Abstract
Nowadays, carbon dots (CDs) with a variety of structures and compositions are widely applied in the petroleum industry, including tracers, modification of interfacial properties and regulation of rheological properties due to their excellent modifiability, environmental compatibility, straightforward synthesis, and outstanding photoluminescent properties. In this review, we summarize the applications of CDs in the petroleum industry and elucidate the effects of CDs based on the classification of application scenarios. In addition, we briefly analyze the relationship between the structure of CDs and their performance, identify the challenges we are currently facing, and discuss the structural characteristics of high-performance CDs along with their potential future applications. The discussion presented in this article is based on research on CDs and the petroleum industry. By combining these two areas, this review is expected to provide guidance to researchers working in related areas. Meanwhile, we also hope this review can offer innovative ideas for further applications of CDs in the petroleum industry.
