The utility of carbonaceous materials for hybrid semiconductor photocatalysts has been rapidly increasing in recent years due to the synergetic effect via interfacial charge transfer reactions. In this study, we prepared a novel graphdiyne–ZnO nanohybrid by hydrothermal method and examined its photocatalytic properties on degradation two azo dyes (methylene blue rhodamine B). Interestingly, nanohybrids showed superior than that bare ZnO nanoparticles as evidenced absorption spectra total...
Hydrogen spillover (HSo) has emerged to upgrade the hydrogen evolution reaction (HER) activity of Pt-support electrocatalysts, but it is not applicable deprotonated oxygen (OER). Non-precious catalysts that can perform well in both HSo and deprotonation (DeP) are extremely desirable for a sustainable economy. Herein, an affordable MoS2 /NiPS3 vertical heterostructure catalyst presented synergize DeP efficient water electrolysis. The internal polarization field (IPF) clarified as driving...
Abstract Rationalizing non‐precious pH‐robust electrocatalysts is a crucial priority and required for multi‐scenario hydrogen production customization. Herein, an amorphous–crystalline CoBO x /NiSe heterostructure theoretically profiled constructed efficient water electrolysis. The crystalline lattice confinement induces CoCo bond shortening B‐site delocalization on amorphous , resulting in decreased d‐p band center difference (Δε ) toward the balanced intermediates adsorption/desorption....
Abstract Metal–support interaction (MSI) is witnessed as an essential manner to stabilize active metals and tune catalytic activity for heterogonous water splitting. Kinetically driving the electrolysis (WE) appeals a rational MSI system with coupled electron‐donating/accepting (e‐D/A) characters hydrogen/oxygen evolution reactions (HER/OER). However, metal stabilization effect by will in turn restrict deblocking of e‐D/A properties challenge full electrocatalytic optimization. This study...
Abstract The effectuation of pH‐universal electrocatalysis is highly attractive but still challenging for the hydrogen evolution reaction (HER). It appeals not only facilitated electron transport also kinetical proton mass transfer. In this study, a via‐hole Ru/MoO 2 confined heterostructure profiled as metal‐support platform electron/mass transfer‐boosted HER studies. indicated that as‐formed Ru─O─Mo bridge can modulate electronic at interface, and adsorption transfer are kinetically...
Abstract Metal-support electronic interactions play crucial roles in triggering the hydrogen spillover (HSo) to boost evolution reaction (HER). It requires supported metal of electron-rich state facilitate proton adsorption/spillover. However, this contradicts traditional metal→support electron transfer protocol and is not compatible with electron-donating oxygen (OER), especially proton-poor alkaline conditions. Here we profile an Ir/NiPS 3 support structure study Ir states performances...
The emerging lattice-oxygen oxidation mechanism (LOM) presents attractive opportunities for breaking the scaling relationship to boost oxygen evolution reaction (OER) with direct OLattice-*O interaction. However, currently LOM-triggering rationales are still debated, and a streamlined physicochemical paradigm is extremely desirable design of LOM-defined OER catalysts. Herein, Ni metal-organic framework/black phosphorene (NiMOF/BP) heterostructure theoretically profiled constructed as...
Abstract Surface reconstruction (SRC) is a common phenomenon and promotion manner for Ni/Co‐based precatalysts during the water splitting process. However, catalytic surface will in turn complicate streamlined prediction modeling on activity. Hence, rational design of anti‐SRC catalysts highly desirable, but challengeable. In this article, series affordable bimetal‐incorporated black phosphorene (BP) are constructed by an situ electro‐exfoliation/insertion method electrolysis. It found that...
