Surface-Controlled Photocatalysis and Chemical Sensing of TiO<sub>2</sub>, α-Fe<sub>2</sub>O<sub>3</sub>, and Cu<sub>2</sub>O Nanocrystals

A relatively new approach to the design of photocatalytic and gas sensing materials is to use the shape-controlled nanocrystals with well-defined facets exposed to light or gas molecules. An abrupt increase in a number of papers on the synthesis and characterization of metal oxide semiconductors suc...
