Hydrogen Peroxide (H₂O₂)
| Aspect | Details |
|---|---|
| Chemical Formula | H₂O₂ (Simplest peroxide) |
| Properties | Colorless liquid, bitter taste, unstable (decomposes to H₂O + O₂ + heat), powerful oxidizer, eco-friendly degradation. |
| Natural Occurrence | Trace amounts in air, biological systems. |
| Household Use | Low concentrations (3-9%): Disinfectant, bleach, hair lightener. |
| Industrial Use | High concentrations: Textile/paper bleaching, rocket fuel, chemical synthesis, wastewater treatment. |
| Production Challenge | Conventional Anthraquinone Process: Energy-intensive, uses hazardous chemicals (e.g., palladium), generates waste. |
** Latest Breakthrough (2025)** -
- Technology: Mo-DHTA COF (Dimolybdenum Paddlewheel-Embedded Covalent Organic Framework).
- Process: Direct synthesis from water (H₂O) + sunlight (photocatalysis).
- Significance:
- Eco-friendly: Eliminates need for toxic solvents/H₂ gas.
- Energy-efficient: Uses solar energy instead of high-temperature/pressure.
- Sustainable: Aligns with India’s Green Hydrogen Mission & net-zero goals.
