Dethroning electrocatalysts for hydrogen production with inexpensive alternative material

Iron-based bimetallic electrocatalysts may be key for hydrogen synthesis

16-Mar-2021

Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution. Thus, many scientists worldwide have their hopes placed on what they regard ...
