Surface tailoring and functionalization of an annealed TiO2 compact layer by H2SO4 acid was performed to improve the … layer with the mesoporous TiO2 film by Ti–O–Ti bonds formed by a followed heating process. Impedance measurement was further … used to investigate the enhancement mechanism, indicating the acid post treatment of the TiO2 compact layer reduces the …
