New materials for oxygen evolution reaction (OER) electro-Mn, Ni, Co) towards OER in basic conditions. Our results showed catalysts in alkaline conditions have been highly investigated in that Ni0.5Mn0.5WO4 is a promising electrocatalyst, exhibiting ease recent years for the advancement of water splitting. However, of preparation, stability over the course of our experiments, and questions such as the lack of stability and the use of noble OER activity comparable to the standard iridium oxide. This metals as electrocatalysts still need to be addressed. In this study highlights the potential of wolframite tungsten-based study, we report the synthesis and electrocatalytic properties of materials as a new class of electrocatalysts for OER in alkaline a series of wolframite tungsten-based materials (MWO4, M=Fe, conditions.
