Minimizing food wastes and finding a second life use for industrial residuals have become some of the top priorities modern society. This work considers spent eggs mussels shells, as well marble dust, raw sources to develop nanoparticles involving renewable resources in both their preparation adoption technological applications. Specifically, Ca/Mg-based were obtained by evaporating such physic...

Reverse water–gas shift reaction using renewable H2 is a promising route for CO2 upgrade, however, it restricted by the equilibrium. The chemical looping reverse oxygen carriers (i.e. Fe) has proven more effective utilization process to produce CO. However, with high purity needed obtain concentrated Herein, we propose calcium dual one-pot sol–gel synthesized Ca-Fe functional materials (DFMs). ...
