WebMolybdates were recognized in late 1990s as because of its simple, less toxicity, and less water solubility. It has general formula as M2 MoO 4, molybdate ions were generally available in solid and liquid phases. Calcium, zinc, and sodium molybdates have slight water solubility that makes them to use in corrosion-inhibiting coating system. WebJun 8, 2024 · Traditionally, iron molybdate catalysts have been synthesised by co-precipitating metal nitrate solutions using a base to yield precursors that are then calcined to form oxide catalysts with a low surface area (typically <10 m 2 g −1). 8,13,14 This preparation route is difficult to control leading to an inhomogeneous distribution of the ...
