In-Depth Information
Non-pollution, non-residue, environmental friendly, no harm to human health,
ecological safety and efficient, renewable functions of nano-TiO
2
determine its
broad and wide application in the future in sustainable agriculture. However,
in order to increase the photocatalytic efficiency, coating technique of nano-
TiO2 should be improved, and carrier selection and influence factor study
should be further explored. In addition, two keys for successes are (1) the
utilization of nanosized TiO
2
photocatalyst powders dispersed on substrates
with extremely large surface areas, and (2) spreading them on the ground
widely to collect sunlight. Because the concentrations of environmental
pollutants are low in general, the UV light contained in sunlight is sufficiently
strong to decompose them by TiO
2
photocatalysis, if we can collect the light
from a broad area [18].
