Green heterogeneous catalyst for biodiesel synthesis

The depletion of fossil fuel and global warming are major environmental concerns in recent decades and alternative sources of energy like solar, wind, hydro, biomass and even nuclear has been extensively studied by different scientists as potential solutions. However, one important problem associated with the running out of fossil fuel is normally overlooked i.e. the cease of chemical raw materials supply for plastics, medicine and other fine chemicals. Among all, biomass is the only hope that would harvest energy from sun with the cogeneration of important raw materials for our future. Also, due to its carbon neutrality, non toxicity, biodegradability and compatibility with the existing infrastructures for oil refinery and transportation system, biofuel has become a promising alternative as liquid transportation fuel.
