Highly-dispersed black SnO2-TiO2 nanocomposites were successfully synthesized by the sol-gel method using a Sn-POBC-Ti single-source precursor (POBC = p-carboxybenzaldehydeoxime), which adjusted the nanocomposite structure in molecular level. The SnO2 and TiO2 in the composites were highly dispersed due to the linkage of single source precursor; no TiO2 crystalline phase showed up when Sn:Ti≥1:1, and black SnO2-TiO2 nanocomposites can be achieved when Sn:Ti≤1:1,which was probably caused by the transformation from Sn2+-Ti4+ to Sn4+-Ti3+ . The black nanocomposite with Sn: Ti=1: 2 showed the best performance in methyl orange degradation, phenol degradation, as well as photovoltaic conversion in photoanode form. This can be contributed to the high surface area and the nano-heterojunction of SnO2-TiO2 caused by highly dispersed elements of single source precursor.
