Synthesis of high-quality Ni2P hollow sphere via a template-free surfactant-assisted solvothermal route

Solvothermal synthesis and gas-sensing performance of Co3O4 hollow nanospheres

“…Although Co 3 O 4 nanostructures with various morphologies have been synthesized [23][24][25][26][27], very little work has been directed towards fabricating gas sensors based on these nanostructures, and there are no reports on the gas-sensing properties of Co 3 O 4 hollow nanospheres. It is well known that the surfactant-assisted solvothermal route is very effective to synthesize various nanostructured materials [28][29][30]. Herein, we report the solvothermal synthesis of p-type Co 3 O 4 hollow spheres and their gas-sensing properties towards the vapors of a variety of typical organic solvents and fuels, including acetone, ethanol, toluene, butanol, propanol, and gasoline.…”

One-step template-free synthesis of hollow core–shell α-Fe2O3 microspheres with improved lithium storage and gas-sensing properties

“…Therefore, the dissolution primarily occurred via an Ostwald ripening process in the spheres' interior not in the exterior, and eventually hollow core-shell spheres are yielded. 30,31 During the long-drawn hydrothermal process, the presence of relatively abundant H + shifts the equation toward the right-hand side and enhances the degree of dissolution (eqn (3)), which resulted in the evacuation of some holes on the cores. Finally, hollow core-shell α-Fe 2 O 3 microspheres were obtained.…”

Hydrothermal synthesis method of nickel phosphide nanoparticles

“…The probable reaction process for the formation of Ni 2 P/ Ni 12 P 5 could be summarized as follows (Wang et al 2008). …”
