“…This result is consistent with the (1 0 0) face of graphene, which proves that ZCQDs are mainly graphene structures. − According to Raman spectroscopy (Figure c), peak D caused by disorderly vibration of graphene, which can reflect graphene defects, and peak G caused by in-plane vibration of the sp 2 carbon atom, which can reflect the thickness of the graphene material, are at 1337.39 and 1594.95 cm –1 , respectively, in ZCQDs. , The ratio of peak D to peak G intensity can be used to obtain the degree of disorder of graphitic carbon, and the ID/IG value can be obtained by calculation as 0.86. Therefore, it can be seen that the degree of graphitization of ZCQDs is good, which is mainly stacked by sp 2 hybrid carbon . In conclusion, ZCQDs are carbonized by cross-linking polymerization of various components in Z.…”

Eco-friendly self-doped carbon quantum dots (ZCQDs) with excellent corrosion inhibition ability were prepared via solid-phase pyrolysis only using Zanthoxylum bungeanum leaves as the raw material. Compared with the relevant research, a simpler and higher yield (25%) preparation process for carbon quantum dots was proposed. ZCQDs were characterized by transmission electron microscopy and X-ray photoelectron spectroscopy, and the average size of ZCQDs with multitudes of O- and N-containing functional groups was about 2.53 nm. The prepared ZCQDs were used to inhibit the corrosion of Q235 steel in HCl solution, and the inhibition behavior was investigated through weight loss, electrochemical test, surface analysis, and adsorption thermodynamic analyses. The results showed that the ZCQDs, acted as a mixed corrosion inhibitor, have an effective corrosion inhibition for Q235, the corrosion inhibition efficiency reached 95.98% at 200 mg/L, and at this concentration, effective protection of at least 132h (IE > 90%) is provided. Moreover, the adsorption mechanism of ZCQDs was consistent with that of Redlich–Peterson adsorption, including chemisorption and physisorption. A new corrosion inhibition mechanism of ZCQDs has been thoroughly studied and proposed; ZCQDs have functional groups containing O and N, which can form a protective barrier through physical adsorption and chemisorption, but the coverage of the protective film is low at low concentrations. With the increase of concentration, the protective film formed by ZCQDs on the metal surface will first increase the coverage and then adsorb more ZCQDs on the protective film to form a thicker and denser protective film to protect the metal. The carbon quantum dots prepared in this paper have advantages including a green, renewable precursor, a fast method, high yield, and excellent corrosion inhibition. Therefore, this work can inspire and facilitate, to a certain extent, the future application of doped carbon quantum dots as efficient corrosion inhibitors in HCl solutions.

“…For nanoparticles in polar media, several limitations for adsorption processes must be considered, such as the increase in particle size, the difference in excess charges, and even precipitation. In a study on functionalized carbon nanotubes (FCNTs) as corrosion inhibitors of carbon steel, Hongyu Cen et al cited a three-parameter isotherm model with both Langmuir and Freundlich properties, i.e., the Redlich–Peterson (R–P) equation, which is suitable for heterogeneous and multilayer adsorption systems, as well as for the investigated nanoparticle adsorption behavior [ 85 , 86 ]. The Redlich–Peterson (R–P) equation can be represented by Equation (36).…”

Most studies on the corrosion inhibition performance of organic molecules and (nano)materials were conducted within “carbon steel/1.0 M HCl” solution system using similar experimental and theoretical methods. As such, the numerous research findings in this system are sufficient to conduct comparative studies to select the best-suited inhibitor type that generally refers to a type of inhibitor with low concentration/high inhibition efficiency, nontoxic properties, and a simple and cost-economic synthesis process. Before data collection, to help readers have a clear understanding of some crucial elements for the evaluation of corrosion inhibition performance, we introduced the mainstay of corrosion inhibitors studies involved, including the corrosion and inhibition mechanism of carbon steel/HCl solution systems, evaluation methods of corrosion inhibition efficiency, adsorption isotherm models, adsorption thermodynamic parameters QC calculations, MD/MC simulations, and the main characterization techniques used. In the classification and statistical analysis section, organic compounds or (nano)materials as corrosion inhibitors were classified into six types according to their molecular structural characteristics, molecular size, and compound source, including drug molecules, ionic liquids, surfactants, plant extracts, polymers, and polymeric nanoparticles. We outlined the important conclusions obtained from recent literature and listed the evaluation methods, characterization techniques, and contrastable experimental data of these types of inhibitors when used for carbon steel corrosion in 1.0 M HCl solution. Finally, statistical analysis was only performed based on these data from carbon steel/1.0 M HCl solution system, from which some conclusions can contribute to reducing the workload of the acquisition of useful information and provide some reference directions for the development of new corrosion inhibitors.

“…Hence, the search and development of novel inhibitors with high inhibitory capacity is always in great demand. [10][11][12][13][14][15][16][17] In general, conventional corrosion inhibitors are organic compounds containing hetero atoms (O, N, S, or P) and aromatic rings or long alkyl chains, for example, imidazole, pyrimidine, triazole, guanidine, acridine, Schiff-bases, etc. 9,[18][19][20][21][22] Particularly, inhibitor molecule with a relatively larger hydrophobic and conjugated skeleton could resist corrosion more effectively, in terms of surface coverage and electron donor-acceptor interaction with metal atoms.…”
