A Simple Descriptor toward Optimizing Electrocatalytic N Oxidation to HNO Performance over Graphene-Based Single-Atom Catalysts.

Single-atom catalysts (SACs) exhibit tremendous advantages in the electrochemical N oxidation reaction (ENOR) to HNO, which is an eco-friendly alternative to the synthesis of conventional industrial nitric acid and nitrates, but methods to rationally design and rapidly screen high-efficiency ENOR SACs are unclear. Herein, taking pyridinic nitrogen-doped graphene-supported SACs as an example, a simple descriptor has been proposed to evaluate the ENOR performance through systematically constructing a surface reaction phase diagram. This descriptor is comprised of merely the geometric information and inherent atomic properties (occupied d electron number, electronegativity, and coordinate number) that can accurately predict the activity and selectivity of ENOR, independent of DFT simulations.

Engineering a Zn-NC electron bridge boosting charge transfer in ZnO/CN Z-scheme heterojunction for efficient photocatalytic disinfection.

Although photocatalytic disinfection can avoid secondary pollution and other shortcomings compared to traditional disinfection methods, its development is seriously hindered by poor charge separation and transfer efficiency. Herein, we design a Zn-NC (single Zn atoms embedded in nitrogen-doped carbon) bridged ZnO/CN Z-scheme heterojunction (ZnO/Zn-NC/CN) with robust interface contact by a multi-interfacial engineering strategy to achieve highly efficient separation and transfer of charge. Experimental and theoretical analyses demonstrate that the tightly integrated interface and excellent electrical conductivity of Zn-NC electron bridges ensure effective transfer of photogenerated charge carriers.

Tailoring hypervalent Nickel induced by oxygen vacancy toward enhanced oxygen evolution reaction performance in self-supporting NiFe-(oxy)hydroxides electrodes.

NiFe-(oxy)hydroxides are the most active transition metal oxide electrocatalysts for oxygen evolution reaction (OER) under the alkaline media. Herein, we controllably manipulated oxygen vacancy (V)-tunable NiFe-(oxy) hydroxides that their OER performances possessed a volcano-type relationship with V concentration, positively-correlated with Ni/Ni ratio. Theoretical simulations further unearthed the enhanced activation and dissociation of HO by the inserting of V.

In situ synthesis of graphitic carbon nitride nanosheet/TiCT MXene/TiO Z-scheme heterojunctions boosting charge transfer for full-spectrum driven photocatalytic sterilization.

The development of a full-spectrum responsive photocatalytic germicide with excellent charge separation efficiency to harvest high antimicrobial efficacy is a key goal yet a challenging conundrum. Herein, graphitic carbon nitride nanosheet (PCNS)/TiCT MXene/TiO (PMT) Z-scheme heterojunctions with robust interface contact were crafted by in situ interfacial engineering. The strong internal electrical field (IEF) from PCNS to TiO, evinced by the Kelvin Probe Force Microscopy (KPFM) characterization, can obtain high charge separation efficiency with 73.

Rational Construction of a Triple-Phase Reaction Zone Using CuO-Based Heterostructure Nanoarrays for Enhanced Water Oxidation Reaction.

The development of high-efficiency oxygen evolution reaction (OER) electrocatalysts for the production and conversion of clean energy is paramount yet also full of challenges. Herein, we proposed a simple and universal method to precisely fabricate the hierarchically structured CuO/TMOs loaded on Cu foil (CuO/TMOs/CF) (TMO represents MnO, NiO, CoO, and CuO) nanorod-array electrodes as a highly active and stable OER electrocatalyst, employing Cu(OH)/CF as a self-sacrificing template by the subsequent HO-induced chemical deposition (HiCD) and pyrolysis process. Taking CuO/MnO/CF as an example, we systematically investigated its structure-performance relationship via experimental and theoretical explorations.

Fabrication of a 2D/2D MXene/CN Heterojunction for Photothermally Assisted Photocatalytic Sterilization under Visible Light Irradiation.

Constructing an efficient visible light-responsive antibacterial material for water treatment remains a principal goal yet is a huge challenge. Herein, a 2D/2D heterojunction composite with robust interfacial contact, named MXene/CN (MCN), was controllably fabricated by using a urea molecule intercalated into MXene following an calcination method, which can realize the rapid separation and migration of photogenerated carriers under visible light irradiation and significantly improve the carrier concentration of the MXene surface, thus generating more reactive oxygen species. The generation of heat induced by MXene could also increase photogenic electron activity to facilitate the photocatalytic reaction using time-resolved photoluminescence characterization.
