“…3,18 Therefore, their high potential for catalytic applications is beyond all doubt. 15,[19][20][21] Despite the great potential of supraparticles, their applicability for catalysis in fixed-bed reactors is still limited because of their still too-small microscale sizes. In these reactors, particle (or pellet) sizes of at least 0.5 to 2 mm are required to avoid massive pressure drops as well as particle losses.…”
