Cu-Mn and Cu-Ce supported over agro-based carbons: Characteristics and NOx adsorption study

As there is an urgent need for cheaper and sustainable resources for selective catalytic reduction catalyst, this study determined the potential, in terms of the catalyst characteristics and NOx adsorption, of coconut shell (CSAC) and palm kernel shell activated carbons (PSAC) to be used as precurso...
