This review presents a comprehensive summary of the material-microorganism interface in microbial hybrid electrocatalysis systems. Microbial hybrid electrocatalysis has been developed to combine the advantages of inorganic electrocatalysis and microbial catalysis. However, electron transfer at the interfaces between microorganisms and materials is a very critical issue that affects the efficiency of the system.

Article Synopsis
  • - This study presents a novel system that combines inorganic light absorbers with living bacteria to create sustainable chemical reactions powered by solar energy.
  • - By using the electro-active bacterium MR-1 with a self-assembled CdS semiconductor, researchers show how light can enhance the bacteria's ability to transfer electrons and boost its catalytic processes.
  • - The results indicate a dramatic increase—711 times—in hydrogen production and other byproducts when MR-1 is paired with CdS under visible light, highlighting the effectiveness of this biotic-abiotic approach for future energy applications.

Hexavalent chromium (Cr(VI)) is a prominent toxic metal with significant adverse human health effects. Photocatalytic reduction of Cr(VI) to less-toxic trivalent chromium (Cr(III)) is a promising method for removing Cr(VI) from aquatic environments. However, this technique often suffers from electron-hole recombination of semiconductors and poor reduction efficiency.
