Macroporous polypyrrole-TiO2 composites with improved photoactivity and electrochemical sensitivity.


Macroporous polypyrrole (PPy)-TiO2 composites were prepared by in situ oxidative polymerization of pyrrole in the macropores of TiO2. The formation mechanism of the PPy nanoparticles, including nucleation and further growth, was proposed by studying the particle growth process with increasing reaction time. The special growth process favors the formation of… (More)
