Abstract

Abstract:

Since solar power was introduced into the microbial fuel cell (MFC) field, there is great interest in microbial electrochemical-photoelectrochemical synergetic systems used for electrogenesis, fuel production or environmental cleaning. Metal oxide is a common medium in solar power conversion. Research on interaction between microorganism and metal oxide is necessary to understand synergy mechanism or enhance efficiency. In this paper, various interactions between microorganism and metal oxide are summarized according to physical absorption, microbial weathering, microbial mining, photocatalytic sterilization and microbe-metal oxide synergistic effects, providing a reference for the construction of efficient microbial electrochemical-photoelectrochemical synergetic systems.

Key words: metal oxide, microorganism, catalysis, metal-oxide-microbe interaction, biofuel, nanomaterials
