The rational construction of efficient and low-cost electrocatalysts for the hydrogen evolution reaction (HER) is critical to seawater electrolysis. Herein, trimetallic heterostructured core-shell nanoboxes based on Prussian blue analogues (Ni-Co@Fe-Co PBA) were synthesized using an iterative coprecipitation strategy. same procedure was used preparation PBA core shell, with synthesis shell involving chemical etching during introduction ferrous ions. Due its unique structure composition,...
Abstract The authors report an ammonia‐assisted in situ cation‐exchange method for the synthesis of dodecagon N‐doped PdCoNi carbon‐based nanosheets (Pd‐e‐NiCo‐PBA‐C) and explore catalytic performance.

Quadruple perovskite oxides have received extensive attention in electronics and catalysis, owing to their cation-ordering structure intriguing physical properties. However, repertoires still remain limited. In particular, piezoelectricity from quadruple perovskites has been rarely reported due the frustrated symmetry-breaking transition A-site-ordered structures, disabling piezoelectric applications.
