P‐NiFe2O4/N‐doped carbon nanotubes/NiFe multi‐phase heterojunctions for overall water splitting and urea electrolysis

The design and construction of highly efficient electrocatalysts for overall water splitting and urea electrolysis are significantly important for promoting energy conversion and realizing green hydrogen production. In this work, we constructed a multi-phase heterojunction through a simple hydrothermal and phosphorization process. The P-doped NiFe
