Electrocatalytic reduction of nitrate: Fundamentals to ...

Nov 15, 2018· Bismuth exhibits slower nitrate reduction, and exhibits inferior selectivity toward gaseous products (28.2% N 2, 14.5% N 2 O) compared with tin (46.7% N 2, 40.7% N 2 O) . Bismuth has very low toxicity potential in drinking water [ 160, 161 ], but the continuous leaching of bismuth ions occurs during nitrate electrochemical reduction [ 45 ...

The synthesis and thermal redox chemistry of the first antimony (Sb)– and bismuth (Bi)–phosphaketene adducts are described. When diphenylpnictogen chloride [Ph2PnCl (Pn = Sb or Bi)] is reacted with sodium 2-phosphaethynolate [Na[OCP]·(dioxane)x], tetraphenyldipnictogen (Ph2Pn–PnPh2) compounds are produced, and an insoluble precipitate forms from solution. In contrast, when the N ...

Manganese(III) oxide - Wikipedia

Manganese(III) oxide is a chemical compound with the formula Mn 2 O 3. Preparation and chemistry. Heating MnO 2 in air at below 800 °C produces α-Mn 2 O 3 (higher temperatures produce Mn 3 O 4). γ-Mn 2 O 3 can be produced by oxidation followed by dehydration of manganese(II) hydroxide.

"An investigation into the tailoring of bismuth oxide ...

Abstract. Various materials, such as gold and tantalum oxide, have been researched for their use as radiation enhancers or "radiosensitisers" with high Z elements showing a high proficiency. Bismuth oxide nanoceramics have been utilised in many applications but their effectiveness as a high Z radiosensitiser has not yet been examined.

Bismuth Single Atoms Resulting from Transformation of ...

The electrocatalytic reduction reaction of CO2 (CO2RR) is a promising strategy to promote the global carbon balance and combat global climate change. Herein, exclusive Bi-N4 sites on porous carbon networks can be achieved through thermal decomposition of a bismuth-based metal–organic framework (Bi-MOF) and dicyandiamide (DCD) for CO2RR. Interestingly, in situ environmental transmission ...

Mar 01, 2021· Crystallinity is the key for the design of a new generation of carbon‐based catalysts for the oxidative dehydrogenation of ethanol to acetaldehyde. In their Research Article on page 5898, Bastian J. M. Etzold and co‐workers report the synthesis of a novel carbon catalyst that exhibits a comparatively large particle size (100 μm) while featuring an easily accessible crystalline nanostructure.

Liquid Exfoliation of Layered Materials | Science

Jun 21, 2013· ### Background Since at least 400 C.E., when the Mayans first used layered clays to make dyes, people have been harnessing the properties of layered materials. This gradually developed into scientific research, leading to the elucidation of the laminar structure of layered materials, detailed understanding of their properties, and eventually experiments to exfoliate or delaminate them into ...
