Chemistry – A European Journal, EarlyView.One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Defect chemistry and transport properties of BaxCe0.85M0.15O3-d [PDF]
, 2004 The site-incorporation mechanism of M3+ dopants into A2+B4+O3 perovskites controls the overall defect chemistry and thus their transport properties. For charge-balance reasons, incorporation onto the A2+-site would require the creation of negatively ...

EcoEnergy, EarlyView.Subnanoscale CeO2‐Cu2O particles can efficiently catalyze the hydrogenation of the key intermediate *CO to CH4 at an impressive rate of 2818 μmol g−1 h−1 in photothermal CO2 reduction. ABSTRACT Water‐mediated photothermal CO2 reduction to CH4 is promising for renewable energy storage and carbon neutrality, but its selectivity and efficiency are limited
