Researchers develop new catalyst which converts seawater into hydrogen

Researchers from the Pacific Northwest National Laboratory (PNNL), alongside collaborators from Oregon State University (OSU), have tested a catalyst which converts wastewater and seawater into hydrogen.

The molybdenum-phosphide (MoP) catalyst was tested with wastewater in a small reactor called a microbial electrolysis cell (MEC). In comparison to related studies, the MoP catalyst produced hydrogen fast times faster than other non-platinum catalysts.

“If you can produce hydrogen from seawater, the resource pool is pretty much unlimited,” said Yugan Shao, Material Scientist at PNNL and catalyst research leader.

Expanding on the MoP catalyst research, PNNL researchers then investigated the catalyst for use in MECs. The team began with the MoP combination due to its affinity for activating, or separating, water molecules.
