“…Our result of chlorophyll decomposing to generate magnesium metal is in agreement with the previous reported work. [35] Previous research has demonstrated the potential of magnesium metal to reduce carbon monoxide and carbon dioxide to form graphene sheets, [17,22,36] but here magnesium metal has been replaced by chlorophyll from plants; the magnesium metal is an intermediate that is more safe and efficient. Hence this preparation method is obviously a significantly improvement.…”

“…Very recently researchers' attention and effort has focused on the preparation of graphene materials using different biomass resources for applications in super-capacitors, which provide a great opportunity to develop less costly and more efficient novel energy materials. [18][19][20][21][22][23][24] Our laboratory and others also published a method where graphene is produced through CO and CO 2 reduction with reduced chemicals of Al 2 S 3 [25] and magnesium powder (Mg). [26] Since then, we realized the possibility of using plant leaves where organic coordinated magnesium can serve to replace magnesium powder metal.…”

Graphene sheets were prepared by calcination of calcium carbonate with plant leaves under the protection of an argon gas atmosphere. This is an environmentally friendly approach to produce graphene. Calcium carbonate decomposes with the evolution of carbon dioxide at high temperature, which is reduced into graphene by the magnesium from plant leaves. The formation mechanism of graphene is discussed in detail. The synthesized graphene sheets were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman spectroscopy. Calcium carbonate and plant leaves are readily available and inexpensive natural resources, and this new methodology can be applied for large-scale graphene production in industry.

“…Nitrogen Adsorption/Desorption Analysis N 2 adsorption/desorption isotherms of N-doped WCBC powders were recorded by static volumetric method (also known as manometric method), which exhibited the features of type IV curve, as shown in Figure 4A (Thommes et al, 2015;Qin and Chen, 2017). Specifically, the adsorption volume steeply increased at the range of P/P 0 < 0.01 and an obvious hysteresis loop appeared at the range of P/P 0 > 0.45, indicating the co-existence of the micropores and mesopores (Qin and Chen, 2017). The pore size distribution plots were recorded from the desorption branch of the isotherms based on Barrett-Joyner-Halenda (BJH) model, as shown in Figure 4B.…”

As one of the common life garbages, about 4.5 trillion waste cigarette butts are produced and randomly discarded every year due to the addiction to the nicotine and the need of the social intercourse. Such a treatment would result in the waste of the resources and the environmental pollution if they weren't reasonably recycled in time. Herein, the waste cigarette butts were recycled in form of N-doped carbon powders with high economic value-added via one-step facile carbonization at 800 • C for 2 h in the inert N 2 atmosphere. The waste-cigarette-butts-derived black carbon powders were characterized by scanning electron microscope (SEM), N 2 adsorption/desorption, and X-ray photoelectron spectroscopy (XPS). Furthermore, the corresponding electrochemical performances as the anode in lithium ion battery (LIB) were also investigated by galvanostatic charge/discharge, cyclic voltammetry (CV), and alternating current (AC) impedance. The results suggested that the recycled N-doped waste cigarette butts carbon (WCBC) powders consisted of major carbon and minor residual N-containing and O-containing functional groups, and the corresponding specific surface area was about 1,285 m 2 •g −1. Furthermore, the reversible specific discharge capacity was about 528 mAh•g −1 for 100 cycles at 25 mA•g −1 and about 151 mAh•g −1 even at 2,000 mA•g −1 for 2,500 cycles. Additionally, full cell performances were also satisfactory, indicating high feasibility. N-doping effect (such as additional active sites and higher electronic conductivity) and the residual O-containing functional groups may be responsible for the satisfactory electrochemical performances, which offered good inspiration and strategy to develop the green energy and circular economy.
