🌟 Graphitic Carbon Nitride–Decorated Cobalt Diselenide Composites for Highly Efficient Hydrogen Evolution Reaction

-

 


The Hydrogen Evolution Reaction (HER) is a cornerstone process in sustainable energy technologies, enabling the conversion of water into clean hydrogen fuel 🔋💧. Developing cost-effective, high-performance, and durable electrocatalysts is essential to replace precious metal catalysts like platinum. Transition-metal-based composites have emerged as promising alternatives due to their tunable electronic structures and abundant active sites.

🔹 2. Graphitic Carbon Nitride (g-C₃N₄): A Functional Support 🌿

Graphitic carbon nitride (g-C₃N₄) is a metal-free, polymeric semiconductor known for its high nitrogen content, chemical stability, and layered structure.
Key advantages include:

  • Rich nitrogen sites for electron donation ⚛️

  • Large surface area enhancing catalyst dispersion

  • Excellent corrosion resistance under electrochemical conditions

These features make g-C₃N₄ an ideal support material for boosting catalytic activity.

🔹 3. Cobalt Diselenide (CoSe₂): An Active HER Catalyst ⚙️

Cobalt diselenide (CoSe₂) is a transition metal chalcogenide with remarkable intrinsic catalytic properties.
Notable characteristics:

  • Metallic conductivity for fast charge transfer ⚡

  • Multiple exposed active edges

  • Favorable hydrogen adsorption energy

However, CoSe₂ alone may suffer from aggregation and limited long-term stability, which can reduce its performance.

🔹 4. Synergistic Effect of g-C₃N₄/CoSe₂ Composites 🤝

Decorating CoSe₂ with g-C₃N₄ creates a synergistic composite that overcomes individual limitations. The intimate interfacial contact enhances electron mobility, while g-C₃N₄ prevents CoSe₂ particle agglomeration.
Performance enhancements include:

  • Lower overpotential

  • Reduced Tafel slope 📉

  • Improved durability and stability

The strong electronic interaction between g-C₃N₄ and CoSe₂ optimizes hydrogen adsorption and accelerates reaction kinetics.

🔹 5. Significance and Future Outlook 🚀

Graphitic carbon nitride–decorated cobalt diselenide composites represent a next-generation, noble-metal-free electrocatalyst for HER. Their scalable synthesis, excellent efficiency, and long-term stability position them as key materials for green hydrogen production. Future research can further optimize morphology, interface engineering, and multi-element doping to unlock even higher catalytic performance 🌱⚡.

The Indian Space Research Organisation (ISRO) is set to make history by launching an American communications satellite. This is the first time an American company is using an Indian rocket for such a large and advanced satellite. The mission is expected to occur in February or March 2025. India cultural tours Background of the Mission Historically, ISRO has focused on launching small satellites from American manufacturers. The upcoming launch will be the first instance of a massive communications satellite being deployed by a US company from Indian soil. This initiative reflects the growing partnership between India and the United States in the field of space technology. The Role of AST SpaceMobile AST SpaceMobile, a Texas-based company, is expected to be the manufacturer of the satellite. The company has developed technology that allows users to make voice calls using standard smartphones. Unlike other satellite communication providers, AST SpaceMobile does not require users to purcha...

Kaveri Engine Ready for Inflight Testing

-
Image
India’s Gas Turbine Research Establishment (GTRE) has made advancements with the Kaveri engine, which is now ready for inflight testing, marking a very important moment in India’s pursuit of self-reliance in aerospace technology, particularly for unmanned aerial vehicles (UAVs). Background of the Kaveri Engine The Kaveri engine development began in the late 1980s to power the Tejas Light Combat Aircraft. Initial designs faced technical challenges, leading to a shift in focus towards a modified “dry” version suitable for UAVs. Technical Specifications The dry version of the Kaveri engine generates thrust between 49-51 kN. This thrust level is adequate for UAVs, such as the Ghatak stealth drone. Future enhancements aim to incorporate an afterburner, potentially increasing thrust to 73-75 kN for more demanding applications. Extensive testing has been conducted, including trials in both Russia and India. The engine has successfully passed critical ground and high-altitude tests, demonstrat...

Recent assessments reveal alarming statistics regarding freshwater biodiversity. A study conducted by the International Union for Conservation of Nature (IUCN) indicates that nearly 25 per cent of the 23,496 species examined are threatened with extinction. This analysis marks the urgent need for conservation efforts in critical habitats. Extinction Statistics The study identified 4,294 species at high risk of extinction, which equates to approximately 18.3 per cent of the total assessed. The majority of these species are found in biodiversity hotspots such as Lake Victoria, Lake Titicaca, Sri Lanka’s wet zone, and India’s Western Ghats. These areas are home to unique species that exist nowhere else on the planet. India food delivery Historical Context of Extinctions Since the year 1500, there have been 89 confirmed extinctions, with an additional 178 suspected. The United States, Mexico, and the Philippines have reported the highest numbers of extinctions among freshwater species. Nota...
