Use butterfly wings to create green fuel

Butterflies have previously been classified as the most fragile materials in nature. However, Chinese scientists have recently discovered that the insect's wings are capable of increasing the yield of hydrogen - a green fuel - from the sun and water.

According to Dr. Tongxiang Fan of Shanghai Jiaotong University, one of the technologies to produce popular hydrogen fuel is to use sunlight to split water into hydrogen and oxygen atoms. Therefore, better light-absorbing materials will promote more efficient production. Meanwhile, according to this biologist, butterfly wings have long been discovered that there are countless structures that capture the tiny sunlight, which helps it heat up the body to wield overhead. Therefore, he thought that butterfly wings could become a useful material for hydrogen production.

Dr. Fan's crew started using Asian black butterflies Papilio Helenus to study, because black is considered to have the best absorption of light. Experts used its wing to produce titanium dioxide - a catalyst used in water separation reactions. Combining the production of titanium dioxide with specialized platinum nanoparticles, experts found that the efficiency of splitting water into hydrogen and oxygen of the sun actually doubled.
