Green chemistry is greatly advanced by catalytic converters, which also have important technological ramifications for the fight against pollution in the environment. These devices, which are often made of metals like palladium and platinum, are essential in catalyzing the conversion of dangerous pollutants released by internal combustion engines into less dangerous ones. Catalytic converters support the ideas of green chemistry by speeding up chemical reactions without using up any energy and balancing advancement in technology with environmental responsibility.
