Using the precipitation method, we propose a new process for the preparation of high specific surface area and large pore volume ZnO nanoparticles in unconfined space with NH4HCO3 and ZnSO4·7H2O as ...

The nucleation and crystallization of Al and Fe phosphate phases directly from aqueous solutions were investigated experimentally in batch reactors at 50 to 200 °C and pH 1.6. The mineralogy, ...
