“…RF-RT-24 h and RF-LT-24 h have a band at 1470 cm À1 , which is attributed to the -C-H vibration on -CH 2and -O-CH 2connected between oligomers, indicating that the degree of crosslinking in the system further increases with hydrothermal reaction and aging, and the band at 1287 cm À1 becomes weaker, which proves that the ether connection between oligomers is reduced, and it also conrms that the degree of crosslinking in the system increases. [22][23][24] To further characterize the microstructure of SSAC and HSGC carbonized by RF-RT-24 h, we performed TEM characterization. Fig.…”

“…Urea is one of the major fertilizers, and CO 2 is the source for it [26]. The urea is prepared from ammonia and CO 2 in fertilizer [28] and also in fabrication process of various types of polymers, such as melamine and urea-formaldehyde resin [29][30][31][32]. Salicylic acid is produced from phenol and CO 2 via the Kolbe-Schmitt reaction [33].…”

The storage, utilization, and control of the greenhouse (CO2) gas is a topic of interest for researchers in academia and society. The present review article is dedicating to cover the overall role of ionic liquid-modified hybrid materials in cycloaddition reactions. Special emphasis is on the synthesis of various cyclic carbonate using ionic liquid-based modified catalysts. Catalytic activity studies have discussed with respect to process conditions and their effects on conversion and product selectivity for the reaction of cycloaddition of CO2 with styrene oxide. The reaction temperature and the partial pressure of CO2 have found to play a key role in cyclic carbonate formation. The role of other influential parameter (solvent effect) is also discussed for the conversion of cyclic/aromatic oxides to polycarbonate production. Our own research work that deals with ionic liquid-based halide-modified mesoporous catalyst (MCM-41 type) derived from rice husk waste has also been discussed. Finally, the role of carbon dioxide activation and ring-opening mechanisms involved in the cyclic carbonate product formation from CO2 have been discussed.

“…[ 34 ] For mMF/Ti 3 C 2 T x , the characteristic peaks at 1554 and 803 cm −1 belong to the skeleton vibrations of the triazine ring, while the peak at 1326 cm −1 is related to the stretching vibration of –CH 3 –; besides, the vibration absorption of C–O–C also appears at 1148 and 997 cm −1 . [ 35 ] These results prove that MF resin has been assembled onto the Ti 3 C 2 T x nanosheets. After carbonization, the characteristic peaks of MF in NPMC/Ti 3 C 2 T x basically disappear, while the characteristic peak of –C═N is found at 685 cm −1 , consistent with the related report.…”

“…After carbonization, the characteristic peaks of MF in NPMC/Ti 3 C 2 T x basically disappear, while the characteristic peak of -C═N is found at 685 cm −1 , consistent with the related report. [35] To further analyze the elemental compositions of NPMC/Ti 3 C 2 T x , an X-ray photoelectron spectrometry (XPS) technique was performed. The full survey XPS spectrum demonstrates the existence of Ti, C, O, N, and P elements (Figure 3e), in line with the above EDX results.…”

The rational construction of Ti3C2Tx MXene‐based composites has been deemed as a popular way to improve their electrochemical energy storage performances owing to the unique two‐dimensional (2D) structure, excellent conductivity, and good flexibility. However, it remains a major challenge to assemble mesoporous carbon onto Ti3C2Tx with fewer oxygen‐containing groups by using surfactants with short hydrophilic segments. In the work, we propose a molecular engineering assembly strategy for the growth of N,P co‐doped mesoporous carbon onto Ti3C2Tx nanosheets (NPMC/Ti3C2Tx) under the assistance of phytic acid by using melamine‐formaldehyde resin and pluronic P123 (PEO20PPO70PEO20) as the carbon/nitrogen source and soft template, respectively. The detailed investigations reveal that phytic acid with abundant hydroxyl groups can effectively enhance the hydrogen bond interactions among P123, carbon precursor, and Ti3C2Tx nanosheets, thus ensuring the efficient assembly of mesoporous carbon onto Ti3C2Tx. The obtained NPMC/Ti3C2Tx composite demonstrates a set of merits, including cylindrical mesopore, N,P co‐doping, and a good combination of mesoporous carbon and Ti3C2Tx nanosheets. As a result, it exhibits an improved lithium‐ion storage performance, delivering a high reversible capacity of 556.3 mA h g−1 after 100 cycles at 0.1 A g−1. The present work provides a feasible molecular engineering assembly route for the rational design of high‐performance Ti3C2Tx MXene‐based electrodes.
