Novel of Poly(triazine imide) Composite for Selective Photooxidation

Poly(triazine imide) is a non-metal semiconductor material with remarkable photocatalytic properties, which was successfully employed for selective photoreactions. Currently, pristine forms of semiconductors are inefficient and rarely used as such. Instead, various composites are being composed on their base in search of more efficient means for photo-activated processes, such as hydrogen evolution, pollution remediation and selective photoreactions. In pursuit of a more efficient photoactive material catalyzing selective photooxidation of an alcohol to an aldehyde, we screened various compositions of PTI and hematite obtained in hydrothermal conditions. Although conversion rates exhibited by the best sample of the composites did not exceed those of pristine PTI, selectivity of the process was improved to 98% at the conversion rate of 99%.
