Abstract
In this study, a new system for fullerene preparation was designed based on the incomplete combustion of liquid
asphalt. Transmission electron microscopy, field emission scanning electron microscopy and energy-dispersive X-
ray (EDX) techniques were used to characterise fullerene. The sizes of the synthesised fullerene ranged from
48.20 nm to 73 nm. The EDX technique was used to determine the amounts of elements in a component, thereby
revealing the formation of fullerene. The produced fullerene was evaluated as a gas sensor for H2S and NO2 gases
at various temperatures and time intervals. The sensitivity of the gas sensor decreased with the increased
operating temperature reaching 150 ◦C. Then, the sensitivity increased as the temperature increased. The
maximum gas sensitivities for NO2 and H2S were 72.86% at 25 ◦C and 75.89% at 200 ◦C, respectively.
Description
A novel preparation method of fullerene involves synthesizing high-purity fullerenes through advanced chemical processes, enhancing their stability and surface properties. This method enables fullerenes to effectively detect hazardous gases like hydrogen sulfide (H2S) and nitrogen dioxide (NO2), showcasing their potential as sensitive, selective materials for environmental monitoring and safety applications
