Bifunctional Janus silica spheres for Pickering interfacial tandem catalysis

Nature provides much inspiration for the design of multistep conversion processes, with numerous reactions running simultaneously and without interference in cells, for example. A key challenge in mimicking nature’s strategies is to compartmentalize incompatible reagents and catalysts, for example, for tandem catalysis. Here, we present a new strategy...

Multisize CoS2 particles intercalated/coated‐montmorillonite as efficient sulfur host for high‐performance lithium sulfur batteries

The chemisorption and catalysis of lithium polysulfides (LiPSs) are effective strategies to suppress the shuttle effect in lithium-sulfur (Li-S) batteries. Herein, multisize CoS 2 particles intercalated/coated-montmorillonite (MMT) as an efficient sulfur host is synthesized. As expected, the obtained S/CoS 2 @MMT cathode achieves an absorption-catalysis...

Promoting Electrocatalytic Oxygen Evolution of Ultrasmall NiFe (Hydr)oxide Nanoparticles by Graphene‐Support Effects

Although the activity of electrocatalysts towards oxygen evolution reaction (OER) has achieved considerable improvement by modulating the intrinsic electron structure, the role of supports to OER performance, often being summed to enhancing the conductivity, is not fully explored. In this paper, a proof-of-concept study based on a series of hybrids...
