Title: Three-Dimensional Printed MoS ₂ /Graphene Aerogel Electrodes for Hydrogen Evolution Reactions

Abstract

In this work, we demonstrate the use of direct ink writing (DIW) technology to create 3D catalytic electrodes for electrochemical applications. Hybrid MoS₂/graphene aerogels are made by mixing commercially available MoS₂ and graphene oxide powders into a thixotropic, high concentration, viscous ink. A porous 3D structure of 2D graphene sheets and MoS₂ particles was created after post treatment by freeze-drying and reducing graphene oxide through annealing. The composition and morphology of the samples were fully characterized through XPS, BET, and SEM/EDS. The resulting 3D printed MoS₂/graphene aerogel electrodes had a remarkable electrochemically active surface area (>1700 cm²) and were able to achieve currents over 100 mA in acidic media. Notably, the catalytic activity of the MoS₂/graphene aerogel electrodes was maintained with minimal loss in surface area compared to the non-3D printed electrodes, suggesting that DIW can be a viable method of producing durable electrodes with a high surface area for water splitting. Furthermore, this demonstrates that 3D printing a MoS₂/graphene 3D porous network directly using our approach not only improves electrolyte dispersion and facilitates catalyst utilization but also provides multidimensional electron transport channels for improving electronic conductivity.

Supercapacitors Based on Three-Dimensional Hierarchical Graphene Aerogels with Periodic Macropores

Journal Article Zhu, Cheng ; Liu, Tianyu ; Qian, Fang ; ... - Nano Letters

Graphene is an atomically thin, two-dimensional (2D) carbon material that offers a unique combination of low density, exceptional mechanical properties, thermal stability, large surface area, and excellent electrical conductivity. Recent progress has resulted in macro-assemblies of graphene, such as bulk graphene aerogels for a variety of applications. However, these three-dimensional (3D) graphenes exhibit physicochemical property attenuation compared to their 2D building blocks because of one-fold composition and tortuous, stochastic porous networks. These limitations can be offset by developing a graphene composite material with an engineered porous architecture.

3D Printed Carbon Aerogels for Polymer-Electrolyte Fuel Cells

Journal Article Santamaria, Anthony D. ; Chandrasekaran, Swetha ; Philbrick, Oliver ; ... - ECS Transactions

Carbon aerogels (CA) are known for ultra-low density, very high surface area, fine porous structure, and excellent electrical conductivity. Recent advances in high resolution 3D printing at LLNL enable the manufacturing of complex structured CA electrodes which have been demonstrated in electrolysis, flow battery, and supercapacitor applications. Polymer-electrolyte fuel cells (PEFC) may be an excellent candidate for these materials/methods as designers seek to optimize membrane-electrode assemblies to achieve higher efficiencies. A major challenge to PEFC design is two-phase flow due to water production which causes pore flooding and leads to cell instability and degradation. To mitigate these effects, groups havemore »« less

3D-Printed Graded Electrode with Ultrahigh MnO₂ Loading for Non-Aqueous Electrochemical Energy Storage

Journal Article Lin, Dun ; Chandrasekaran, Swetha ; Forien, Jean‐Baptiste ; ... - Advanced Energy Materials

Abstract Electrolytic manganese dioxide is one of the promising cathode candidates for electrochemical energy storage devices due to its high redox capacity and ease of synthesis. Yet, high‐loading MnO ₂ often suffers from sluggish reaction kinetics, especially in non‐aqueous electrolytes. The non‐uniform deposition of MnO ₂ on a porous current collectors also makes it difficult to fully utilize the active materials at high mass loading. Here, a 3D printed graded graphene aerogel (3D GA) that contains sparsely separated exterior ligaments is developed to create large open channels for mass transport as well as densely arranged interior ligaments providing large ion‐accessiblemore »« less

Efficient 3D Printed Pseudocapacitive Electrodes with Ultrahigh MnO₂ Loading

Journal Article Yao, Bin ; Chandrasekaran, Swetha ; Zhang, Jing ; ... - Joule

Retaining sound electrochemical performance of electrodes at high mass loading holds critical importance to energy storage. Pseudocapacitive materials such as manganese oxide (MnO₂) deposited on current collectors have achieved outstanding gravimetric capacitances, sometimes even close to their theoretical values. However, this is only achievable with very small mass loading of active material typically less than 1 mg cm^-2. Increasing mass loading often leads to drastic decay of capacitive performance due to sluggish ion diffusion in bulk material. In this work, we demonstrate a 3D printed graphene aerogel electrode with MnO₂ loading of 182.2 mg cm^-2, which achieves a record-high arealmore »« less

System and method for 3D printing of aerogels

Patent Worsley, Marcus A. ; Duoss, Eric ; Kuntz, Joshua ; ...

A method of forming an aerogel. The method may involve providing a graphene oxide powder and mixing the graphene oxide powder with a solution to form an ink. A 3D printing technique may be used to write the ink into a catalytic solution that is contained in a fluid containment member to form a wet part. The wet part may then be cured in a sealed container for a predetermined period of time at a predetermined temperature. The cured wet part may then be dried to form a finished aerogel part.
