Surface engineered active Co3+ species in alkali doped Co3O4 spinel catalyst with superior O2 activation for efficient CO oxidation
Karthikeyan Gopalsamy,Sathishkannan Radhakrishnan,Sundaravel Balachandran,Prabhu Azhagapillai +3 more
TL;DR: In this article , Co3O4 and alkali metal-doped spinel materials were obtained by the co-precipitation method and employed as suitable catalysts for CO oxidation by calcining the precipitated hydroxides of Co at 300°C and 800°C (with and without the presence of water vapor) in the air atmosphere.

Twenty-five years after introduction of automotive catalysts: what next?
TL;DR: The union of catalysts and the automobile has been one of the greatest successes of heterogeneous catalysis over the last 25 years as mentioned in this paper, and there will be continued research and development activity focused also on downstream applications (i.e. exhaust emission aftertreatment), especially for fuelefficient, lean-burn vehicles, both diesel and spark-ignited.
