  1. Synthesis of Novel Oxynitride Structures by Soft Chemical Routes Neal M. Abrams SUNY College of Environmental Science and Forestry, Syracuse, NY 13210 The efficient capture and conversion of solar energy requires a photocatalyst with a small bandgap able to absorb visible wavelengths. Oxynitrides offer advantages of being relatively stable and eco-friendly materials. Compared to binary nitrides, rare-earth metaloxynitridesare air stable, similar to their oxide counterpart. Because of this increased stability, the physical and chemical characteristics can be exploited under ambient conditions. Oxynitride synthesized by traditional (lower) and solvothermal (upper) pathways. We are developing toolbox of syntheticsolvothermal routes to oxynitridesmaterials. An impetus for this research is that oxynitrides show improved photocatalytic efficiency compared to the oxide analogs. Building upon the principle, we are developing a methodology for using natural (cellulosic) materials as biomimetictemplates for high-surface areaoxynitrides. 20 μm
