Research progress in nitrogen cycling driven by biohybrids constructed with photocatalytic materials

Abstract:

Nitrogen is an essential element for living organisms on Earth, and it is constantly recycled in the biosphere in different forms. A biohybrid constructed with photocatalytic materials is a new system produced in recent years, which combines photocatalytic materials with electroactive microorganisms, integrating the excellent light trapping performance of photocatalysts and the bioefficient catalytic capability. Therefore, it is of great significance to study how the system plays a role in nitrogen cycling and the related mechanisms. This paper introduces the microbial nitrogen cycling and the nitrogen cycling driven by biohybrids and details several types, advantages and disadvantages, and related mechanisms of electron transfer driven by biohybrids constructed with photocatalytic materials. Finally, this paper makes an outlook on the development prospects in this field from the natures and combinations of photocatalytic materials and microorganisms.
