Product Overview

Layered double hydroxides (LDHs) are 2D hydrotalcite materials consisting of a positively charged main layer and exchangeable interlayer anions. Generally, it can be expressed as [M2+1-xM3+x(OH)2]x+[(An-)x/n]x-·mH2O (M2+ and M3+ are bivalent Ni2+, Co2+, Fe2+ and trivalent metal ions Al3+, V3+ and Cr3+, respectively, and An- is an interlayer anion (carbonate and nitrate). x is the molar ratio of M3+/(M2++M3+). For the preparation of LDHs, the main preparation methods include chemical precipitation, hydrothermal method, solvothermal method and so on. 1. The chemical precipitation method uses homogeneous chemical precursors as the substrate material, in which two or more metal ions are intricately mixed together and produce synergies to form the desired material. The main preparation process is to dissolve the bivalent and trivalent metal nitrate chemicals in deionized water with a certain molar ratio, and stir for a period of time at the appropriate temperature (generally 60 ° C), and then add the NaOH solution drop by drop and maintain the pH of the solution at about 10 ~ 11, stir for a period of time, and place it at the appropriate temperature after aging. 2. Hydrothermal method is usually used to enhance the crystallinity of layered double hydroxides. Hydrothermal method can obtain well-crystallized and evenly layered double hydroxides. The main preparation process is to mix the bivalent and trivalent metal nitrate chemicals and urea in aqueous solution to form a homogeneous solution in a certain ratio, and then add it to the reaction kettle for the corresponding time to prepare. 3. Solvothermal method is a simple and environmentally friendly method. Similar to the hydrothermal method, the difference is that hydrothermal is to mix two metals in an aqueous solution to form a homogeneous solution, while solvothermal is to mix two metals in an organic solution to form a homogeneous solution, and then put it into the reactor at a higher temperature reaction preparation.

Product Features

 

Adjustability: Suitable metal ions can be selected according to the needs of the catalyst for type or quantity modulation, so as to obtain different functions of LDHs.

Structural memory effect: LDHs can be converted into relatively stable bimetallic oxide LDOs under high temperature roasting conditions, which has good thermal stability and multi-layer pore structure, and has been widely used in the field of electrochemistry.

Strippable layer and assembly: The interaction force between LDHs laminates is relatively weak, and it is easy to be destroyed by external forces, and it is stripped into a single-layer nanosheet structure.

 

Application Fields

 

 

Electrolytic water oxygen/hydrogen evolution reaction: LDHs containing transition metal ions Fe, Co, Ni, Mn, etc., is a good OER catalyst. For example, NiFe LDHs is one of the catalysts with the best OER properties, and is also considered to be a promising non-precious metal based OER electrocatalyst. LDHs can effectively adsorb hydroxyl species, such as CoNi-LDHs has good HER activity under alkaline conditions, and its activity is much higher than Ni(OH)2 and Co(OH)2.

Biomedical field: Good biocompatibility, low toxicity, lamellae structure can accommodate biomolecules, such as the use of CoMn-LDH nanosheets loaded with photosensitizer Ce6 for photodynamic/chemokinetic synergistic therapy to inhibit tumor growth.

Ion adsorption: Due to the special layered structure of LDHs and the strong ion exchange characteristics of interlayer anions, LDHs materials are usually used for the adsorption of heavy metal ions in sewage, such as selenium (VI), arsenic (III, V) and so on.

Supercapacitors: Layered metal hydroxide is a typical Faraday pseudocapacitor material, which has a high theoretical specific capacitance and is a promising electrode material for supercapacitors. LDHs has a large specific surface area, more active sites and a short diffusion distance, which facilitates the rapid migration of ions between the nanosheet surface and the electrolyte, thus significantly improving the Coulomb efficiency of the device.

Real walnut wood. High quality.
Color: Walnut Wood, Size: Large, Color: Walnut Wood, Size: Large
This is authentic walnut wood. I was apprehensive at first. My fear was that it was pine stained to the color of walnut. I thought the wood stain would come off on my wrists and wear over time. Turns out this is a genuine chunk of walnut! Worth the $20. I laser engraved my logo onto it and it revealed that it’s 100% walnut to the core. Elegant solution. Perfectly comfortable. Way less corny than those squishy wrist rests from the 2000’s. Nice rubber gaskets on the bottom to keep it from slipping. Does not move while in typing. The exact right size for supporting your wrist on a full size Keychron keyboard. I’m using it with a P6 Ultra. But it would fit any full size Keychron keyboard.

Surprisingly comfortable and stylish wrist rest!
Color: Walnut Wood, Size: Large
This wrist rest is the perfect compliment to my desk set up. I was hesitant about buying a wood product like this, but I’ve been pleasantly surprised how comfortable and smooth it is during extended use. For the price, it feels like a premium product, and I love that it stays put with the rubber feet. The size is perfect for a full-size keyboard, with just the right thickness to keep your wrist and palms comfortable. If you’re looking for an elevated way to decorate your desk while protecting your wrist, this is a great choice.

Great wrist rest with a modern look!
Color: Walnut Wood, Size: Medium, Color: Walnut Wood, Size: Medium
This is a great looking addition to my desk. It’s a just the right length to fit my keyboard and I love the walnut coloring! It’s real wood and has nice rubber feet on the bottom to keep it from moving around. The angle is nice for my wrists and it’s easy to clean with just a damp cloth. If I ever wear this one out (which I doubt) I’d buy another!

Super comfortable - much better than memory foam wrist rests!
Color: Walnut Wood, Size: Large, Color: Walnut Wood, Size: Large
Get this wrist rest - you won't be disappointed. Had ergonomic keyboards and have tried memory foam rest in the past and this is much better. Smooth wood, perfect height and very supportive to keep wrists in neutral position when typing. Got the 17.3" and like that there's ample room to not feel squashed, but probably could have done with the medium length. Great angle for my mechanical keyboard. Love it!

What an excellent wrist rest! Except for this one thing....
Color: Walnut Wood, Size: Large
This is a solid piece of wood with great quality. Fantastic large rubber grips on the bottom (left and right sides only). Pro: I use it for editing and gaming. And though I thought the wood might be a bad choice in the long run, it turns out it's pretty nice. Not as comfortable as a gel rest but I knew what I was getting when I ordered it. I buy things for function AND aesthetics. I love how this looks. The uniqueness is really something. I got the natural one instead of the black so that the grains and lines can be easily seen. Con: Unfortunately, after almost 2 months, the wood has warped some. Not enough to effect my typing but, enough that I notice it. The warp is the kind where the opposite angled corners go up and down. While the other 2 corners are fine. In my case, the top left and bottom right, when pressed independently, rock the wrist rest. The top right and bottom left stay grounded. This is why I took a star off. Because there's no way this should be happening. So, looks and quality are up there. The rubber grips are solid. Why it's warping is puzzling to me. NO liquid wasted on it. Or, extreme temperature changes have happened. I've made sure the rubber grips. And that the surface the rest sits on (a glass mouse scrolling top by Superglide) is clean. Yet, I get this slight rocking. It bugs me this all happened right after the return window closed. I would've simply exchanged it. I love it too much. I mean, this is, again, a SOLID piece of wood. Maybe this won't happen for everyone. I mean, it's wood. Eh I would still recommended this regardless.
