The question of whether the metal chalcogenides (phosphides) that have been acknowledged to be efficient materials for bifunctional electrocatalysts really perform as active species or just "pre-catalysts" has debated. Herein, a series operando measurements, including in situ X-ray absorption spectroscopy, liquid-phase transmission electron microscopy, and Raman were conducted unravel real time structural chemical stability P-substituted CoSe2 under both hydrogen oxygen evolution reactions...
It has been widely acknowledged that most electrocatalysts would undergo a structural reconstruction during the water splitting as well carbon dioxide (CO2) reduction reactions. Recently developed in situ and/or operando methods are gaining increasing interest judicious tools for investigations of heterogeneous electrocatalysis. In this Perspective, recent applications various characterization techniques tracking catalysts, identifying real active sites, and recording intermediates formed...
Abstract Rationally designing active and durable catalysts for the oxygen evolution reaction (OER) is of primary importance in water splitting. Perovskite oxides (ABO 3 ) with versatile structures multiple physicochemical properties have triggered considerable interest OER. The leaching A site cations can create nanostructures amorphous motifs on perovskite matrix, thus facilitating OER process. However, selectively dissolving simultaneously obtaining more derived from B remains a great...
Developing highly efficient and affordable noble-metal-free catalysts toward the hydrogen evolution reaction (HER) is an important step economical production of hydrogen. As a nonprecious-metal catalyst for HER, molybdenum nitride (MoN) has excellent corrosion resistance high electrical conductivity, but its catalytic activity still inadequate. Here we report our findings in dramatically enhancing HER MoN by creating porous MoN@nitrogen-doped carbon (MoN-NC) nano-octahedrons derived from...
Understanding the dynamic structural reconstruction/transformation of catalysts during electrochemical CO2 reduction reaction (CO2RR) is highly desired for developing more efficient and selective catalysts, yet still lacks in-depth realization. Herein, we study a model system copper nanowires with various degrees silver modifications as electrocatalysts CO2RR. Among them, Cu68Ag32 nanowire catalyst achieves highest activity selectivity toward methane an extremely high faradaic efficiency...

Perovskite oxides exhibit potential for use as electrocatalysts in the oxygen evolution reaction (OER). However, their low specific surface area is main obstacle to realizing a high mass-specific activity that required be competitive against state-of-the-art precious metal-based catalysts. We report enhanced performance of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) OER with intrinsic significantly higher than benchmark IrO2, and this result was achieved via fabrication an amorphous BSCF nanofilm on...
Abstract Electrochemical conversion of CO 2 into ethane is seldom observed because the generally higher selectivity towards methane, ethylene, and ethanol. Consequently, little experimental evidence for its reaction mechanism exists thus remains largely unknown. Now, by combining electrochemistry with in situ X‐ray absorption fine‐structure Raman techniques, iodide‐derived copper (ID‐Cu) oxide‐derived (OD‐Cu) systems were studied to obtain a deeper understanding mechanism. With trace iodine...
Guaranteeing satisfactory catalytic behavior while ensuring high metal utilization has become the problem that needs to be addressed when designing noble-metal-based catalysts for electrochemical reactions. Here, well-dispersed ruthenium (Ru) based clusters with adjacent Ru single atoms (SAs) on layered sodium cobalt oxide (Ru/NC) are demonstrated as a superb electrocatalyst alkaline HER. The Ru/NC catalyst demonstrates an activity increase by factor of two relative commercial Pt/C. Operando...

We use KOH-activated persulfate convert fulvic-like acid and humic-like acid. mix the product with attapulgite obtain a slow-release nano fertilizer. apply this nano-fertilizer chickweeds growing pots, resulting improved yield root elongation. These results indicate that could be recycled purposes,...
Practical application of hydrogen production from water splitting relies strongly on the development low-cost and high-performance electrocatalysts for evolution reaction (HER). The previous researches mainly focused transition metal nitrides as HER catalysts due to their electrical conductivity corrosion stability under acidic electrolyte, while tungsten have reported poorer activity HER. Here nitride is optimized through rational design a nitride-carbon composite. More specifically, (WN

Surface reconstruction during electrocatalysis can form fresh‐composition electrocatalysts unusual amorphous phases in situ, which are more active but difficult to prepare by conventional methods. Here, a facile strategy based on fast nanofilm precursors proposed exploring precious‐metal‐free catalysts good...
