Highly efficient AgBr/BiVO4 photoanode for photocatalytic fuel cell

BiOBr/Bi5O7I/TiO2/Ti Photoanode Assembled Visible Light Responsive Photocatalytic Fuel Cell for Efficient Rhodamine B Degradation and Stable Electricity Generation

“…Studies have shown that the performance of PFC mainly depends on the performance of the electrode, especially the photoanode. [3,4] Therefore, the design of efficient and stable photoanode has become a research hotspot in this field. TiO 2 is a largely studied semiconductor material due to its stability, [5] strong oxidation power, [6] nontoxicity and low cost.…”

Carbon Nanotubes Incorporated Z-Scheme Assembly of AgBr/TiO2 for Photocatalytic Hydrogen Production under Visible Light Irradiations

“…This will help to produce greater number of photoelectrons and eventually yield of H 2 production. Moreover, the indirect bandgap energy of AgBr is 2.60 eV which helped to improve the optical response and excitation of photogenerated electrons from valence band (VB) to the conduction band (CB) in AgBr/CNTs/TiO 2 [26,27]. Thus, improved UV-Vis spectrum of AgBr/bCNTs/TiO 2 can be regarded as a superposition of AgBr and bCNTs/TiO 2 optical absorption spectra.…”

Self-CO2 Recycling Photocatalytic Fuel Cell for Enhancing Degradation of Pollutants and Production of Carbon-Neutral Fuel

“…13−15 Recently, wastewater degradation has been significantly improved by increasing the light energy utilization and catalytic activity of photocatalysts, 16,17 as well as developing new photocatalyst. 18 Although the reaction conditions for wastewater treatment using photocatalytic technology are mild, highly efficient, and nontoxic, CO 2 as the final product is directly released into the atmosphere in various wastewater treatment processes, such as photocatalytic technology, electrochemical technology, and microbial technology. 19,20 Assuming that the chemical oxygen demand (COD) of wastewater is 1000 mg L −1 and all carbon is converted into CO 2 , it can be calculated that about 15 000 t of CO 2 will be released into the atmosphere per 1000 t of wastewater.…”

“…With the development of wastewater treatment technologies, photocatalysis has attracted increasing attention because it can directly use solar energy to degrade refractory substrates and toxic substrates and treat wastewater thoroughly. − Photocatalysis can produce photogenerated carriers (photogenerated holes and photogenerated electrons) under the irradiation of sunlight on photocatalytic semiconductors, such as TiO 2 . The photogenerated holes oxidize H 2 O/OH – to produce hydroxyl radicals with strong oxidization to mineralize organic matter in the wastewater into CO 2 . − Recently, wastewater degradation has been significantly improved by increasing the light energy utilization and catalytic activity of photocatalysts, , as well as developing new photocatalyst …”
