“…In the range of 340-450 °C, the weight loss (2.2%) was associated with thermal decomposition of TEOS and TBT [31]. [30,32,33]. Accordingly, the following reactions can be expressed as follows: …”

“…However, most of these semiconductor photocatalysts suffer from low separation efficiency of photogenerated electron-hole pairs, which will result in a poor photocatalytic performance, and photocorrosion makes these photocatalysts unstable and nearly unrecyclable either. To solve these problems, numerous attempts such as synthesizing various structures, doping with elements, coupling with other semiconductors, and supporting with other materials have been developed [7][8][9]. Among these methods, coupling with carbon materials such as CNT, C 3 N 4 and graphene is regarded as a promising method [10][11][12][13][14].…”

“…A proporção de anatase (FA) nas amostras foi calculada segundo a equação 1 [29], que relaciona a intensidade do pico mais característico das fases anatase (IA; 2θ = 25,3°) e rutilo (IR; 2θ = 27,4°). A partir dos valores da fração de anatase calculou-se a de rutio (F =1 F ) A identificação das fases foi realizada por comparação com os padrões do National Bureau of Standards (U. S.) e com difratogramas publicados na literatura para os óxidos de titânio (anatase, rutilo e brookita) [1,[20][21][22][23][30][31][32][33]. 1Análises termogravimétricas (TG) foram realizadas no analisador térmico simultâneo TGA-DTA (Shimadzu).…”

“…Nesse processo as fases anatase e rutilo do TiO 2 foram observadas após a pirólise do gel a 900 °C. O TiO 2 é o principal material usado em processos fotocatalíticos, especialmente para degradação de corantes em meio aquoso [1,[15][16][17][18][19][20][21][22][23]. Vários estudos mostram que a combinação do TiO 2 com o carbono melhora sua performance fotocatalítica.…”
