Metal Phosphate/Phosphonates for Hydrogen Production and Storage

As a kind of green energy, hydrogen is an effective way to solve energy shortages, environmental pollution, and climate change. At present, the cost of hydrogen energy production and storage is high. Metal phosphide is expected to be the upstream main raw material to support the hydrogen economy instead of precious metals due to its low hydrogen overpotential, adjustable electronic structure, high conductivity, and low price. This chapter reviews the R&D status of metal phosphates/phosphonates as electrocatalysts, photocatalysts, biological starters, and thermochemical stabilizers in hydrogen energy preparation and storage technology, respectively. The progress of phosphorous-based fuel cells is also summarized. Finally, the application of metal phosphate/phosphonates in the related fields of hydrogen energy development has prospected. This chapter aims to provide technical support and theoretical reference for researchers and beginners in related industries.
