This invention discloses a conductive filter material and its preparation method. The conductive filter material includes a carrier, the surface of which has a conductive layer formed by conductive particles. In this invention, the conductive filter material can directly utilize its inherent properties to provide an environment conducive to electron donor and acceptor exchange by bacteria, allowing reducing and oxidizing substances to exchange electrons. This enables substances requiring electron exchange energy to undergo continuous biochemical reactions under the action of bacteria, thereby avoiding secondary chemical pollution from oxides or reducing agents required for biochemical treatment and reducing pollutant treatment costs. The conductive filter material of this invention can be applied to biochemical treatment in various scenarios, with a wide range of applications. In this invention, cable bacteria can be used as the main bacteria in the biochemical reaction. Due to the conductivity of the conductive filter material surface, cable bacteria can be cultured, multiplied, and attached to the conductive filter material surface in large quantities, increasing the number of cable bacteria and thus improving biochemical efficiency.

This invention discloses a functionalized MXene-supported metal oxide catalytic material, its preparation method, and its applications. The preparation method includes: fully contacting a pretreated metal substrate with a liquid-phase system containing MXene and metal ions and reacting at high temperature, followed by annealing in air to obtain the MXene-supported metal oxide material; and then subjecting it to electrochemical or chemical treatment to obtain the functionalized MXene-supported metal oxide catalytic material. In the functionalized MXene-supported metal oxide catalytic material of this invention, electron transfer occurs between the functionalized MXene and the metal oxide, promoting the formation of more active sites in the metal oxide that are conducive to catalyst-reactant electron exchange, thereby improving the activity of the oxygen evolution reaction (OER). Simultaneously, the functionalized MXene has abundant surface groups, which can generate strong chemical interactions with the metal oxide, improving the stability of the metal oxide in acidic media.

Electron exchangers are placed in the conversion cell and divide it into cathode gas chamber, liquid conversion solution chamber filled with a multiple track injection liquid controller, and anode gas chamber. Voltage is applied to the electron exchangers to convert the liquid conversion solution to gases, and gases are released directly to the gas chambers. On the surfaces of the single sheets of the multiple track injection liquid controller, there are many tracks and puncture channels that are designed by critical surface calculations, and manufactured with a precision technology. A computing engine connected to the cloud is responsible for artificial intelligence calculations, and it controls valves, sensors, servo motors, and enhance gas flow devices. In producing the same amount of final gases, our method is energy efficient.
