Abstract

Disclosed are a carbon-based microorganism electronic diverter material and a preparation method and use thereof. The preparation method may include the following steps of (1) bringing a porous carbon material and dopamine to reaction to obtain a dopamine modified porous carbon material; and (2) bringing the dopamine modified porous carbon material and resazurin to reaction to obtain the carbon-based microorganism electronic diverter material. The carbon-based microorganism electronic diverter material prepared by the disclosure has a capability of storing charges, and is capable of intercepting electrons in a microorganism-driven reduction process of dissimilatory arsenic and iron, and remarkably reducing arsenic reduction and release in a rice field flooding process.
