“…Ni doping enhances the conductivity of MnO 2 and increases the surface area and cycle stability of the composite. Microwave irradiation heating reduces energy consumption compared to hydrothermal reactions, effectively shortens the synthesis time of complexes, and improves product homogeneity [ 110 , 111 , 112 ]. For example, Sivaraj et al [ 110 ] reported a microwave-assisted process to synthesize the hybrid CNTs-MnO 2 nanocomposite.…”

Water pollution is one of the most important problems in the field of environmental protection in the whole world, and organic pollution is a critical one for wastewater pollution problems. How to solve the problem effectively has triggered a common concern in the area of environmental protection nowadays. Around this problem, scientists have carried out a lot of research; due to the advantages of high efficiency, a lack of secondary pollution, and low cost, photocatalytic technology has attracted more and more attention. In the past, MnO2 was seldom used in the field of water pollution treatment due to its easy agglomeration and low catalytic activity at low temperatures. With the development of carbon materials, it was found that the composite of carbon materials and MnO2 could overcome the above defects, and the composite had good photocatalytic performance, and the research on the photocatalytic performance of MnO2-carbon materials has gradually become a research hotspot in recent years. This review covers recent progress on MnO2-carbon materials for photocatalytic water treatment. We focus on the preparation methods of MnO2 and different kinds of carbon material composites and the application of composite materials in the removal of phenolic compounds, antibiotics, organic dyes, and heavy metal ions in water. Finally, we present our perspective on the challenges and future research directions of MnO2-carbon materials in the field of environmental applications.

“…This powder was subsequently transferred into a glass vial and subjected to microwave radiation for 45 s at 700 W to yield a fluffy powdery solid of nitrogen-doped carbon nanotubes anchored on reduced graphene oxide (MDNCNT@rGO). Details of electrode preparation and characterization are provided in supplementary file, whereas EMI testing was carried out as per the protocol reported in our previous paper [42].…”

Metal organic framework (MOF)-derived carbon nanostructures (MDC) synthesized by either calcinations or carbonization or pyrolysis are emerging as attractive materials for a wide range of applications like batteries, super-capacitors, sensors, water treatment, etc. But the process of transformation of MOFs into MDCs is time-consuming, with reactions requiring inert atmospheres and reaction time typically running into hours. In this manuscript, we report the transformation of 1,4-diazabicyclo[2.2.2]octane, (DABCO)-based MOFs into iron nitride nanoparticles embedded in nitrogen-doped carbon nanotubes by simple, fast and facile microwave pyrolysis. By using graphene oxide and carbon fiber as microwave susceptible surfaces, three-dimensional nitrogen-doped carbon nanotubes vertically grown on reduced graphene oxide (MDNCNT@rGO) and carbon fibers (MDCNT@CF), respectively, were obtained, whose utility as anode material in sodium-ion batteries (MDNCNT@rGO) and for EMI (electromagnetic interference) shielding material (MDCNT@CF) is reported.

“…15,16 Despite signicant advances in the development of aqueous ZMBs, there are still some obstacles preventing their commercial application. To date, four typical materials have been widely reported for zinc ion storage, Prussian blue analogues, [17][18][19] manganese-based complexes, [20][21][22] V-based complexes, [23][24][25] and organic compounds. 10 Among the widely used inorganic cathodes, vanadium-based materials have attracted conspicuous attention due to their high specic capacity and stable coulombic efficiency.…”
