Ultrasonic-assisted fungi modification of lignocellulose-derived hierarchical porous carbon for efficient desalination

One/Two-Step Contribution to Prepare Hierarchical Porous Carbon Derived from Rice Husk for Supercapacitor Electrode Materials

“…The (002) reflections between 20 and 30° become gradually narrowing and strong with increasing carbonization temperature, indicating that a high temperature could enhance the electric conductivity of carbon materials . This is related to the increased graphitization degree of carbon materials, as previously reported …”

“…All RHPCs showed rectangle-shaped CV curves, exhibiting a typical electrochemical double-layer capacitance behavior. , The conductivity of RHPCs increased with increasing carbonization temperature, which was associated with the corresponding specific surface area. RHPC-1000 had the highest specific surface area (643.48 m 3 /g), resulting in high immigration of the electrolyte ions into the electrode during charging and discharging and leading to the highest specific capacitance (78.70 F/g) in the GCD test . It was found that RHPC-1000 showed relatively small charge transfer resistance and the lowest equivalent series resistance among porous carbon samples (Figure c).…”

Figure 9d shows the cycling stability of RHPC-1000 for 10 000 charge−discharge cycles under 200 mV/s extreme scanning, and the CV plots of the 1st and 10 000th cycles were compared in the middle chart.…”

Urea-Assisted Green Synthesis of CeO2 Nanoparticles/Porous Carbon Composites for Microwave Absorption

“…Additionally, using high-porosity structural materials for body components is preferred . Biomass-derived porous carbon has lately received substantial attention in various research fields, including adsorbent materials, capacitors, and lithium-ion batteries, due to its low cost, environmental friendliness, intrinsic heteroatom doping, and unusual structure. Importantly, these qualities make biomass porous carbon composites suitable for MA applications.…”
