Developing a cost-effective and highly efficient electrocatalyst with superior catalytic activity is crucial for clean green water splitting, including the hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR). The single-atom catalyst (SAC) breakthrough in industrial catalysis because of advantages maximum metal atom utilization, single active sites, strong metal–support interactions, great potential to accomplish high performance selectivity. Herein, we investigate...
In line with current research goals involving water splitting for hydrogen production, this work aims to develop a noble-metal-free electrocatalyst superior evolution reaction (HER). A single-step interfacial activation of Ti3C2Tx MXene layers was employed by uniformly growing embedded WS2 two-dimensional (2D) nanopetal-like sheets through facile solvothermal method. We exploited the interactions between nanopetals and nanolayers enhance HER performance. much safer method adopted synthesize...
Catalytic mechanisms and bonding analysis of NO oxidation reduction on Cr single-atom catalysts (SAC) dispersed the graphyne (GY) surface have been systematically investigated using first-principles theoretical methods. GY is a decent support for isolated transition-metal (TM) atom because most active sp-hybridized carbon atoms exist surface. All single TM are trapped into void existed in form. The molecular geometries adsorbate binding energies NO@TM–GY, ON@TM–GY, O2@TM–GY configurations...
Abstract We report the very first example of a catalyst based on ternary composite graphitic carbonitride (g‐C 3 N 4 ), ceria (CeO 2 ) and magnetite (Fe O for overall water splitting in 1.0 M KOH. Synergy between components due to electronic effects results highly efficient which catalyzes Oxygen Evolution Reaction (OER) Hydrogen (HER) at substantially low overpotentials (400 mV 310 respectively) produce benchmark current density (10 mA cm −2 ). OER activity catalysts surpasses that RuO...
Single‐atom catalysts (SACs) have received significant interest for optimizing metal atom utilization and superior catalytic performance in hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR). In this study, we investigate a range of single‐transition (STM 1 = Sc , Ti V Cr Mn Fe Co Ni Cu Zr Nb Mo Ru Rh Pd Ag W Re Os Ir Pt Au ) atoms supported on graphyne (GY) surface HER/OER ORR using first‐principle calculations. Ab initio molecular dynamics (AIMD) simulations phonon dispersion...
In practical applications such as oxygen evolution reaction (OER), reduction (ORR), and hydrogen (HER), an electrocatalyst that is highly active stable essential.
The proposed new non-noble-metal Mo 1 /PMASAC is potentially more efficient and selective than the current best Mo/BN FeN 3 /embedded graphene SAC, preferred mechanism an enzymatic pathway.
Visible light active g-C3N4(0.94)/CeO2(0.05)/Fe3O4(0.01) ternary composite nanosheets were fabricated by facile co-precipitation routes. The density functional theory (DFT) computations investigated changes in geometry and electronic character of g-C3N4 with CeO2 Fe3O4 addition. Chemical surface characterizations explored XRD, XPS, SEM, TEM, PL, DRS Raman measurements. PL spectroscopy evidenced the energy band gap tailoring from 2.68 eV for bulk 2.92 to 2.45 nanocomposite. Efficient...
Abstract The surface structure and lattice strain necessary to optimize oxygen reduction reaction (ORR) in a cost‐effective electrocatalyst still requires systematic exploration. Here, by means of oxidative etching confinement stacking faults, comparative study the influence defects on growth PtAgPb core‐shell nanoplates for ORR is conducted. Stacking faults are key forming core–shell induce tensile compressive strains improve catalytic performance nanoplates. In particular, arising from...
Abstract Tuning the crystal phase of alloy nanocrystals (NCs) offers an alternative way to improve their electrocatalytic performance, but, how heterometals diffuse and form ordered‐phase remains unclear. Herein, for first time, mechanism forming tetrametallic nanoplates (NPLs) is unraveled. The observations reveal that intermetallic nucleates through crystallinity alteration seeds then propagates by reentrant grooves. Notably, grooves act as intermediate NCs ordered‐phase, eventually...
