LiNbO3 Coating on Concrete Surface: A New and Environmentally Friendly Route for Artificial Photosynthesis by Ranjit K. Nath, M. F. M. Zain, Abdul Amir H. Kadhum

“…In these research photoassisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using a photocatalyst, LiNbO3, coated on concrete surface under illumination of UV-visible or sunlight and showed that LiNbO3 achieved high conversion of CO2 into products despite the low levels of band-gap light available. The high reaction efficiency of LiNbO3 is explained by its strong remnant polarization (70 µC/cm2), allowing a longer lifetime of photoinduced carriers as well as an alternative reaction pathway. …”
