Cerium(IV) oxide used as a mixed conductor. Ceria is of interest as a material for solid oxide fuel cells (SOFCs) because of its relatively high oxygen ion conductivity (i.e. oxygen atoms readily move through it) at intermediate temperatures (500–650 °C) and lower association enthalpy compared to Zirconia system. The cerium(IV) oxide–cerium(III) oxide cycle or CeO/CeO cycle is a two step thermochemical water splitting process based on cerium(IV) oxide and cerium(III) oxide for hydrogen production. Cerium(IV) oxide Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a
Graphite oxide deposition is done under ambient conditions and can use a wide range of substrates. Langmuir-Blodgett has been suggested to produce films with better quality compared to other methods such as chemical vapor deposition, spin coating or dip coating. Graphene oxide can be further reduced into graphene. Nonlinear optical materials are of great importance for ultrafast photonics and optoelectronics. Recently, the giant optical nonlinearities of graphene oxide (GO) has been proved useful for a number of applications. For example, the optical limiting of GO are indispensable to protect sensitive instruments from laser-induced damage. And the saturable absorption can be used for
