Highly Efficient Nitrogen‐Fixing Microbial Hydrogel Device for Sustainable Solar Hydrogen Production (Adv. Mater. 52/2023)

Sustainable Solar Energy Conversion In article number 2306092, Wang Hee Lee, Taeghwan Hyeon, Yeong‐Jae Seok, Dae‐Hyeong Kim, and co‐workers present a microbial device, designed to operate at the air–water interface, facilitating concomitant supply of gaseous reactants, smooth capture of gaseous products, and efficient sunlight delivery. Efficient nitrogen fixation and hydrogen generation, low fabrication cost, and mechanical durability corroborate the potential of the floatable microbial device toward practical and sustainable solar energy conversion.
