Direct growth of defect-rich MoO3−xultrathin nanobelts for efficiently catalyzed conversion of isopropyl alcohol to propylene under visible light

We report a robust and highly active photocatalyst for the C3H6 evolution reaction that is constructed by surfactant-free growth of oxygen vacancy-rich MoO3−x ultrathin nanobelts. Under visible-light irradiation, the new catalyst can selectively (95% selectivity) dehydrate isopropyl alcohol into C3H6 with yields above 98%.
