As promising precursor of functional carbon materials, coal tar pitch was selected as a precursor to prepare porous carbon nanosheets (PCN). Then MnO 2 was incorporated into porous carbon nanosheets to form MnO 2 @PCN by hydrothermal treatment. Both PCN and MnO 2 @PCN showed high specific surface areas (1605 m 2 /g and 836 m 2 /g) and nanosheets …
In our previous work [5], we reported that Al 4 C 3 provided a growth environment for graphene sheets from coal-tar pitch and decomposed at higher temperatures. Therefore, the Al 4 C 3 here, derived from the carbonization of coal-tar pitch and nano-Al 2 O 3, should be responsible for the formation of the GNs. Download : Download high-res image ...
The perspective highlights the shift of coal and other heavy carbonaceous materials (tar, pitch, and beyond) from combustion sources to low carbon emission applications ranging from joule heaters, supercapacitors, and strain sensors. Laser annealing and molecular dynamics simulations can guide the thermal upgrading of these materials, and machine learning …

Coal tar pitch is a solid product of coal tar distillation, accounting for about 50–60 wt% of HTCT (Liu et al., 2018). CTP is a complex mixture composed of PAHs and their derivatives (Zhou et al., 2011), in addition to small particles that are entrained from coking and concentrated in the pitch during tar distillation (Baron et al., 2016). 2.1.5
A typical coke-oven tar pitch has a C/H ratio of 1.6 to 1.9, while this study shows that early growth mesophase is typically more than 2.
