Energy generation and storage is one of the main challenges of the modern society due to the imminent shortage of fossil fuels and the environmental issues caused by them. The implementation of new technologies for alternative energy production depends on the costs of these technologies and of the associated catalysts. Thus, using cheap efficient photocatalysts and electrocatalysts to generate energy is essential for the establishment of economically viable sustainable energy production. Some of the most promising cheap photocatalysts are hematite, BiVO4, Cu2O, TiO2, Fe2TiO5, Sb2S3 and their modified versions containing dopants or transition metal cocatalysts, such as Co3O4, NiFeOx and MoS2, among others. Photoelectrocatalysis, in lieu of the heterogeneous photocatalysis, allows faster redox reactions at the solid/liquid interface and lower electron-hole recombination rates due to the applied external bias. Furthermore, the redox products generated at different photoelectrodes can be separately collected.
Different methodologies have been used in the attempt to reduce the costs of the catalysts and the processes for the production of fuels and other energy-related products. Some of the effective examples are electrodeposition techniques, sputtering deposition techniques and in-situ hydrothermal synthesis, among others. Many reports on the issue have been released in the literature, however a collection of papers on this theme is seldom published.
This Research Topic is devoted to studies focused on the reduction of the costs to develop photoelectrocatalyst materials and methods to generate sustainable energy. Related applications include photoelectrocatalytic hydrogen production, CO2 photoreduction, and biomass photoreforming to produce value-added chemicals and fuels.
This Research Topic welcomes submissions in the form of original research, review, mini-review, and perspective. Areas of interest include but are not limited to:
• Methodologies to synthesize low-cost transition-metal based electrocatalysts and photocatalysts;
• Recycled photoelectrocatalysts;
• Solar catalysis for fuels generation, such as photocatalytic hydrogen production, CO2 photoreduction, biomass photoreforming for value-added chemicals and fuels;
• Electrocatalytic water splitting。
Keywords:
Photoelectrocatalysts, low cost, hydrogen production, CO2 photoreduction, biomass photoreforming
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
