The use of LiNbO3 photocatalyst in concrete material would be more beneficial since it can produce artificial photosynthesis. In these research photo-assisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using LiNbO3 coated on concrete surface under Illumination of UV-visible or sunlight. It shows that the use of LiNbO3 coating in concrete can achieve a good conversion of CO2 to expected products even though the low levels of band- gap light available. The high reaction efficiency of LiNbO3 is explained by its strong remnant polarization (70 [micro]C/[cm.sup.2]), allowing a longer lifetime of photo -induced carriers as well as an alternative reaction pathway. For the ease of usage and good photocatalytic efficiency, the research work done showed its potential application in pollution prevention.
