Carbon materials are considered to be one of the most promising materials for industrial applications because of their wide source, low cost, ease of preparation and non-toxicity. The structural characteristics of the carbon material will inherit the structural characteristics of the raw materials to a certain extent, so that the selection of the raw materials is more critical to the material structure, and becomes one of the research hotspots in the material field in recent years. Various biomass carbon materials have been reported, for example, carbon materials prepared using tea leaves, coconut shells, human hair, bamboo, cotton stalks, soybeans, waxberries, etc. as raw materials. In addition, it is desirable to enrich the element and functional group types of the carbon material by doping with hetero atoms so as to impart special application functions to the material. Such as nitrogen doping, the feedstock is co-heated with urea (nitrogen source) to produce a nitrogen-doped carbon material. It is also possible to purposefully select biomass materials with heteroatoms (e.g., N, P, S, B, etc.) by material selection.
Gram bacteria, especially gram-positive bacteria, have a thick (20-80nm) and dense peptidoglycan layer (15-50 layers), each 1nm thick, accounting for about 50-80% of the dry cell weight. Peptidoglycan is also called as sticky peptide, peptidoglycan scaffolds of various bacterial cell walls are the same, the composition and connection mode of tetrapeptide side chains are different according to strains, so that gram bacteria have a compact and ordered arrangement mode in structure, elements such as nitrogen, oxygen, sulfur, phosphorus and the like in different combination modes can be introduced due to the diversity of the tetrapeptide side chains in the composition, and the gram bacteria are used as carbon source materials and can possibly endow corresponding materials with special structure and functional characteristics.
