Layer structured Na3Ni2BiO6 with honeycomb ordering is explored as a new high voltage and long life cathode material for sodium-ion batteries.

Indium and nitrogen codoping in ZnO leads to a solid solution of InN in ZnO with a composition of (Zn 1-z In z )(O 1-x N x ). A simple solution combustion method has been adopted to prepare the above materials in less than 10 min with metal nitrates as the metal ion source and urea as fuel. With reference to ZnO, significant increase in lattice parameters was observed with increasing In-content. However, the In 2 O 3 phase was observed along with InN for In content g10%. Optical absorption extended into the visible region, at least up to 550 nm, demonstrates an effective reduction of optical band gap due to the formation of solid solution. A new feature observed just above O 2p valence band in X-ray photoelectron spectroscopy (XPS) suggests the creation of N 2p states from InN; the N 1s core level XPS result too confirms nitride contribution. Raman spectroscopy and secondary ion mass spectrometry results show direct In-N, Zn-N, and In-N-Zn fragments in (Zn 1-z In z )(O 1-x N x ). Catalytic activity explored for oxidation of 2-butanol to ethyl methyl ketone demonstrates a high selectivity at 350 and 400°C. All of the above characteristics suggest the multifunctional nature of (Zn 1-z In z )(O 1-x N x ) and its potential for other applications.
