Mixed-phase TiO2 photocatalysts: Crystalline phase isolation and reconstruction, characterization and photocatalytic activity in the oxidation of 4-chlorophenol from aqueous effluents

Theoretical and experimental investigation into photoelectrocatalytic oxidation and reduction property of ZnFeTi mixed metal oxides

“…The removal rate of Cpl was enhanced remarkable with the increasing of voltage from 0.1 V to 0.5 V. About 70% of the Cpl was removed in 60 min under this reaction condition, and the reaction reached equivalence at a reaction time of 120 min, at which the removal rate was more than 99%. It is much efficient and effective than relevant results from other references [33][34][35]. While, further increasing the voltage of the photoelectrocatalysis resulted in little increment for removal rate.…”

“…According to some references [31][32][33][34][35], photocatalysis would generate highly active radicals such as hydroxide radicals ( • OH), superoxide radicals ( • O 2 -) and peroxide free radicals ( • OOH). • OH has the highest oxidation capacity among three radicals.…”

Visible-light Photocatalytic Degradation Effect of Sn-Contained Layered Double Hydroxides on4-Chlorophenol

“…图 3 为样品的紫外可见漫反射图谱。 根据 Kubelka-Munk 公式 [20] , 材料的禁带宽度可由下式计算: [21] , 并以(αhν) 2 对 hν 作图, 外推切线与横坐标 hν 的交点 即为禁带宽度。由此得到 ZnAl-LDHs、SnO 2 /ZnAl-LDH 和 ZnSn-LDHs 的禁带宽度分别为 3.05、2.94 [25][26]…”

Structural characterization of N-doped anatase–rutile mixed phase TiO2 nanorods assembled microspheres synthesized by simple sol–gel method

“…Most of the previous studies have focused on the preparation of single-phase TiO 2 nanostructures [1][2][3][4][5]. In addition, a recent study revealed that the combination of anatase-rutile mixed phase exhibited excellent photocatalytic activity compared to its single constituents [6][7][8][9][10]. The excellent photocatalytic activity is due to the synergy effect between anatase and rutile, which promotes interfacial electron transfer from rutile to anatase [7].…”
