摘要

Hollow In_2O_3 spheres were prepared via a P123-assisted one-step solvothermal process for the first time. Ethanol medium played a key role in the direct cubic In_2O_3 phase formation whereas the triblock copoly-mer acted as a structure directing agent in the formation of the hollow spheres. The gas sensing properties of the as-prepared In_2O_3 hollow spheres were investigated. Compared to the products synthesized without P123, the In_2O_3 hollow spheres exhibited much faster response and higher sensitivity toward HCHO vapor.
