नेशन हाइड्रोजन मिशन ऊर्जा के भारत -novel alloy-based catalyst for the efficient generation of green hydrogen

भारत की प्रगति के लिए, आत्मनिर्भर भारत बनाने के लिए भारत का Energy Independent होना अनिवार्य है।

भारत को ग्रीन हाइड्रोजन के उत्पादन और निर्यात का हब बनाना है।

भारत आज जो भी कार्य कर रहा है, उसमें सबसे बड़ा लक्ष्य है, जो भारत को क्वांटम जंप देने वाला है- वो है ग्रीन हाइड्रोजन का क्षेत्र। मैं आज तिरंगे की साक्षी में National Hydrogen Mission की घोषणा कर रहा हूं: PM @narendramodi

 

Key Highlights of the New High-Entropy Alloy (HEA) Catalyst for Hydrogen Production

• Innovation & Development:

  • A novel high-entropy alloy (HEA) catalyst named PtPdCoNiMn has been developed for efficient hydrogen production through water electrolysis.
  • Created by researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, under the Department of Science and Technology (DST), India.

• Material Composition & Design:

  • Consists of platinum (Pt), palladium (Pd), cobalt (Co), nickel (Ni), and manganese (Mn).
  • Selection of metals guided by Dr. Prashant Singh from AMES National Laboratory, USA.
  • HEAs contain multiple elements in near-equal concentrations, offering stability through entropic contributions.

• Synthesis Methods:

  • Electrodeposition: Optimized solvent choice and deposition potential at room temperature and atmospheric pressure.
  • Solvothermal Process: High-temperature, high-pressure chemical synthesis using carefully controlled solvents and reducing agents.
  • Enabled production of alloys in both single-phase and multi-phase forms.

• Performance & Efficiency:

  • Seven times less platinum used compared to commercial catalysts.
  • Higher catalytic efficiency than pure platinum, with minimal energy loss.
  • Durable and stable, maintaining performance for over 100 hours even in alkaline seawater.
  • Theoretical studies show optimal binding of reaction intermediates enhances efficiency.

• Practical Implications:

  • Potential to reduce reliance on expensive materials like platinum for clean energy production.
  • Offers a cost-effective, sustainable solution for hydrogen generation, supporting renewable energy technologies.

• Funding & Recognition:

  • Funded by India’s Anusandhan National Research Foundation (ANRF), administered by DST.
  • Research findings published in Advanced Functional Material and Small journals.
