Light Delivers Hydrogen from Nonphotosynthetic Microorganisms

A team in Portugal has introduced a method for the sustainable conversion of solar energy into hydrogen, relying on biohybrid systems — combinations of nonphotosynthetic materials, bacteria, and semiconductor nanoparticles. The ability of those bacteria to produce high levels of hydrogen, paired with the cadmium sulfide nanoparticles’ efficiency in capturing light, initiated a direct energy transfer that the researchers said demonstrated a replicable and sustainable fuel-generation process. Many existing methods for the production of hydrogen are based on renewable energy, necessitating the continuous development of new and improved renewal options. Obstacles include high-cost materials and elements, as well as the...
