Laser scribing has been proposed as a fast and easy tool to reduce graphene oxide (GO) for a wide range of applications. Here, we investigate laser reduction of GO under a range of processing and material parameters, such as laser scan speed, number of laser passes, and material coverage. We use Raman spectroscopy for the characterization of the obtained materials. We demonstrate that laser scan speed is the most influential parameter, as a slower scan speed yields poor GO reduction. The number of laser passes is influential where the material coverage is higher, producing a significant improvement of GO reduction on a second pass. Material coverage is the least influential parameter, as it affects GO reduction only under restricted conditions.

We demonstrate a Si-mediated environmentally friendly reduction of graphene oxide (GO) and the fabrication of hybrid electrode materials with multiwall carbon nanotubes and nanofibers. The reduction of GO is facilitated by the nascent hydrogen generated by the reaction between Si and KOH. The overall process consumes 10 to 15 μm of Si each time and the same Si substrate can be used multiple times.
