Visible light photocatalyst
Radiative transfer equation
In the present work the absorption (𝜅) and scattering (σ) coefficients were determined for NiFe2O4 nanoparticles in aqueous suspensions. The photocatalyst was previously synthetized by a modified Pechini method, measurements were carried out through UV/Visible spectroscopy, and experimental data were fitted with a new proposed model called 3-dim-3-dir. The resultant coefficients were used to solve the radiative transfer equation (RTE) using a discrete ordinated method (DOM) in order to determine the local volumetric rate of photon absorption (LVRPA) in a proposed reactor design model employing NiFe2O4 as photocatalyst.
