QuantumCat is a South Korean deep-tech materials company known as the first to commercialize gold nanocatalysts, holding gold nanoparticles inside proprietary silica nanocages so they keep their catalytic activity at room temperature. Its catalysts decompose carbon monoxide, volatile organic compounds and fluorinated greenhouse gases without extra heating, serving semiconductor emissions abatement, industrial and appliance odor control, and hydrogen and energy applications. Founded in 2019 in Daejeon by KAIST-trained physicist Kang Shin-hyun, the company runs its own mass-production line and supplies major Korean industrial and consumer-electronics partners.
