Nanostructuring Copper Tungstate Photoanodes: Performance Enhancement and Fundamental Limitations

Small Structures, Volume 7, Issue 3, March 2026.
Nanostructuring of CuWO4 photoanodes yields a ~ tenfold photocurrent enhancement compared to dense films, reaching 0.6 mA cm−2 at 1.23 V versus reversible hydrogen electrode, among the best values reported for this material. Yet, performance remains far below the theoretical limit due to severe bulk recombination and poor electron transport ...

Spark plasma sintering‐assisted sol‐gel Pechini method: An efficient approach for bulk InGaO3(ZnO)m synthesis and texturation

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This article reports on the development of a spark plasma sintering (SPS)‐assisted sol‐gel method for the synthesis of dense pellets, belonging to the series of InGaO3(ZnO)m homologous phases, where m is an integer. We show that using this synthesis route, the sintering temperature is significantly decreased down to 950–1000°C as compared to ...

Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.
