The design of efficient, durable, and affordable catalysts for oxygen reduction reaction (ORR) evolution (OER) is very indispensable in liquid-type flexible all-solid-state zinc–air batteries. Herein, we present a high-performance bifunctional catalyst with cobalt manganese oxides supported on porous carbon (Co3O4/MnO2/PQ-7). optimized Co3O4/MnO2/PQ-7 exhibited comparable ORR performance commercial Pt/C more superior OER than all the other prepared catalysts, including Pt/C. When applied to...
Abstract Zero or negative emissions of carbon dioxide (CO 2 ) is the need times, as inexorable rising and alarming levels CO in atmosphere lead to global warming severe climate change. The electrochemical reduction (eCO R) value‐added fuels chemicals by using renewable electricity provides a cleaner more sustainable route with economic benefits, which key develop clean economical electrocatalysts. Carbon‐based catalyst materials possess desirable properties such high offset potential for H...
The exploitation of a high-activity and low-cost bifunctional catalyst for oxygen reduction reaction (ORR) evolution (OER) as the cathode is research priority in metal-air batteries. Herein, novel hybrid hortensia-like MnO2 synergized with carbon nanotubes (CNTs) (MnO2/CNTs) controllably synthesized by reasonably designing crystal structure morphology well electronic arrangement.

Rational construction of highly efficient and cheap bifunctional electrocatalysts to boost both oxygen evolution reaction (OER) reduction (ORR) is extremely essential for the wide application rechargeable metal-air battery. In this work, we design a core-shell structural catalyst CoNi dual-metal embedded in nitrogen doped porous carbon (NPC, [email protected]), which developed via pyrolysis CoNi-MOFs, assisting by mesoporous SiO2 effectively inhibit aggregation metal sites. Consequently,...
Abstract In view of global energy transition and environmental issues, electrochemical conversion carbon dioxide (CO 2 ) to high value‐added chemicals by using clean renewable electricity, as an advanced capture, utilization storage (CCUS) technology, demonstrates a promising approach reach the neutrality with additional economic benefits well. Over past decade, various new valid catalysts in CO reduction (ECO2R) have been designed intensively investigated. Unfortunately, constructing...
Regulating the pore structure of a zirfon-based diaphragm is critical to promoting high-rate alkaline electrolyzer, but it still big challenge respond "trade-off" between thickness and current density/gas barrier behavior. In this work, porous hydrophilic skin layer with ∼μm thick polyvinyl alcohol (PVA) has been successfully constructed casted onto thin zirfon-type separator composite (V-Zirfon-350μm). The V-Zirfon-350 μm generates high KOH uptake (>90%), low area resistance (0.2026 Ω cm2)...
α-MnO2 nanotubes-supported Co3O4 (Co3O4/MnO2) and its carbon nanotubes (CNTs)-hybrids (Co3O4/MnO2-CNTs) have been successfully developed through a facile two-pot precipitation reaction hydrothermal process, which exhibit the superior bi-functional catalytic activity for both ORR OER. The high performance is believed to be induced by hybrid effect among MnO2 nanotubes, hollow CNTs, can produce synergetic enhancement. When integrated into practical primary electrochemically rechargeable Zn-air...
As a potential solution to ubiquitous energy concerns, anion-exchange membranes (AEMs) have been widely used as the electrolyte in alkaline fuel cells (AFCs), and significant refinement of AEMs has achieved past few decades. However, it remains unknown whether can be an solid-state supercapacitor or zinc–air battery. A low-cost exchange membrane composed chitosan poly(diallyldimethylammonium chloride) that possesses high OH– conductivity (0.024 S cm–1), strong stability (216 h at 8 M KOH),...
A major challenge in developing zinc-air batteries (ZABs) is to exploit suitable cathodes efficiently accelerate the key electrocatalytic processes involved.

In addition, as-synthesized NiCo2O4@MnO2/carbon nanotube (CNT)-Ni foam can be directly used as an without externally...
The conversion of carbon dioxide (CO2) into high-value added energy fuels and chemicals (CO, formate, C2H4, etc.) through electrochemical reduction (eCO2R) is a promising avenue to sustainable development. However, low selectivity, barren activity poor stability the electrodes hinder large-scale application eCO2R.
