Additionally, this materials chart can accelerate the design of new catalysts, since it indicates the regions of the materials space where high-performant materials are found. In particular, catalysts with high 𝑑 : ‰ values (regions shown in blue in Fig. ) are associated to high selectivity towards the formation of acrylic acid. From eq. 5, the pore volumes and the activation energy of conductivity are the key properties that impact the value of 𝑑 : ‰ . By increasing pore volumes and decreasing activation energy of conductivity, for instance, 𝑑 :
