We demonstrate here a seed-directed synthesis (SDS) of Beta, Levyne, and Heulandite zeolites in the absence of organotemplates, where the seeds drive crystallization of the zeolites. Compared with conventional Beta synthesized in the presence of organic templates, Beta-SDS exhibits large textural parameters, stable Al species, and unprecedentedly high density of active sites, resulting in superior catalytic activity and selectivity for valuable products in catalysis.

Mn3O4nanoparticles supported by layered Ti3C2MXene displayed favorable electrochemical activity for oxygen reduction reaction and superb power density for zinc–air battery.

The ingenious surface and electronic structures endow the ultrathin wrinkle-free Pd4Cu1nanosheets with enhanced methanol oxidation performance.
