Mesocrystals (MCs) with high‐index facets may have superior catalytic properties to those with low‐index facets and their nanocrystal counterparts. However, synthesizing such mesocrystal materials is still very challenging because of the metastability of MCs and energetic high‐index crystal facets. This work reports a successful solvothermal method followed by calcination for synthesizing copper oxide‐based...
Metal Ru and vacancy engineering play an important role in oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). However, there are few reports targeted on electrocatalysts by simultaneously employing these two strategies. Herein, theoretical calculation firstly predicts that Ru and VS can regulate the adsorption energy of OER/HER intermediates for NiCo2S4 electrocatalysts. Then,...
Cobalt‐based catalysts are promising alternatives to replace Pt‐ and Cr‐based catalysts for propane dehydrogenation (PDH). However, the sintering and reduction of unstable Co sites cause fast deactivation. Herein, the ultrasmall cobalt oxide clusters encapsulated within silicalite‐1 zeolites (CoO@S‐1) has been obtained via a ligand assistance in situ crystallization method. This CoO@S‐1 catalyst exhibits...
Water splitting to H2 by photocatalysis remains an effective strategy to alleviate the energy crisis. Unfortunately, single‐component photocatalyst still suffers from sluggish reaction kinetics. In this work, a noble‐metal free photocatalytic system of nitrogen‐doped carbon@Co embedded in carbon nanotubes (NC@Co‐NCT)/cadmium sulfide (CdS) is fabricated by coupling CdS nanorods with the metal–organic...
