March 25, 2010, at the 239th National Meeting of the American Chemical Society, Tongxiang Fan, and his colleagues, Di zhang, and Han Zhou from State Key Lab of Matrix Composites at Shanghai Jiaotong University, reported a novel design to increase the efficiency of utilizing solar energy to catalyze water into hydrogen fuel. Inspired from the structure of leaves, Fan's group have made Artificial Inorganic Leaf (AIL) with TiO2 increasing the efficiency more than 30 times that of conventional TiO2 catalysis.
