Graphene sheets functionalized by redox-active small aromatics can exhibit enhanced capacitance because of the introduced faradaic process. However, the immense number of possible mols. for energy storage makes the selection of the appropriate ones difficult. This study combines experiment and theory to unveil factors behind the different pseudocapacitance contributions of some aromatic isomers adsorbed onto graphene, aiming to provide a guideline for computationally screening out optimal mols. for supercapacitor electrodes. Eight kinds of mols. containing amino groups are intentionally selected to functionalize N-doped graphene (NG) and their electrochem. properties are compared. The HOMO level of a mol. is found to play an important role in rendering a high pseudocapacitance. Also, remarkable efficacies from two kinds of mols., 4-aminophenol and 1,5-naphthalenediamine (1,5-NAPD), are unveiled, and the role of the amino group in charge storage is discussed. As a result, the graphene film absorbed with 1,5-NAPD mols. shows a high specific gravimetric capacitance of 877 F/g within the voltage window of 1 V, corresponding to a high areal specific capacitance of 1.14 F/cm2 from the thin film with a mass loading of 1.3 mg/cm2. Also, the 1,5-NAPD/NG film shows good cycling stability, achieving 105% capacitance retention after 5000 charge-discharge cycles.3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.
3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. Reference of 3-(4-Aminophenoxy)aniline The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.
