Effect of copper doping on the performance of electrochemical hydrogen storage ofLaCoO۳ nano-perovskites

Here, the LaCoO۳ and ۵% Cu-LaCoO۳ nano-perovskites were synthesized using the sol-gel method. Theelectrochemical results indicate that the presence of Cu۲+ in LaCoO۳ leads to an increase in the hydrogen storagecapacity, which is due to the positive effect of lattice distortion on the hydrogen adsorption and desorptionprocesses.
