Molybdenum carbide energy storage

How is Molybdenum carbide synthesized?

Synthesis of the hierarchically porous molybdenum carbide The 1 mL gelatin-mediated Mo-ion matrix hydrogel was sprayed on PI (plastic, from hongxingwang plastic material Co., Ltd.) which stick on Polyethylene glycol terephthalate (PET, plastic, form Jubang Plastic Material Co., Ltd.) substrates.

How does a hydrogel convert into a Molybdenum carbide?

When ablated by the CO 2 laser, the hydrogel absorb IR energy, converting it to heat and generating high local temperature instantly. Subsequent vaporizing and reaction of the hydrogel/PI complex facilitate the conversion into molybdenum carbides/LIG with a hierarchical porous structure.

What is a porous Molybdenum carbide?

Porous molybdenum carbides are synthesized from gelatin-mediated hydrogel containing molybdenum ions, facilitated by the self-assembly of gelatin during the carbonization. This self-assembly enables the macroscopic arrangement of the lamellar hydrogel/metal-ion matrix into hierarchically layered porous structures.

Can Molybdenum carbide-based composites be used as capacitive electrodes?

This work presents a promising approach for synthesizing advanced molybdenum carbide-based composites and proposes an alternative strategy for leveraging these composites as capacitive electrodes to enhance electrochemical performance. Changlin Yang: Writing – original draft, Formal analysis, Data curation.

How much laser power is needed to convert hydrogel to Molybdenum carbide?

With a scan rate of 60 mm s −1, 7 of laser power convert the hydrogel to molybdenum carbide composite as the sample remains the hierarchical porous structure, while higher laser power below 9 results in the molybdenum carbide composite with pulverization.
