The development of macrostructured catalysts for remediation processes is a key step towards the sustainability of multi-phase environmental systems,such as the catalytic reduction of inorganic contaminants.The advances towards practical applications faces great challenges regarding the availability of active centers on catalysts surface.To improve the catalytic activity of macrostructured bimetallic catalysts,it is crucial to understand which are the properties that most influence the catalytic activity of materials deposited on macrostructured supports.This work presents a systematic study on the design of macrostructured bimetallic catalysts with enhanced catalytic activity and selectivity.These materials were tested for selective NO3 conversion to N2.The adoption of different synthesis methodologies allowed a higher metal-metal interaction,which is an important property influencing the efficiency of the bimetallic catalyst.Metal phase distribution through coating layers proved to be a key-step for the synthesis of more active and N2 selective structured catalysts.
