A review of recent modification strategies of TiO2-based photoanodes for efficient photoelectrochemical water splitting performance

To address concerns about greenhouse gas emissions and sea level rise brought on by global climate change, hydrogen (H2) has the capacity to substitute fossil fuels as a carbon-free source of energy. The most reliable method of producing H2 is photoelectrochemical (PEC) water splitting, which uses w...
