How to Reduce GO to RGO in 3 Simple Steps

🎓 Introduction

If you’re looking to create reduced graphene oxide (RGO) in the lab — for research, prototyping, or education — here’s a simple, safe method using common lab materials.

🧪 Materials Needed

• Graphene oxide (GO) dispersion (2 mg/mL)

• Ascorbic acid (vitamin C) as a reducing agent

• Beaker, magnetic stirrer, water bath (70°C)

• Filter paper and drying oven

⚙️ Procedure

1. Add 10 wt% ascorbic acid to GO dispersion.

2. Stir at 70°C for 4 hours. The mixture gradually darkens to black.

3. Filter, wash, and dry to obtain RGO powder.

Optional: Add a drop of surfactant if targeting better dispersion post-reduction.

🔍 Notes

• Final RGO can be redispersed in water, ethanol, or polar solvents.

• Reduction extent can be confirmed via UV-Vis or Raman spectroscopy.
