrogen-doped carbon materials to enhance the electrochemical sensing performance of Pb2+ and Cd2+

“…When the relative pressure was from 0.4 to 1.0, we saw that it showed an obvious hysteresis loop with an upward trend, indicating that this material also had abundant mesopores and macropores. 49–51 The result further proved that the Fe 2 O 3 @NCNPs-1.5 nanomaterial had a porous structure. As shown in Table S5,† the specific surface area of Fe 2 O 3 @NCNPs-1.5 was 292.25 m 2 g −1 as determined by the BET method, and S micro was 30.08 m 2 g −1 .…”

Extrinsic pseudocapacitive ultrathin 2D MoS2 nanoflakes clamped on 1D Sb2S3 nanorods: an advanced heterostructured anode for high-energy ammonium ion hybrid capacitors

“…Traditionally, carbon-based materials have been used as anodes due to their excellent electrochemical cycling stability. [25][26][27][28] However, the double-layer charge storage limits the capacitance of carbon anodes and causes a large kinetic imbalance between anode and cathode materials. This can negatively affect the capacitance and energy density of cells, as indicated by the equation 1 29 where C T , C 1 , and C 2 are the capacitances of the whole cell, cathode and anode electrodes, respectively.…”
