Photoelectrocatalytic-Enabled Flexible Polymeric Optoelectrodes
Background Photoelectrocatalytic processes (PECs) combine photocatalysis and electrochemical principles to enhance charge carrier generation and stability within nanomaterials (NMs). Nano-enabled PECs can be used for water purification or hydrogen production applications. Current PEC designs face challenges due to low energy efficiencies, because most...

High-Efficiency Photocatalytic Formate Production from Carbon Dioxide
Background Greenhouse gases (GHGs) trap heat and lead to global warming and other severe effects of climate change. Carbon dioxide (CO2) is the main source of GHG, and its capture before entering the atmosphere is an important mitigation approach. Captured CO2 from point-emission sources or via direct air capture (DAC) can be geologically sequestered...

High-Efficiency Photocatalytic H2O2 Production
Background Hydrogen peroxide (H2O2) is widely used for industrial synthesis of organic chemicals, advanced oxidation of drinking or wastewater, and surface disinfection of pathogens. Currently, ~95% of H2O2 production employs the energy- and chemical-intensive anthraquinone-oxidation process. Photocatalytic H2O2 production is an emerging alternative...
