Fabrication of WO3 photoanode decorated with Au nanoplates and its enhanced photoelectrochemical properties

Ultrasonic-assisted synthesis of magnetic recyclable Fe3O4/rice husk biochar based photocatalysts for ciprofloxacin photodegradation in aqueous solution

“…Typically, the semicircle diameter in the high frequency region reected the charge transfer resistance between the electrode and the electrolyte. [34][35][36] Thus, these results clearly elucidated more effective separation of photogenerated electron-hole pairs and accelerated interfacial charge transfer from UFBP5 to reaction molecules than that from Fe 3 O 4 . Besides, the intermediates formed during the photodegradation of CIP by UFBP5 were determined by LC/MS analysis (Fig.…”

Hydrothermal construction of WO3·0.33H2O/g-C3N4 nanocomposites with enhanced adsorption and photocatalytic activity

“…1,2 Although the most widely used semiconductor TiO 2 has good redox ability, its wide band gap (3.2 eV) results in limited light absorption that can only be excited by ultraviolet light. 3 In order to enhance the utilization of solar light, it is necessary to develop visible-light-driven photocatalysts with a relatively narrow band gap.…”

Silver nanoparticles decorated a hybrid of PANI/MoS2 and PANI/WO3 as potential catalysts for direct photoelectrochemical oxidation of glucose

“…In recent years, organic and inorganic semiconductors (i.e metal oxide, metal sulfides) and its hybrid materials have been widely used to develop effective photocatalytic systems. Among these materials, molybdenum sulfide (MoS2) and tungsten trioxide (WO3) have been extensively used in photo-assisted electrocatalytic processes [14][15] due to their low cost, good stability, and efficient separation of charged carriers photogenerated to enhance sensing activity. However, these two semiconductors have an extraordinary rate of electron-hole recombination, causing the reduction of their catalytic efficiency.…”
