Facile metal-free reduction-based synthesis of pristine and cation-doped conductive mayenite.

ABSTRACT: In the present study we synthesized conductive nanoscale [Ca₂₄Al₂₈O₆₄]⁴⁺(4e^-) (hereafter denoted as C₁₂A₇:e^-) material, and reduced graphene oxide (rGO) was produced, which was unexpected; graphene oxide was removed after melting the sample. The conductivity of C₁₂A₇:e^- composites synthesized at 1550 °C was 1.25 S cm^-1, and the electron concentration was 5.5 × 10¹⁹ cm^-3. The estimated BET specific surface area of the highly conductive sample was 20 m² g^-1. Pristine C₁₂A₇:e^- electride was obtained by melting the composite powder, but the nano size of C₁₂A₇:e^-
