Gamma ray irradiated AgFeO2 nanoparticles with enhanced gas sensor properties

Boosting and regulating solar energy conversion performance of delafossite AgFeO2 by spin polarization

“…This further implies that 3R-AgFeO 2 and 2H-AgFeO 2 have high purity and crystallinity, guaranteeing that the subsequent property characterization and performance tests are based on single-phase and high-purity samples. Compared with the methods for the preparation of AgFeO 2 reported in the literature, [32][33][34] the combination of the hydrothermal and co-precipitation method in the present work could solve the problems of low purity and mixed crystalline phase.…”

Insight into the Humidity Dependent Pseudo-n-Type Response of p-CuScO2 toward Ammonia

“…Delafossite AgAlO 2 belongs to the group of delafossite p-AMO 2 (A is monovalent Cu or Ag, M is trivalent Al or Ga or Sc, etc. ), which shows promising applications in transparent devices, , photocatalysts for pollutant degradation, , hole transport layers for perovskite solar cells, , photocathodes for water splitting, − dye sensitized solar cells, − and gas sensors. − As a new class of p-type gas sensors, their diverse structural and compositional versatilities provide multiple approaches for performance tailoring. Therefore, we decided to seek material which shows a similar n-type response to ammonia gas at RT but allows a wide range of resistance modulation in the delafossite p-AMO 2 group.…”

Synthesis and characterization of AgFeO2 delafossite with non-stoichiometric silver concentration

“…The co--precipitation method can be used for the preparation of delafossite AgFeO 2 without any special conditions, that is, high temperature or pressure. This method with various modifi cations was employed successfully to prepare silver ferrite, as reported in [2,[23][24][25][26][27][28]. However, most of these methods allowed obtaining the silver ferrite as a mixture of 3R and 2H polytypes in various proportions.…”
