Material Engineering Solutions toward Selective Redox Catalysts for Chemical-Looping-Based Olefin Production Schemes: A Review.

Chemical looping (CL) has emerged as a promising approach in the oxidative dehydrogenation (ODH) of light alkanes, offering an opportunity for significant reductions in emissions and energy consumption in the ethylene and propylene production industry. While high olefin yields are achievable via CL, the material requirements (e.g.

Yolk-shell-type CaO-based sorbents for CO capture: assessing the role of nanostructuring for the stabilization of the cyclic CO uptake.

Improving the cyclic CO uptake stability of CaO-based solid sorbents can provide a means to lower CO capture costs. Here, we develop nanostructured yolk(CaO)-shell(ZrO) sorbents with a high cyclic CO uptake stability which outperform benchmark CaO nanoparticles after 20 cycles (0.17 g g) by more than 250% (0.
