“…The most widely used method to synthesize this material consists of the solid-state reaction between copper and iron oxides at temperatures above 800 ºC under an inert atmosphere [158][159][160]. However, recently there are many promising reports that synthesis delafossite at normal temperature from 100-180 ºC [161][162]. The synthesis of target material is dependent on the reaction temperature.…”

Recently, numerous delafossite oxides in nanoscale have been reported for diverse applications. The present review summarized the recent overall views of delafossite nanoparticles in diverse applications such as energy, catalysis, photocatalysis, nanomedicine, sensors, electrochemical devices and environmental concerns. Delafossite nanoparticles possess unique features such as different and wide chemical composition, large surface area, small energy gap, ability for further functionalization, possess dual-active sites with different oxidation states (A+and M3+), and eager for doping with various species with feasibility to undergo structure modification. Thus, they provided promising application such as solar cell, photocatalysis, hydrogen production, bioactive materials, separation purposes and others. Pros, cons, current and future status were also reviewed.

“…1 The development of the p-type TCOs is due to their applications, in combination with n-type TCOs, in transparent p-n junctions, [2][3][4][5] which effectively enhance the efficiency of many high-technology optoelectronic devices. [6][7][8] The p-type characteristics of CuAlO 2 have been theoretically [9][10][11][12] and experimentally 4,13,14 investigated to understand its conduction mechanism, including hybridized antibonding, 15 charge transport, 4 the defect mechanisms, 10,13,16 etc.…”

The effects of X-doping (X = S, Se, Te and Po) on the structural, electronic and optical properties of hexagonal CuAlO2 were studied using first-principles density functional theory. The calculated results showed the obtained lattice constants to increase with increasing atomic number, and the X-doping to be energetically more favorable under Al-rich conditions. The calculated electronic properties showed decreased bandgaps with increasing atomic number, which was due to the better covalent hybridizations after sulfuration doping. The enhanced covalency was further confirmed by calculating the Mulliken atomic populations and bond populations. The density of states indicated the increase of the contribution to antibonding from the X-p states to be a benefit for p-type conductivity. Moreover, the X-doping induced a red shift of the absorption edge.
