    Abstract: A production method of low dimensional nano-material comprises steps of: introducing a layered material; adding an intercalating agent into the layered material; and exfoliating the layered material by ball-milling to form the low dimensional material. Mechanochemical approaches for low dimensional nano-material like graphene quantum dots synthesis offer a promise of new reaction pathways, and greener and more efficient syntheses, making them potential approaches for low cost production.

    Abstract: Provided is a method for producing a modified graphene, comprising the steps of intercalating or inserting a mixture of intercalating agents in a spacing between interlayers of carbon substrates or between carbon substrates, whereby the binding force between the interlayers of the carbon substrates or between the carbon substrates is weaken; and then exfoliating the pretreated carbon substrates to form the modified graphene. Upon environmental friendly purpose, the method according to the present invention is useful for reducing the total amount of strong acid. Therefore, the amount of the generated oxygen-containing functional groups attached on the modified graphene is modulated to avoid defects and maintain a yield over 80%.

    Abstract: A nano-catalysts synthesis method comprises steps of: using a microplasma device to perform a microplasma treatment on a precursor solution; and purifying the precursor solution after the microplasma treatment to obtain the nano-catalysts. The microplasma has a plasma size smaller than one millimeter on at least one dimension. The precursor solution comprises a precursor and a solvent. The present invention can achieve a nano-catalysts producing method at room temperature with high efficiency and yield rate through a simple and rapid process using extremely low amount of acid or alkali solvent without introducing any toxic solvents.

    Abstract: The present invention provides a microplasma device and system thereof. The microplasma device comprises a reaction tank carrying with a reaction solution. A nanomaterial and its precursors are contained in the reaction solution. A first electrode is at least partially immersed in the reaction solution. A second electrode comprises a microplasma array component to eject microplasma array to the surface of the reaction solution. A power source is electrically connected between the first electrode and the second electrode. The present invention provides a novel microplasma array device to produce nanomaterial with increased yield rate. The microplasma array device can be multiplied by adding the outlet of the microplasma as desired to produce nanomaterial including but not limited to nano-metal particles, carbon quantum dots, silicon quantum dots and plasma-activated water with higher yield rate.
