LaF3 Nanosheet-induced Epitaxial Growth: Hollow (Co, Ni)2P/LaF3 Nanotube Arrays Built by Porous Heterojunction Walls Grown on Ni Foam as Active Electrocatalyst for Hydrogen Evolution Reaction.

Free-standing (Co, Ni)2P/LaF3 hollow nanotube arrays are directly grown on Ni foam (NF) (denoted as (Co, Ni)2P–La4/NF, where “4” refers to 4 g L–1 of La3+ in the starting material), which exhibits ...
