Electrospun carbon nano-felt surface-attached with Pd nanoparticles for hydrogen sensing application

► Electrospun carbon nano-felt surface-attached with Pd nanoparticles was prepared. ► The nano-felt was mechanically flexible/resilient. ► The resistance of the nano-felt varied upon exposure to H2. ► The nano-felt could be a material of choice for gas- and/or bio-sensors.
