A series of applications of activated carbon and related materials treated with KOH (Potassium Hydroxide) in fields such as electronics and catalysis. However, there is currently no clear specific product line or technical definition of the "KOH Developer ENPD Series" in publicly available online information. Based on existing data, KOH is commonly used in the preparation of activated carbon materials to enhance their performance in high-performance devices such as supercapacitors and catalyst supports. For instance, it serves as a material treatment method in technologies related to precious metal catalysts and gallium nitride chargers.
