摘要： Iron nanoparticles that are useful for constructing electrodes for lithium ion batteries and a method of making said particles is disclosed herein. The nanoparticles may include magnetite. The electrode may be constructed by centrifuging the nanoparticles to a current collector, such as a disc of copper, without the use of an extrinsic binder. The solvothermal method of making nanoparticles decreases the time of the procedure from about 24 hours to about 75 minutes. The method of making electrode decreases the complexity and number of steps compared to the conventional procedure to prepare an electrode, and eliminates the use of additives (binder and current enhancer) and toxic NMP solvents in the electrode preparation process.

摘要： Provided are a MoSxOy/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSxOy/carbon nanocomposite material, 2.5≤x≤3.1, 0.2≤y≤0.7, and the mass percent of MoSxOy is 5%-50% based on the total mass of the nanocomposite material. When the MoSxOy/carbon nanocomposite material is used as a catalyst for an electrocatalytic hydrogen evolution reaction, the current density is 150 mA/cm2 or more at an overpotential of 300 mV. The difference between this performance and the performance of a commercial 20% Pt/C catalyst is relatively small, or even equivalent; and this performance is far better than the catalytic performance of an existing MOS2 composite material. The MoSxOy/carbon nanocomposite material also has a good catalytic stability, and after 8,000 catalytic cycles, the current density thereof is only decreased by 3%, thus exhibiting a very good catalytic performance and cycle stability.

摘要： Methods and systems include supplying pulsed microwave radiation through a waveguide, where the microwave radiation propagates in a direction along the waveguide. A pressure within the waveguide is at least 0.1 atmosphere. A supply gas is provided at a first location along a length of the waveguide, a majority of the supply gas flowing in the direction of the microwave radiation propagation. A plasma is generated in the supply gas, and a process gas is added into the waveguide at a second location downstream from the first location. A majority of the process gas flows in the direction of the microwave propagation at a rate greater than 5 slm. An average energy of the plasma is controlled to convert the process gas into separated components, by controlling at least one of a pulsing frequency of the pulsed microwave radiation, and a duty cycle of the pulsed microwave radiation.
