- A team of scientists from India (Assam, Odisha), China, and the U.K. has developed a water-repellent catalyst that significantly reduces the cost of producing biodiesel.
- This spherical superhydrophobic activated carbon catalyst, designed to withstand water byproducts during biodiesel production, was detailed in the journal Advanced Functional Materials.
Biodiesel
- It is a renewable, biodegradable fuel made from vegetable oils, animal fats, and recycled cooking oil.
- It significantly reduces greenhouse gas emissions compared to conventional diesel.
- Biodiesel can be produced from diverse feedstocks like soybean oil and palm oil, offering flexibility in production.
- It is compatible with existing diesel engines, either as pure fuel (B100) or in blends (e.g., B20).
- Superhydrophobic catalysts mimic the water-repelling properties of natural surfaces like lotus leaves, preventing the poisoning of active sites by water.
- The novel catalyst is robust, highly effective, reusable, and derived from biomass, making it ecologically benign and affordable.
- This breakthrough could reduce the cost of biodiesel production, making it a more viable and sustainable energy option.
- The innovative catalyst enhances the efficiency, cost-effectiveness, and environmental friendliness of biodiesel production, paving the way for broader adoption and a greener future.
| Generation of Biodiesels | Input Material |
| First Generation | Edible vegetable oils (e.g., soybean, rapeseed, palm oil) |
| Second Generation | Non-edible oils (e.g., jatropha, castor bean), waste cooking oil, animal fats |
| Third Generation | Algae, microalgae, and other aquatic plants |
| Fourth Generation | Genetically engineered crops and microorganisms designed to produce biofuel directly |
