Heterostructure formation of BiVO4 with different Bi compounds : role of the he...
Lopes, Osmando FerreiraFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Semiconductors employed as photocatalysts that can be activated by visible irradiation have attracted intense scientific interest due to their applications in heterogeneous photocatalysis. BiVO4 is a semiconductor with band gap value of 2.4 eV; however, this material exhibits poor photocatalytic activity mainly due to the rapid recombination of elec...
Síntese e caracterização de nanopartículas de Nb2O5 e estudo de suas propriedad...
Lopes, Osmando FerreiraUniversidade Federal de Minas Gerais; In this study, the use of niobium oxide nanoparticles (Nb2O5) prepared through the OPM method as photocatalysts for the degradation of pollutants was investigated, describing the dependence on hydrothermal parameters (temperature and time) in aspects such as morphology, structure, electronic properties, and how these factors influence the photocatalytic activity. The cataly...
