Multiwall carbon nanotubes loaded with MoS2 quantum dots and MXene quantum dots: Non–Pt bifunctional catalyst for the methanol oxidation and oxygen reduction reactions in alkaline solution
Abstract
Abstract We synthesized a novel composite of multiwall carbon nanotubes (MWCNTs) decorated with MoS2 quantum dots (MoS2 QDs) and Ti3C2Tx QDs (denoted by MoS2QDs@Ti3C2TxQDs@MWCNTs), of which MoS2 QDs and Ti3C2Tx QDs were separately prepared by exfoliating MoS2 and Ti3C2Tx MXene nanosheets by the hydrothermal method. It showed that the as–prepared MoS2QDs@Ti3C2TxQDs@MMWCNTs composite was rich in functional groups and exhibited homogeneous nanotube nanostructure by coupling with good electrochemical activity. Of note, the MoS2QDs@Ti3C2TxQDs@MWCNTs composite exhibited outstanding bifunctional electrocatalytic performances for oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) in alkaline solution by combining the superior electrocatalytic activity of MoS2 QDs and Ti3C2Tx QDs and the excellent electrochemical performance of MWCNTs. The MoS2QDs@Ti3C2TxQDs@MMWCNTs catalyst exhibited a superior ORR activity to other non-Pt catalysts, giving a low Tafel slope (90 mV dec−1) and high half potential (E1/2, 0.75 V), which was close to those of the commercial Pt/C (20%) catalyst (Tafel slope of 89 mV dec−1, E1/2 of 0.80 V). Additionally, the MoS2QDs@Ti3C2TxQDs@MMWCNTs also possessed good electro–oxidation performance for methanol in alkaline solution, giving a maximum methanol oxidation current density at 2.2 V of 160 A·g−1. The results indicated that the combination of MoS2 and Ti3C2Tx QDs with MWCNTs can supply a potential for fabricating the bifunctional electrocatalysts for ORR and MOR.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
