Introduction
Graphene materials have excellent electrical, thermal and mechanical properties and are used in electrothermal applications such as lithium-ion batteries, integrated circuits, 5G communications, and new displays:
The field shows broad industrial application prospects: The oxygen content and carbon-to-oxygen ratio (C/O) of graphene materials directly affect its electrothermal application performance:
Important characteristic parameters are also key indicators for identifying the type of graphene or graphene oxide (GO) materials, and can also be used to evaluate product quality and evaluation:
Estimate the degree of reduction of reduced graphene oxide (rGO): With the rapid increase in the application scale of graphene material industry and the continuous expansion of application scenarios,
With the development of graphene materials, there is an urgent need for accurate and reliable measurement of oxygen content and C/O of graphene materials, especially for graphene powder and graphene slurry:
These two main industrial application forms of materials: X-ray photoelectron spectroscopy (XPS) is a method with high identification ability for the chemical properties of material surface:
It is an advanced analysis technology with high power and high sensitivity, especially suitable for surface analysis of solid materials: It has the advantages of small sample consumption and no need for sample pre-processing and analysis:
It is fast, can obtain the chemical state information of the element being measured, and is very destructive to the sample: It is used for the testing and analysis of graphene materials:
At this time, not only the atomic fractions of carbon and oxygen in the graphene material can be obtained, but also the distribution of carbon-oxygen (CO) and carbon-carbon (CC) chemical bonds can be obtained
Determine the type of graphene material: This document is based on the Versailles Scheme for Advanced Materials and Standards (VAMAS) international comparison study, describing
This paper introduces a testing method for measuring the oxygen content and C/O of graphene powder using XPS, and provides the parameters of the two key characteristic parameters of oxygen content and C/O:
Examining technical indicators provides the necessary technical basis for graphene companies to carry out production, research and development and quality control of graphene materials and related products:
It enables supply and demand parties in the graphene industry chain to carry out mutually agreed product performance evaluation and specification confirmation:

single-layer graphene;monolayergraphene
A single carbon atom is combined with three surrounding carbon atoms to form a honeycomb structure of carbon atom monolayer:
Note 1: It is an important building block of many carbon nanoobjects:
Note 2: Since graphene has only one layer, it is often called single-layer graphene: Graphene is abbreviated as 1LG to distinguish it from double layer graphite, which is abbreviated as 2LG:
ene and few-layer graphene, abbreviated as FLG:
Note 3: Graphene has boundaries and has defects and grain boundaries where carbon-carbon bonds are broken:
