Morphology Control of Platinum Particles Grown on a Liquid Metal Interface

complex produces sparsely localized, patch-like Pt deposits. These distinct morphologies and deposition modes of Pt particles modulate interfacial stress, driving LM droplet evolution and divergent macroscopic transformations. In particular, the oxide layer formed on LM surfaces, together with Pt-catalyzed hydrogen evolution, was confirmed as a primary factor governing LM transformations across multiscale. Overall, this study deepens the fundamental understanding of LM-based GRR mechanisms and demonstrates a coordination-tuning strategy for designing noble-metal-coated LM heterostructures with tailored morphologies and spatial distributions, which could enable their use as reconfigurable functional materials in a broad range of applications.
