Mo₂C उत्प्रेरक इलेक्ट्रोलिसिस में गतिशील पुनर्निर्माण दर्शाता है, हरा हाइड्रोजन को बढ़ावा देता है – MoS&T

Key Insight

गतिशील Mo₂C उत्प्रेरक पुनःडिज़ाइन हरा‑हाइड्रोजन लागत को कम कर सकता है, जिससे भारत के स्वच्छ‑ऊर्जा लक्ष्य सुदृढ़ होते हैं।

Key Facts

1. Mo₂C (molybdenum carbide) is an earth‑abundant, low‑cost electrocatalyst for hydrogen evolution.
2. In situ X‑ray absorption spectroscopy (XAS) and Raman spectroscopy showed Mo₂C forms oxygen‑deficient MoOₓ domains during electrolysis.
3. The MoOₓ domains act as the true active sites, giving higher hydrogen‑generation rates and better long‑term stability.
4. A Mo/Mo₂C heterostructure oxidises quickly, releasing soluble molybdate ions and losing activity.
5. The study, published in *Material Horizons* (2026), links atomic‑scale reconstruction to improved electrocatalytic performance.
6. Dynamic reconstruction is a controllable, reversible change that enhances both activity and durability of the catalyst.
7. The findings support India’s National Hydrogen Mission and the goal of scaling green hydrogen for transport and industry.

Background

Green hydrogen, produced by water electrolysis using renewable power, is central to India's energy security and climate commitments. Understanding how catalysts transform under reaction conditions helps overcome the twin challenges of cost and durability in large‑scale hydrogen production, a key focus of GS‑3 (Science & Technology).
