“…Semiconductors with photocatalytic activities driven by UV-vis light have been widely investigated [1][2][3][4][5][6][7][8][9][10]. Optical absorption energy is decided by band gap, which is followed by the release of holes and electrons from valence (VB) and conduction (CB) bands, respectively.…”

“…Some researchers claimed that doping with metal may decrease the band gap energy. However, metal doped can also act as a recombination center of electron and holes thus, reducing the photocatalytic activity (Larumbe et al 2015;Meng et al 2007). Some of the nonmetal doping TiO 2 have been explored such as nitrogen (Hou et al 2014;Ilinoiu et al 2013;Michael et al 2014), carbon (Park et al 2009;Wu et al 2013), sulphur (Liu & Chen 2008;Rengifo-Herrera et al 2009), boron (Ochiai et al 2010) and phosphorus (Xia et al 2014;Zheng et al 2010).…”

“…Por outro lado, a maioria das pesquisas relatam a síntese do TiO 2 pelo método Pechini com foco principalmente nas propriedades fotocatalíticas à base de nanopartículas [13,14] e soluções coloidais [15]. Porém, um estudo sobre a influência do teor das fases metaestáveis do TiO 2 sobre as propriedades ópticas e morfológicas precisa ser ainda melhor aprofundado.…”
