“…Phosphorus, which has a larger covalent radius and lower electronegativity than N and S, can be favorable to donating electrons to form chemical bonds in carbon and enhance ion transport. For example, Sun et al [90] prepared P-doped carbon nanosheets (C-1) with a thickness of ca. 8 nm using sodium hypophosphite as an assistant and phosphorus source and coal tar pitch as a carbon source, as shown in Figure 9a.…”

Pitch-based carbon materials (PBCMs) are regarded as one of the most promising anodes used for alkali metal-ion (Li/Na/K) batteries due to the advantages of their low cost, high carbon yield, abundant resource, and environmental friendliness. However, PBCMs tend to be soft carbon with small layer spacing at high temperatures, resulting in undesirable reversible capacity and poor cycling stability during repeated charging and discharging, which limit their future development and application in energy storage systems. Up to now, many efforts are focused on the modification of the PBCMs to achieve excellent alkali metal-ion storage performance. In this review, the operation mechanisms and corresponding microstructural characteristics of PBCMs used for alkali metal-ion batteries are discussed. Moreover, the design and optimization strategies of PBCMs are summarized and discussed in detail, including structural adjustment strategy, heteroatom doping strategy, compound modification strategy, pre-oxidation strategy, and coating strategy, respectively. Furthermore, the research status and development prospects of PBCMs are presented, as well as a perspective on future research directions.

“…[17,25,125,126] Moreover, they can not only widen the interlayer spacing but also provide more defects and active sites, which is helpful to the combination of carbon layer and ions. [52,[127][128][129] Sun et al [130] obtained 8 nm P-doped ultrathin carbon nanosheets by pyrolysis of coal tar pitch assisted by sodium hypophosphite. Na + is stored in carbon nanosheets because of a pseudocapacitive mechanism, resulting in excellent rate capacity and long-term cycling stability.…”

It is significant for saving energy to manufacture superb-property batteries. Carbon is one of the most competitive anode materials in batteries, but it is hard for commercial graphite anodes to meet the increasingly higher energy-storage requirements. Moreover, the price of other better-performing carbon materials (such as graphene) is much higher than graphite, which is not conducive to massive production. Pitch, the cheap by-product in the petroleum and coal industries, has high carbon content and yield, making it possible for commercialization. Developing pitch-based anodes can not only lower raw material costs but also realize the pitch's high value-added utilization. We comprehensively reviewed the latest synthesis strategies of pitch-derived materials and then introduced their application and research progress in lithium, sodium, and potassium ion batteries (LIBs, SIBs, and PIBs). Finally, we summarize and suggest the pitch's development trend for anodes and in other fields.

“…Figure 2g displayed the C1s XPS spectra of FHM nanoparticles, which was potentially deconvoluted into three peaks. The peak at 284.8 eV was assigned to the C-C group, [34] while the peak centered at 286.3 eV could be assigned to C-O-C group. [35] The peak at 288.5 eV was ascribed to O-C═O, [36] which originated from the carboxylic group in histidine and MTX.…”

The continual growth of tumor cells requires considerable nutrient consumption. Methotrexate (MTX) is used to treat certain types of cancer by blocking the DNA and RNA productions through interfering one-carbon metabolism and de novo purine and pyrimidine synthesis. However, treatment of MTX may cause many serious adverse effects, which hamper its clinical application. Herein, the authors synthesize ferrous ions, histidine, and MTX assembled nanoparticles (FHM) to deliver MTX at tumor site and enhance the sensitivity of tumor cells to MTX with histidine catabolism. Furthermore, fasting-mimicking diet (FMD) is applied to intervene in the one-carbon metabolism and enhance the cytotoxicity of MTX. Meanwhile, FMD treatment can significantly augment the cellular uptake and tumor accumulation of FHM nanoparticles. Due to the triple inhibitions of the one-carbon metabolism, the proliferation of tumor cells is strongly disturbed, as which is highly replying on DNA and RNA production. Taken together, a 95% lower dose of MTX adopted in combined therapy significantly inhibits the growth of two types of murine tumors without evident systemic toxicity. This strategy may provide a promising nucleotide metabolism-based nanomedicine for cancer therapy.
