The present disclosure relates to a method for producing a molded article for water purification, including: preparing a natural mineral extract in an environmentally friendly manner; preparing a natural mineral-photocatalyst aqueous solution containing photocatalytic titanium dioxide (TiO) nanopowder dispersed in the natural mineral extract; and impregnating a plastic material with the natural mineral-photocatalyst aqueous solution under high-temperature and high-pressure conditions. The produced molded article may be installed on the surface of water or under water in lakes, reservoirs, ponds, rivers, aquariums, fish farms, swimming pools, water purification plants, and the like to adsorb and degrade organic substances, block the growth of bacteria and mold, and effectively reduce algal bloom.

Method for producing molded article for water purification

A semiconductor device includes first and second isolation regions, a first active region extending in a first direction between the first and second isolation regions, a first fin pattern on the first active region, nanowires on the first fin pattern, a gate electrode in a second direction on the first fin pattern, the gate electrode surrounding the nanowires, a first source/drain region on a side of the gate electrode, the first source/drain region being on the first active region and in contact with the nanowires, and a first source/drain contact on the first source/drain region, the first source/drain contact including a first portion on a top surface of the first source/drain region, and a second portion extending toward the first active region along a sidewall of the first source/drain region, an end of the first source/drain contact being on one of the first and second isolation regions.
