Abstract Nanostructured metal-nitrides have attracted tremendous interest as a new generation of catalysts for electroreduction CO 2 , but these structures limited activity and stability in the reduction condition. Herein, we report method fabricating FeN/Fe 3 N nanoparticles with interface exposed on NP surface efficient electrochemical reaction (CO RR). The is populated Fe−N 4 coordination sites respectively that show desired catalysis synergy to enhance CO. Faraday efficiency reaches 98%...
Copper oxide (Cu2O) is considered a promising catalyst that can effectively reduce the overpotential of CO2 reduction reaction (CO2 RR) and increase selectivity for C2+ products. However, developing high-performance stable CO2-to-ethanol (C2H5OH) based-Cu2O electrocatalysts remains challenging. In this work, Cu2O@Cu2S twin heterojunction catalysts with multitwin boundaries are designed to afford C2H5OH productivity at low potential through electrocatalytic RR, highly dependent on facet...
2D/2D nitrogen-vacancy-rich Ti 3 C 2 T x /g-C N 4 (TC/CN) Schottky heterojunctions with interfacial N–Ti bonds have been successfully constructed as an efficient photocatalyst for simultaneous H evolution coupled selective aromatic alcohol oxidation.
Effective separation of photogenerated charge carriers, enhanced reduction ability conduction band electrons, and improved light harvesting are crucial for the significant improvement photocatalytic H 2 evolution activity over Z-scheme ZnIn S 4 /v-Nb O 5 heterojunction.
Z-scheme heterostructure-based photocatalysts consist of a reduction photocatalyst and an oxidation photocatalyst, enabling them to possess high capacity for both oxidation. However, the coupling reaction between photocatalytic H2 generation through water sterilization using systems has been rarely reported. Herein, 1D W18O49 nanowires embedded over 2D g-C3N4 nanosheets are well-constructed as integrated heterojunction. Experimental results density functional theory calculations not only...
