Carbon-supported MnO2 nanoflowers: Introducing oxygen vacancies for optimized volcano-type electrocatalytic activities towards H2O2 generation

Construction of Defect‐Rich Ni‐Fe‐Doped K0.23MnO2 Cubic Nanoflowers via Etching Prussian Blue Analogue for Efficient Overall Water Splitting

“…For instance, highly active Mn oxide‐based electrocatalysts constituted by ultrathin nanosheets or nanoflowers, with abundant exposed surfaces, have been fabricated 18. Introducing many oxygen vacancies and Mn 3+ ions into Mn oxides is also a good method to promote catalytic activity 19. Therefore, elaborate structural design and defect engineering are possible approaches to obtain Mn oxide‐based materials with reinforced catalytic activity toward efficient and low‐cost overall water splitting.…”

Efficient H2O2 electrogeneration at graphite felt modified via electrode polarity reversal: Utilization for organic pollutants degradation

“…Generally, the methods are divided into two types. The first is depositing other catalysts on the surface of carbonaceous materials, such as graphene [21], carbon nanotubes [22] [23], acetylene black [24], carbon black [9], and metal oxides (i.e., MnO 2 [25], CeO 2 [26]). The second is heteroatom-doping, such as O [27] [28], N [29] [30], and F [31].…”

Structure and Electrochemical Properties of Mn3O4 Nanocrystal-Coated Porous Carbon Microfiber Derived from Cotton

“…The BET specific surface area of the Mn 3 O 4 /PCM was determined to be 51.9 m 2 ·g −1 , which was much larger than that of pristine Mn 3 O 4 (10.8 m 2 ·g −1 ). The higher surface area and pore volume is beneficial to the contact of the electrolytes with the active materials, and can further increase the electrochemical properties [ 6 , 8 , 10 ]. The TG-DTA curves of the hydrothermal product are shown in Figure 2 d. Two endothermic peaks were observed in the range of 100‒200 °C because of the adsorbed water.…”

“…To address these issues, scholars have proposed the fabrication of many MnO x /carbon composites in recent years [ 8 , 9 ]. Among the carbon materials, using low-cost natural resources, biowaste, and food waste are highly effective ways to achieve the large-scale production of electrode materials [ 10 , 11 , 12 ].…”
