Abstract Synthesis of core–shell nanostructures with magnetic core and zeolitic shell is an ongoing challenge. Herein, a strategy is presented for preparation of γ‐Fe2O3@mesoporous silica (mSiO2) core–shell nanoparticles containing ultrasmall

In this work, the effect of calcination temperature on the preparation of WOx catalysts supported on γ-Fe2O3@SiO2 core-shell nanostructure is reported. Powder XRD and Raman results evidenced that during calcination between 400 and 600°C, the SiO2 s

The activity of copper-doped hematite in the SCR with propane, in the presence of oxygen, was evaluated in this work. It was found that copper sulfate led to the production of solids with different specific surface areas depending on the amount of co

The aim of this work was to study the hydrothermal synthesis of Si and SiAlMCM-41 performed under both autogenic pressure and refluxing conditions. XRD data showed that the MCM-41 phase may be formed by both processes and that the synthesized materia
