Visible light-sensitive photocatalyst was developed by combining n-type silicon (n-Si) and tungsten trioxide (WO 3 , n-Si/WO 3 ), yielding an ohmic contact in between. In this system, the ohmic contact acted as an electron-and-hole mediator for the transfer of electrons and holes in the conduction band (CB) of WO 3 and in the valence band (VB) of n-Si, respectively. Utilizing thus- constructed n-Si/WO 3 , the decomposition of 2-propanolto CO 2 via acetone was achieved under visible light irradiation, by the contribution of holes in the VB of WO 3 to decompose 2-propanol and the consumption of electrons in the CB of n-Si to reduce O 2 . The combination of p-type Si (p-Si) and WO 3 (p-Si/ WO 3 ), not the ohmic contact but the rectifying contact, was much less effective, compared to n-Si/WO 3 .
