General description
Application
- Effect of morphology properties of NiW catalysts on hydrodesulfurization for individual sulfur compounds in fluid catalytic cracking diesel: This research discusses the influence of ammonium metatungstate hydrate in the preparation of NiW catalysts, focusing on its role in hydrodesulfurization processes (X Tao et al., 2014).
- Preparation of quaternary tungsten bronze nanoparticles by a thermal decomposition of ammonium metatungstate with oleylamine: This study examines the decomposition pathways of ammonium metatungstate hydrate into metatungstate anions and their applications in creating tungsten bronze nanoparticles (J Choi et al., 2015).
