Preparation of hierarchical porous carbon by pyrolyzing sargassum under microwave: The internal connection between structure−oriented regulation and performance optimization of supercapacitors

One-pot synthesis of biomass-derived porous carbons for multipurpose energy applications

“…[40][41][42] Compared with conventional heating, microwave heating shows some advantages, especially for reducing both the processing time and the use of activating agents (e.g., KOH). 41 According to reported studies, [43][44][45][46][47][48][49][50][51] the advantages and disadvantages of conventional and microwave heating methods for porous carbon production from biomass are highlighted in Table 2. For the one-pot microwave-assisted activation process, biomass is directly heated under microwave irradiation.…”

Recent Advances in Porous Carbon Materials as Electrodes for Supercapacitors

“…These impressive results and the related studies highlight the important role of the open porous structure in maintaining the capacitive performance of supercapacitors at ultra-low temperatures [145]. There are also researchers such as Sun et al, who investigated the relationship between the struc-tural characteristics of biomass porous carbon and the electrochemical performance of supercapacitors in order to find a valid correlation between the preparation process of symmetric supercapacitors and their application performance [146]. Based on the responsive experimental design, the pore structure of Sargassum bio-porous carbon (SPC) was adjusted by the synergistic optimisation of key parameters and the hierarchical Sargassum porous carbon with different pore characteristics was successfully prepared by microwaveparameter pyrolysis.…”

Pyrolysis of sargassum in a single mode microwave cavity: use of SiC and biochar as microwave absorbers

“…5 Only a few examples of macroalgae pyrolysis under microwave can be found in the literature but they show that macroalgae can produce a large amount of syngas by pyrolysis under microwave. 20,[28][29][30] Yu Hong et al 29 pyrolyzed porphyry (genus of red algae) at the laboratory scale in a multimode microwave cavity using silicon carbide (SiC) as the MA. 28 This study concluded that the porphyra macroalgae under microwave conditions is capable of producing a large amount of syngas (85.6-87.1 wt%) comparable to its valorization by conventional pyrolysis, and attributed this high gas production to the high carbohydrate content of the macroalgae (47.7 wt%).…”
