What does this research mean for the field?

Reduced graphene oxide (rGO) serves as an effective and stable support for both noble (Pt) and non-noble (Ni) metal catalysts in volatile organic compound oxidation, with Pt/rGO achieving significantly higher toluene conversion efficiency than Ni/rGO. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

The study aims to compare the effectiveness of Pt and Ni catalysts supported on reduced graphene oxide in oxidizing toluene.

Synthesis of reduced graphene oxide using modified Hummers oxidation and thermal reduction.
Preparation of Pt/rGO and Ni/rGO catalysts through wet impregnation with 1 wt% Pt and 10 wt% Ni, respectively.
Characterization of the catalysts using multiple techniques including XRD, SEM-EDS, and BET.
Pt/rGO achieved 99% conversion of toluene at 400 °C with T 50 ≈ 255 °C.
Ni/rGO reached only 55% conversion at 400 °C, highlighting the superiority of Pt.
The study confirms stable operation with CO 2 as the sole carbon product over time.
