Eco-Friendly Synthesis of Porous Molybdenum Carbide Nanomaterials for Advanced Electrochemical Sensing Applications

AbstractA highly stable and electrochemically active porous molybdenum carbide (PMC) has been synthesized from agricultural waste by carburization of bagasse under inert conditions. The surface area and porous structure of the resulting PMCs can be tuned by varying the synthesis conditions. The PMCs obtained have been characterized via XRD, XPS, SEM, and gas physisorption techniques. The final PMC materials are highly crystalline with nanoscale porosity and with an active surface area of up to 717 m2.g−1. This work unlocks a promising avenue for developing highly active electrochemical nanomaterials using green synthesis, potentially eliminating the need for noble metals. The results demonstrate a six‐fold increase in the electrochemical signal.
