Recently, platinum-containing core-shell structures
with tunable magnetic and catalytic properties have attracted
intensive attentions and offered a wide range of applications. To
date, their synthetic routes are mostly based on galvanic
replacement, co-reduction, thermal decomposition and seed-mediated
method. But the detailed formation mechanisms of core-shell
structures in solution, especially, at gas-liquid interface are
still not completely clear, which is mostly achieved based on post
reaction studies or ex situ characterizations. In this regard, it
is worthwhile but still very challenging to directly visualize the
complicated and delicate dynamic processes.
