Effect of active zinc oxide dispersion on reduced graphite oxide for hydrogen sulfide adsorption at mid-temperature

- ZnO/rGO was prepared using a microwave irradiation for H2S adsorption at 300 °C.
- The rGO prevents the aggregation of nano ZnO at 300 °C.
- ZnO/rGO sorbent keeps high H2S adsorption utilization at 300 °C, unlike pure ZnO.
- The presence of H2 increases ZnO utilization toward H2S adsorption at 300 °C.
- The presence of CO2 shows lower ZnO utilization toward H2S adsorption at 300 °C.
