Fabrication of multiwall carbon nanotube sheet based ...

2018-7-11 · Among these, carbon nanotube (CNT)-based sensors have been widely studied [10–12]. It is well known that when electron-donating or electron-accepting gas molecules adsorb/desorb onto/from the CNT surface, electron transfer takes place and leads to a resistance change in the CNT. This allows the CNT to work as a gas sensor.

Influence of Gd Doping on the Structure and ...

Gd‐doped TiO 2 −NT/SnO 2 −Sb (NT=nanotube) electrodes were prepared by using a solvothermal synthesis approach with a nano‐sized catalyst coating. Phenol degradation and total organic carbon (TOC) removal followed pseudo‐first‐order kinetics in the experimental range. A maximum rate was achieved by using a Gd doping ratio of 2 % (molar ratio based on Gd/Sn), which was 56.5 % and 68 ...
