Gas Sensing of NiO-SCCNT Core–Shell Heterostructures

Raza, Muhammad Hamid; Movlaee, Kaveh; Leonardi, Salvatore Gianluca; Barsan, Nicolae; Neri, Giovanni; Pinna, Nicola

Hierarchical core–shell (C–S) heterostructures composed of a NiO shell deposited onto stacked‐cup carbon nanotubes (SCCNTs) are synthesized by atomic layer deposition (ALD). A film of NiO particles (0.80–21.8 nm in thickness) ...

SnO2-SiO2 1D Core-Shell Nanowires Heterostructures for Selective Hydrogen Sensing

Raza, Muhammad Hamid; Kaur, Navpreet; Comini, Elisabetta; Pinna, Nicola

SnO2 is one of the most employed n-type semiconducting metal oxide in chemo-resistive gas-sensing although it presents serious limitations due to a low selectivity. Herein, the authors introduce 1D SnO2-SiO2 core-shell ...
