Özet

Photocatalytic CO2 reduction has been extensively investigated in recent years as an environmentally friendly method to reduce CO2 emissions while producing more valuable chemicals. This work aims to assess the current state of the art in this technology by identifying key publications trends, recurring patterns in author keywords, and recent developments in materials and methods; some perspectives for the future are also provided by considering the challenges and advancements that may influence the upcoming works. Most of the efforts seem to be focused on the search for better semiconductors from new forms of traditional materials like TiO2 to relatively new materials like g-C3H4, MOFs, and perovskites. The use of nanostructures (such as nanoparticles, nanotubes, and nanosheets) has also gained more attention in recent years. It appears that the discovery and design of new semiconductors will continue to be critical in future works, suggesting that the use of artificial intelligence, especially recently developed generative AI tools, with remarkable search capacities and human-like inference capabilities, may make significant contributions to the field. It is also suggested that some standard testing and reporting protocols are necessary in the field to measure the actual performance and accurately assess the progress, which cannot be done with the current practice due to the uncertainties in experiments (especially those related to the light source), leading to non-comparable results in the literature.
