Electrochemical reduction of CO2 to high-value hydrocarbons and oxygenates is an attractive technique store intermittent renewable energy. Diverse catalysts are capable catalyzing the CO conversion, while further occurs almost exclusively on Cu. Monocomponent Cu suffer from high overpotential low Faradaic efficiency oxygenates. Combining conversion Au, Ag, single-atom catalysts, etc., with a promising strategy achieve selectivity formation rate highly reduced products. Numerous tandem have...
Electrochemical CO2 reduction in acidic electrolytes is a promising strategy to achieve high utilization efficiency of CO2. Although alkali cations play vital role suppressing hydrogen evolution and promoting reduction, they also cause precipitation bicarbonate on the gas diffusion electrode (GDE), flooding electrolyte through GDE, drift pH. In this work, we realize electroreduction metal cation-free by covering catalyst with cross-linked poly-diallyldimethylammonium chloride. This...
Conducting electrochemical reduction of CO2 in acidic media can effectively increase the utilization efficiency CO2. Alkali cations (M+) are indispensable for media, while high concentration M+ results bicarbonate precipitation a gas diffusion electrode. To develop selective and sustainable techniques quantitative understandings cation effects on rates H+ demanded. Previous study shows that modulate electric field distribution double layer, which suppresses migration stabilizes intermediate...
Developing high-performance and low-cost electrocatalysts for oxygen reduction reaction (ORR) is still a great challenge Al-air batteries. Herein, CeO2, unique ORR promoter, was incorporated into ketjenblack (KB) supported Co3O4 catalyst. We developed facile two-step hydrothermal approach to fabricate Co3O4-CeO2/KB as catalyst The activity of Co3O4/KB significantly increased by mixing with CeO2 nanoparticles. In addition, the showed better electrocatalytic performance stability than 20 wt %...
Scalable, low-cost and highly efficient catalysis of oxygen electrocatalytic reactions (ORR/OER) are required for the rapid development clean renewable energy conversion/storage technologies. Herein, two types α-MnO2 nanorods were prepared under hydrothermal treatment at 150 °C 0.5 h (MnO2-150-0.5) or 120 12 (MnO2-120-12), then supported on N-doped ketjenblack carbon (N-KB) as bi-functional ORR/OER catalysts. Their activities toward ORR OER investigated systematically. As a result,...
To cater for the development of clean hydrogen energy, an efficient oxygen evolution reaction catalyst is urgently needed to increase efficiency water splitting. A novel three-dimensional (3D) ternary transition metal hydroxide, FeCoNi-layered double hydroxide (FeCoNi-LDH) nanocage has been successfully synthesized by cation exchange using metal–organic framework as a template. The obtained FeCoNi-LDH displays excellent electrocatalytic activity, such low overpotential 299 mV at j = 10 mA...
Metal–nitrogen–carbon single-atom catalysts with metal sites at the edge of carbon layers are widely used in electrocatalytic processes such as CO2 reduction. For prepared pyrolysis methods, local structure sites, including type ligands and coordination number, cannot be precisely controlled, making it difficult to investigate relationship between properties structure. In this work, Co–Nx complexes 2–4 pyridinic anchored black conjugated pyrazine linkers model edge-site Co catalysts. Only...
Traditional noble metal platinum (Pt) is regarded as a bifunctional oxygen catalyst due to its highly catalytic efficiency, but commercial availability and application often restricted by high cost. Herein, cheap effective mixed with α-MnO2 nitrogen-doped Ketjenblack (N-KB) (denoted MnO2-SM150-0.5) examined potential electrocatalyst in reduction reactions (ORR) evolution (OER). This prepared redox reaction between K2S2O8 MnSO4 acid conditions facile hydrothermal process (named the SM...
In recent years, transition-metal phosphides (TMPs) have drawn increasing attention as a battery-type cathode material for battery–supercapacitor hybrid (BSH) devices owing to their superior electrochemical activity well rich valence state, and the reasonably designed composition structure of bimetallic are considered be an efficient approach fully utilize advantages overcome defects low rate capability poor cycle life potential applications. Herein, metal-rich porous Cu–Co–P well-defined...
MIL-88B(Cr) is a prototypical flexible chromium-based metal-organic framework (MOF), which possesses extremely strong water/thermal stability and excellent “swelling/breathing” ability. However, in previous studies, there have been very few reports on due to unclear synthesis details. Here, we found that the pure can be facile synthesized through hydrothermal method with co-use of nitric acid acetic (molar ratio = 1:15). The obtained was sufficiently characterized by diverse techniques...
