Latest Patents

One of Kwon's latest patents is a method for making an anatase type titanium dioxide photocatalyst. This innovative method allows for the preparation of a photocatalyst with a nano-level particle size without the need for high-temperature sintering processes. The process involves adding a titanium-based starting material to a selected solvent, followed by the addition of an acid or base catalyst. The resulting aqueous solution undergoes heat treatment to activate peptization, ultimately leading to the preparation of an anatase type titanium dioxide sol solution. This sol solution is then coated onto a support to complete the photocatalyst preparation.

Another notable patent is related to a gas sensor and the method for fabricating it. This invention includes a semiconductor substrate with a supporting layer that is electrically insulative and features a pattern groove. A heater is formed within this groove, and an electrically insulating layer is placed on top. An electrode is formed on this insulating layer, along with a sensing layer that detects target gases by measuring changes in electrical conductivity or resistance.
