摘要

To investigate the possibility of interfacial charging, samples were annealed in order to soften the sample layer, causing the nanoparticles to coalesce. – Raman spectroscopy has shown that such annealing eliminates the 2-4 nm nanoparticle substructure. – This would eliminate the added surface area of the electrode without affecting its chemical composition. Therefore, any changes to electrode performance should be due to the reduced surface area. Samples of SnO_2 were annealed in a Lindberg tube furnace at approximately 500°C for 5 hours.
