Photobiocatalytic Hydrogen Production by Using Cyanobacteria Coupled with Nanoparticles of CdS and CdS/ZnS
Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Hydrogen can be produced by certain groups of microorganisms that possess functional nitrogenase and/or bidirectional hydrogenases. In particular, the potential of photobiological hydrogen production by oxygenic photosynthetic microbes has attracted significant interest. However, nitrogenase and hydrogenase are generally oxygen sensitive and require protective mechanisms to function in an aerobic extracellular environment. Here, we describe n-CdS coupled with cyanobacterium with the capacity to generate high levels of hydrogen under aerobic conditions for environmentally viable.
