New opportunities for tailored nanoparticle catalysts through exsolution from inherently disordered defect fluorite-type oxides

Exsolution of Ru nanoparticles from defective fluorite-type Y 2 Zr 2− x Ru x O 7 exhibits exceptional tunability and produces a promising catalyst for the rWGS reaction, achieving near-equilibrium CO 2 conversion and 100% selectivity to CO above 650 °C.
