LaCr0.99M0.01O3 (where M = Ti, Fe, and Mo) nano perovskites: Band gap energy determination and cellulose conversion preliminary test

The prepared material was LaCr1-xMxO3 (M= Ti, Fe, and Mo) using pectin as an emulsifier and freeze drying and calcined at a temperature of 700°C. The promotion of electrons from the HOMO level (valence band) to the LUMO level (conductance band) is determined by the amount of gap energy required so that photocatalysis of the substrate occurs. The band gap energy results show that the 700°C calcined catalyst has the smallest Eb value, which is 2.6 eV. Furthermore, the photocatalytic conversion of nanocellulose showed that the conversion increased with the atomic size of the smaller dopant.
