Activity and selectivity regulation through varying the size of cobalt active sites in photocatalytic CO₂ reduction

Abstract

The development of efficient and economical catalysts for photocatalytic reduction of CO2 into chemical feedstocks is highly desirable for addressing both the global energy crisis and carbon emission problem.

Highly Efficient Photoreduction of Low‐Concentration CO2to Syngas by Using a Polyoxometalates/RuIIComposite

“…[16] Ru II complexes (e.g.,e specially [Ru(bpy) 3 ]Cl 2 ,b py = bipyridine) with accessible redox states, high quantum efficiency, and long-lived excited states, are some of the most widely used metal complexes in CO 2 photoreduction. [17][18][19][20][21] The combination of thesec omplexes and semiconductors is considered as an efficient way to enhance photocatalytic reactivity and stabilityu nder visible-light irradiation. [22,23] Also, the heterogeneous process will facilitate catalystr e-use and liquid product separation.…”

Carbon Nanomaterials From Metal-Organic Frameworks: A New Material Horizon for CO2 Reduction

“…The Zn and reduced Co presented in the carbon matrix could prevent Co active sites from aggregation. They came up with the idea that the size of Co active sites could be regulated by adjusting the Zn/Co ratio, thus influencing the compositions of the resulting products (Mu et al, 2018 ).…”

Controlled synthesis of Bi- and tri-nuclear Cu-oxo nanoclusters on metal–organic frameworks and the structure–reactivity correlations

“…Some reaction mechanisms are governed by the adsorption configurations of the substrates. 18,19 We, however, still cannot accurately predict the effect of these parameters on catalysis, which greatly hinders the precise engineering of this class of highly potent and atom-economical catalysts.…”
