Synergetic tuning charge dynamics and potentials of Ag3PO4 photocatalysts with boosting activity and stability by facile in-situ fluorination

Bifunctional S-scheme g-C3N4/Bi/BiVO4 hybrid photocatalysts toward artificial carbon cycling

“…It was supposed that a portion of Bi nanoparticles located at the interface of g-C3N4 and BiVO4 acted as an electron bridge, promoting the interfacial charge transfer. EIS analysis is a powerful tool to study the electrochemical charge transfer behavior at high frequency [3,11]. Fig.…”

“…In particular, the excessive emission of some persistent organic pollutants and volatile organic compounds into environmental media threatens human health and the ecological balance. A variety of advanced environmental techniques, such as microbial decomposition, have been developed to remove these carbon-based pollutants from air and water, which attempt to convert toxic and harmful organic compounds into innocuous CO2 [1][2][3][4][5][6]. Nevertheless, CO2 itself is the major greenhouse gas in the atmosphere, and increasing emissions of CO2 overloads the self-purification capacity of the environment based on natural carbon cycling [7][8][9].…”

Evaluation of 2-(salicylideneimino) thiophenol and other Schiff bases as bronze corrosion inhibitors by electrochemical techniques and surface analysis

“…Again, in comparison to SITP sample, the SITP + P sample also showed slightly higher amounts of Cu(II) ions and S atoms involved in sulphate species. Finally, a limited but significant atomic percentage of phosphorus atoms ascribed to phosphates [64] in the film was detected, most likely connected to the surface precipitation of Cu(II) phosphates at film defects where the concentration of dissolved Cu(II) ion was higher. This mechanism of defect healing may have been present in the film since the beginning of the immersion.…”

Continuously Improved Photocatalytic Performance of Zn2SnO4/SnO2/Cu2O Composites by Structural Modulation and Band Alignment Modification

“…Trapping experiments were devised to reveal what active species would dominate the photodegradation reaction process in presence of ZSC1.5 photocatalyst. According to previous reports [46,47], four scavengers of benzoquinone (BZQ 2 mmol L −1 ), sodium oxalate (SO, 4 mmol L −1 ), tert-butyl-alcohol (t-BuOH, 2 mmol L −1 ), and FeSO 4 -EDTA (FS-EDTA, 0.2 mmol L −1 ) were individually put into the system to capture the active species of •O 2 − , h + , •OH and H 2 O 2 . The variation of photodegradation rate upon exposure to different scavengers is presented in Figure 9.…”
