Facile preparation and characterization of MXene@Platinum nanocomposite for energy conversion applications

Abstract

The 2D transition metal carbide, MXene (MX - TixCxTx) and MX@Pt nanocomposites was prepared from MAX (Ti3AlC2) precursor. The effective nanocomposite (MXene/Pt) photocatalysts are prepared by facile water bath sonication and CVD tubular furnace thermal annealing treatment at 600 °C. The successfully prepared MAX into MXene (MX) flakes are also compared to structural conformation of MX@Pt nanocomposites through XRD results and revealed good crystalline diffracted peaks. The micro-RAMAN results explored with excelent connection of 106.49 and 612.78 cm−1. The FT-IR substantiation for Ti-C and Ti-O-C stretching for MXene (TixCxTx) functional groups confirm the MAX, MX, MX@Pt materials formation. The surface FE-SEM morphology explored MXene few-layer sheets with ‘Pt’ decorated (MX@Pt) nanocomposites. Further, FE-SEM with EDAX elemental characterization system confirm materials atomic percentage as ‘Ti’– 48.36 at. %, ‘C”– 48.63 at. % and platinum ‘Pt’– 3.01 at. %. Finally, MX@Pt nanocomposites explored to HER studies, which exhibited 165 mV to attain 10 mA/cm2 and it exhibited 477 mV overpotential to reach 100 mA/cm2. MX@Pt nanocomposites revealed for H2 and HER activity applications will demonstrate future potential H2 productions and water splitting applications.
