Abstract
Graphite oxide (GO) with N doping is synthesized from the waste carbon source. The GO products obtained at 1200–1400 °C are utilized as nano-additive in synthetic engine oil. The GO is produced in the form of layered structure with Ca compound incorporation and functional groups. GO addition has improved the friction (2.8–21.1% reduction) and wear (8.2–18.5% reduction in worn volume) properties due to its easy shear force of layered structure. The maximum performance is achieved in the GO synthesized at 1300 °C. Study reveals the potential use of a waste carbon source converted to GO that can be directly used as nano-additive. © 2019 Elsevier Ltd
