Meso/Microporous Carbons from Conjugated Hyper-Crosslinked Polymers Based on Tetraphenylethene for High-Performance CO2 Capture and Supercapacitor

Abstract

In this study, we successfully synthesized two types of meso/microporous carbon materials through the carbonization and potassium hydroxide (KOH) activation for two different kinds of hyper-crosslinked polymers of TPE-CPOP1 and TPE-CPOP2, which were synthesized by using Friedel–Crafts reaction of tetraphenylethene (TPE) monomer with or without cyanuric chloride in the presence of AlCl3 as a catalyst. The resultant porous carbon materials exhibited the high specific area (up to 1100 m2 g−1), total pore volume, good thermal stability, and amorphous character based on thermogravimetric (TGA), N2 adsoprtion/desorption, and powder X-ray diffraction (PXRD) analyses. The as-prepared TPE-CPOP1 after thermal treatment at 800 °C (TPE-CPOP1-800) displayed excellent CO2 uptake performance (1.74 mmol g−1 at 298 K and 3.19 mmol g−1 at 273 K). Furthermore, this material possesses a high specific capacitance of 453 F g−1 at 5 mV s−1 comparable to others porous carbon materials with excellent columbic efficiencies for 10,000 cycle at 20 A g−1.

“…Recently, the rapid growing development and demand of miniaturized portable and wearable electronics has expressively amplified the importance for lightweight, stretchable, microscale and efficient power storage systems [ 1 , 2 , 3 ]. Modern life is also becoming more expedient day by day by the extensively utilization of fast remote-control smart devices, gadgets and recent development of internet-of-things (IoT) systems [ 4 , 5 ].…”

Advances in porous organic polymers: syntheses, structures, and diverse applications

“…synthesized two HCPs (TPE-CPOP1, TPE-CPOP2) based on tetraphenylethene as the main building unit and these obtained materials had high BET surface areas, amorphous structures, and high specific capacitances. 116 Furthermore, we prepared An-CPOP1 and An-CPOP2 through simple Friedel-Crafts alkylations of An-4Ph with 2,4,6-trichloro-1,3,5-triazine and formaldehyde dimethyl acetal as crosslinker reagents. 117 An-CPOP1 possessed a tubular nanotube structure, based on SEM imaging, while An-CPOP2 displayed a capacitance of 98.10 F g -1 at 0.5 A g -1 .…”

Microporous Carbon and Carbon/Metal Composite Materials Derived from Bio-Benzoxazine-Linked Precursor for CO2 Capture and Energy Storage Applications

“…Thus, extensive research efforts will be needed to develop novel materials possessing high specific surface areas that can increase the energy density of supercapacitors while maintaining their power density and cycling stability. In this regard, many porous organic polymers (POPs) featuring suitable pore size distributions—including covalent triazine frameworks (CTFs) [ 39 ], covalent organic frameworks (COFs) [ 40 , 41 , 42 ], hypercrosslinked porous polymers (HCPs) [ 43 , 44 ], conjugated microporous polymers (CMPs) [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ], metal–organic framework [ 48 , 49 , 50 ], and ferrocene-based conjugated microporous polymers [ 51 ]—have been developed to improve the performance of supercapacitors. Supercapacitors can store energy through faradaic (pseudocapacitance) and non-faradaic [electric double-layer capacitance (EDLC)] processes [ 43 , 44 , 45 , 46 , 47 ].…”

The energy densities of carbon materials suitable for use in supercapacitors can be enhanced through doping with heteroatoms and/or redox moieties, thereby providing the chance to merge the features of both pseudocapacitor and EDLC mechanisms [ 43 , 44 , 45 , 46 , 47 ].…”
