Enhanced electrochemical oxidation of organic pollutants by boron-doped diamond based on porous titanium

Electrochemical Oxidation of 6:2 Polyfluoroalkyl Phosphate Diester—Simulation of Transformation Pathways and Reaction Kinetics with Hydroxyl Radicals

“…TPA was used as a • OH probe since it was shown to react selectively with • OH during EO, − and it was not directly degraded on the BDD electrode surface . The steady-state • OH concentration [ • OH] ss in mol/L was calculated for each experiment according to eq where k obs,TPA is the pseudo-first-order rate constant in s –1 and k • OH,TPA = 4.4 × 10 9 M –1 s –1 is the bimolecular reaction constant of TPA with • OH .…”

Nanostructured electrodes for electrocatalytic advanced oxidation processes: From materials preparation to mechanisms understanding and wastewater treatment applications

“…17c) [198]. The different utilization efficiency of porous electrode surface led to discrepancy between promotion of current efficiency and enhancement of • OH [203]. On the other hand, the current efficiency of porous Ti/BDD was smaller than that of plate anode because the surface could not be exploited completely in a mass transport control situation (Fig.…”

α(β)-PbO2 doped with Co3O4 and CNT porous composite materials with enhanced electrocatalytic activity for zinc electrowinning

“…L can be ascribed to the electrochemical system, 37 R s is the resistance of the solution, R ct is the polarization (or charge transfer) resistance for oxygen evolution and Q dl is a constant phase element related to the double-layer capacitance at the Ti |deposited composite| electrolyte. The combination of R ct and Q dl indicates the behavior of the interface between the deposited composite and electrolyte, which can be calculated by eqn (17). The combination of C f and R f (C f R f ) determines the properties of the oxide layer.…”

“…15 Comparative studies of the PbO 2 electrode on the plate-like and porous Ti substrates were reported, and higher electrocatalytic performance was obtained. 16,17 A porous Ti/SnO 2 -Sb 2 O 3 -CNT/PbO 2 electrode was prepared by thermal decomposition and electrodeposition technology, in which PbO 2 coating covered the surface of porous Ti and formed a ne crystalline structure, possessing a longer service life. 18 Another nanostructured 3D-Ti/Sb-SnO 2 -Gr electrode was fabricated by a fast-evaporation process, which achieved a great enhancement in the structure and electrochemical performance, especially in its electrocatalytic activity.…”
