Construction of high-efficient photoelectrocatalytic system by coupling with TiO 2 nano-tubes photoanode and active carbon/polytetrafluoroethylene cathode and its enhanced photoelectrocatalytic degradation of 2,4-dichlorophene and mechanism

Assessing the potential of biochar derived from sewage sludge for photoelectrode fabrication: methods, mechanisms, and conclusions

“…Although binders have been used to load powder onto conductive substrates, the addition of commonly used binders such as polyvinylpyrrolidone (PVP) and polytetrafluoroethylene (PTFE) usually negatively impacts the conductivity of photoelectrodes, while stability and uniformity remain to be improved. 16 Improvements to powder loading methods are necessary. The sol–gel method is a commonly used technique for preparing homogeneous catalysts.…”

Mechanism of UV‐driven Photoelectrocatalytic Degradation of Berberine Chloride Form Using the ESR Spin‐trapping Method

“…TiO 2 is widely employed in PC and PEC systems because of its low cost, long‐term chemical stability, photocorrosion resistance and nontoxicity . It has the ability to be prepared in various morphologies and produce ·OH . It is also an n‐type semiconductor with three main crystalline structures, rutile, anatase and brookite .…”

Two‐Dimensional Hollow TiO2 Nanoplates with Enhanced Photocatalytic Activity

“…[8,9] In most of their applications, the photocatalytic performances of TiO 2 particles are greatly depended on their crystal phase and structure. [10] In order to improve the photocatalytic performance, many kinds of structures of TiO 2 , including hierarchical nanospheres, [11] hollow spheres, [12] nanocubes, [13] nanowires, [14] nanotubes, [15] andn anosheets, [16] have been prepared. Among these structures, hollow structures have attracted more attention because of their higher specific surfacea reas, lower particled ensity,a nd better diffusion of dye molecules.…”
