Recent advances of MoO3 based materials in energy catalysis: Applications in hydrogen evolution and oxygen evolution reactions

This work mainly focuses on the hydrogen evolution reaction and oxygen evolution reaction of nanostructured molybdenum trioxide-based materials for energy catalysis. MoO3 is an n-type wide bandgap semiconductor and has the ability to replace noble metal catalysts. Here we summarize the crystal structure and properties of nanostructured MoO3. The work also highlights the recent advancement in electrocatalytic hydrogen evolution reaction, photocatalytic hydrogen evolution reaction, photoelectrochemical hydrogen evolution reaction, electrocatalytic oxygen evolution reaction, and photoelectrochemical oxygen evolution reaction in MoO3 based materials.
