Aether Catalyst Solutions, Inc. announced that it has filed a U.S. Provisional Patent Application entitled "MIXED METAL OXIDE CATALYST COMPOSITIONS AND PROCESSES FOR THE PRODUCTION THEREOF". Modern catalytic converters are often comprised of many chemistries, sometimes in several locations, all working in harmony to clean the exhaust gasses of vehicles. The key components of the catalyst chemistries are precious metals often referred to as Platinum Group Metals (PGMs). PGMs are very effective catalysts but are also exceptionally expensive due to their rarity and processing costs. Aether's catalyst formulation uses zero Platinum Group Metals, instead relying upon cost effective mixed metal oxides to provide the catalytic activity.
Given the cost and supply chain difficulties inherent in the acquisition and processing of PGMs, and the increasing geopolitical risks in the areas that mine them, it's no surprise that when faced with increased loadings of PGMs to meet rising emissions standards, OEMs are actively looking for alternatives.
