Investigation of the Electrochemical Performance of Titanium-Based MXene Hybridisation with Rice Husk Ash (RHA) as an Anode Catalyst Support Material

MXenes possess unique features that are useful for broader industrial development. However, although many different compositions of have been discovered, little research has conducted on the optimal synthesis strategy producing best yield. Therefore, substantial work is performed synthesis’ structure and property relationship direct methanol fuel cell (DMFC) applications since successfully hybridised with rice husk ash (RHA). In this study, to produce titanium-based MXene, Ti3C2 nanopowders added matrix synthesise hybrid RHA/MXene composites (R-MX). Using weight percentages MXene (2 wt. % R-MX, 4 R-MX 6 R-MX), electrochemical properties obtained. Meanwhile, analysis undertaken investigate oxidation performance using Linear Sweep Voltammetry (LSV). The highest percentage composite, showed lowest Tafel slope (148 mV/dec) ionic exchange current density in same analysis. Moreover, incorporation into RHA produced good results from chronoamperometry (CA), R-6MX, showing retention rate 97.28%. Nyquist plot an increasing semicircle arc diameter at lower-frequency region, implying a lower interfacial charge resistance upon addition RHA. This outcome corresponded CA LSV findings, R-6MX remarkable terms having peak 0.9454 mA/cm2 Both these values show was able maintain high entire duration. maintained stable form some time, proving most stable, minimal corrosion reaction tolerance medium. study enabled evaluation possibility utilising low-cost, green material promote sustainability. novelty cheap source silica-based RHA, type waste material, incorporated through hybridisation processes.
