Nowadays, public concern and the enforcement of environmental regulations by governments have made it necessary to develop versatile materials capable of efficiently eliminating a wide range of organic pollutants from both indoor and outdoor emissions. These pollutants contribute to photochemical smog and ground-level ozone and have raised severe concern owing to probable short- and long-term adverse health effects. In order to completely remove said emissions, numerous air purification systems based on catalysts, photocatalysts, adsorbents or ozone- promoted oxidation have been developed. However, most of these technologies have a limited efficiency in removing several pollutants under ambient conditions. In this context, Goldemar Solutions S.L. presents an innovative technology for the synthesis of gold nanocatalysts: Nanomaterials within the Subnanometer-Size Range. This discovery makes the gold nanocatalysts applicable for removing various harmful or undesirable compounds in sectors related to purification of air, providing the following potential uses thereof: i) complete removal of the cold-start emissions in automobile industry, ii) volatile organic compound (VOC) removal from indoor ambients or iii) air purification in enclosed environments such as submarines or aircrfats.
