Summary
An external magnetic field accelerates electrocatalytic oxidation of biomass-derived 2,5-bis(hydroxymethyl)furan (BHMF) to 2,5-furandicarboxylic acid (FDCA). This magnetic field enhances BHMF diffusion and reaction kinetics, significantly improving yield and reducing reaction time.

- Catalysis
- Electrochemistry
- Materials Science
Background:
- External fields are crucial for tuning catalyst performance.
- Electrocatalytic oxidation of biomass-derived molecules is vital for sustainable chemistry.
Purpose of the Study:
- To investigate the effect of an external magnetic field on the electrocatalytic oxidation of 2,5-bis(hydroxymethyl)furan (BHMF).
- To enhance the conversion efficiency and yield of 2,5-furandicarboxylic acid (FDCA) production.
Main Methods:
- Fabrication of an ox-NiCoP electrocatalyst.
- Electrocatalytic oxidation of BHMF under an external magnetic field (0.48 T).
- Kinetic analysis to determine reaction rate constants and charge transfer resistance.
Main Results:
- A 0.48 T magnetic field increased BHMF conversion by 27.8% and FDCA yield by 27.5%.

The magnitude and direction of a magnetic field created by a steady current can be calculated using the Biot-Savart law.
Consider a mobile phone battery bank as a source of steady current, which flows through the wire connected between the two. What is the magnitude of the magnetic field created by this current at a field point P?
To estimate the magnitude of the total magnetic field, we first consider a small current element of length dl, at a distance r from the field point. Now the following...

01:24Energy In A Magnetic Field
2.2K
If a magnetic field is sustained, there must be a current in a closed circuit or loop, implying some energy has been spent in creating the field. If this energy is not dissipated via the circuit's resistance, it is stored in the field.
Take an ideal inductor with zero resistance. Although it's practically impossible, assume that the coil's resistance is so small that it is practically negligible. The loss of the field's energy to dissipate thermal energy (or heat) is thus...

1.5K
An important distinction exists between the electric field induced by a changing magnetic field and the electrostatic field produced by a fixed charge distribution. Specifically, the induced electric field is nonconservative because it does not work in moving a charge over a closed path. In contrast, the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field but not the induced field. The following...

Eddy currents can produce significant drag on motion, called magnetic damping. For instance, when a metallic pendulum bob swings between the poles of a strong magnet, significant drag acts on the bob as it enters and leaves the field, quickly damping the motion.
If, however, the bob is a slotted metal plate, the magnet produces a much smaller effect. When a slotted metal plate enters the field, an emf is induced by the change in flux; however, it is less effective because the slots limit the...

In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...

Magnetic flux depends on three factors: the strength of the magnetic field, the area through which the field lines pass, and the field's orientation with respect to the surface area. If any of these quantities vary, a corresponding variation in magnetic flux occurs. If the area through which the magnetic field lines are passing changes, then the magnetic flux also changes. This change in the area can be of two types: the flux through the rectangular loop increases as it moves into the...
