Abstract: The present invention provides a novel biogenic photocatalyst particle based on microalgae culture, a preparation method thereof, and a use thereof. The biogenic photocatalyst particle according to the present invention exhibits high treatment efficiency in removing main organic pollutants (TCE, CF, and benzene) and nutrient salts (N and P). The biogenic photocatalyst particle according to the present invention has a complex pattern and a porous surface structure according to the distinctive species feature of each diatom itself and thus has a surface area in contact with the pollutants wider than that of the existing photocatalyst nano-particle, thereby exhibiting high efficiency in decomposing pollutants. Further, when treated with surface fixation, the biogenic photocatalyst particle can obtain economical effects by being recycled and can prevent environment contamination due to the outflow of nanoparticles resulting from the purification treatment. [Reference numerals] (AA) Pollutant removal rate at the time of removal with biogenic 20mg TiO_2;(BB) Removal rate (%/20mg TiO_2);(CC) Removal rate = amount of removed pollutants / initial concentration of pollutants * 100
