Abstract Graphene edges exhibit a highly localized density of states that result in increased reactivity compared to its basal plane. However, exploiting this anchor and tune the electronic single atom catalysts (SACs) remains elusive. To investigate this, method Pt SACs with ultra‐low mass loadings at edge‐rich vertically aligned graphene (as low as 0.71 µg cm –2 ) is developed. Angle‐dependent X‐ray absorption spectroscopy density‐functional theory calculations reveal edge‐anchored has...
Single-atom catalysts (SACs) have shown potential for achieving an efficient electrochemical CO2 reduction reaction (CO2RR) despite challenges in their synthesis. Here, Ag2S/Ag nanowires provide initial anchoring sites Cu SACs (Cu/Ag2S/Ag), then Cu/Ag(S) was synthesized by treatment resulting complete sulfur removal, i.e., on a defective Ag surface. The CO2RR Faradaic efficiency (FECO2RR) of reaches 93.0% at partial current density (jCO2RR) 2.9 mA/cm2 under -1.0 V vs RHE, which outperforms...
Abstract The integration of graphene and metal–organic frameworks (MOFs) has numerous implications across various domains, but fabricating such assemblies is often complicated time‐consuming. Herein, a one‐step preparation graphene‐MOF assembly presented by directly impregnating vertical (VG) arrays into the zeolitic imidazolate framework (ZIF) precursors under ambient conditions. This approach can effectively assemble multiple ZIFs, including ZIF‐7, ZIF‐8, ZIF‐67, resulting in their uniform...

Electrochemical generation of hydrogen peroxide (H2 O2 ) is an attractive alternative to the energy-intensive anthraquinone oxidation process. Metal-free carbon-based materials such as graphene show great promise efficient electrocatalysts in alkaline media. In particular, edges possess superior electrochemical properties than basal plane. However, identification and enhancement catalytically active sites at remain challenging. Furthermore, control surface wettability enhance gas diffusion...
Abstract Developing cost‐effective, robust, and durable catalysts for water oxidation in acidic conditions remains a significant challenge the practical application of proton exchange membrane electrolyzers. Cobalt‐based spinel catalysts, known their effective oxygen evolution reaction (OER) activity environments, are promising alternatives to costly iridium‐based catalysts. However, is often limited by poor stability under corrosive oxidative potential. Here it demonstrated that doping Co 2...

Green hydrogen production through the electrocatalytic evolution reaction (HER) is a promising solution for transition from fossil fuels to renewable energy. To enable use of variety electrolytes with different pH values, HER catalysts universality are highly desirable but their performance remains mediocre. Herein, pH‐universal catalyst composed ruthenium nanoparticles decorated on amorphous Ni‐doped MoO 3 ( –Ni–MoO ) nanowire support reported, that is, Ru/ , which achieves enhanced as...
Oxygen reduction reaction through the two-electron pathway holds promise for on-site hydrogen peroxide production; however, achieving high activity without compromising selectivity remains a long-standing challenge in catalyst design. Herein, we overcome this by engineering solid-liquid-gas three-phase interface that creates hydrophobic microenvironment to enhance interfacial mass and electron transfer while retaining active sites. The engineered vertical graphene electrode exhibits greater...

Thus, dynamic Monte Carlo simulations were used to study filler networks formed by one-dimensional on relaxation oriented restrict polymers impose confinement chains inside networks, resulting in higher orientation lower conformational entropy compared those outside chains. confined have stronger crystallizability. During...
