Palladium NP-decorated CNT ropes as H2 chemiresistors. (a) TEM image of a CNT rope after deposition of Pd NPs. (b) (Inset) Pd NPs are highlighted by blue circles and a high resolution TEM image of a NP is shown in the main picture. (c) Histogram of the size of the Pd NPs for electrodepositions of various quantities of Pd in terms of the Coulombic loading (QPd). (d) Sensing responses to ppm levels of H2 for the different Coulombic loading of Pd nanoparticles. Reproduced with permission from Ref. 362. Copyright 2017, American Chemical Society.
