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.

A new take 🤔
Format: Kindle
I’m not going to go into what this book is about — by now you e already read the synopsis and have an idea — but I will give a couple of insights. Definitely a different take on angels and their fall; I like it. This is an interesting start to a new series - YES, this does end on a cliffhanger so be prepared for that. I’m eager for the next book (and hopefully the last in this series — sometimes the author(s) will switch it up depending on how the story flows for them) in this series. I’m hoping that a certain male character redeems himself because he’s a dick that will make the meaning of mixed signals jealous lol. You ever watch that old movie — I think it’s call Mommy Dearest? — yea, let’s switch that up to daddy. That man would make a perfect husband to mommy dearest. I recommend this book because while these authors are well known for their cliffhangers, they are also well known for putting out good stories.

Liked it
Format: Kindle
I liked the worlds and the characters. The prophesy is confusing in that I would think, since all worlds ore on a path to destruction, the angels would want their world to be saved. I am sure there is more evil that will be revealed as the series proceeds. I dislike a prolonged “poor little me” trope and the main character has moved past that, thankfully, and began to show a fierce attitude as the novel progressed. The last portion of the novel had some great action. It’s worth reading, just be patient with a slow start.

Monstrously Sweet
Format: Kindle
This book packs an emotional punch, especially if you’ve experienced childhood trauma (particularly abuse and/or neglect). Alexandra creates these three strong protectors who love her and will do anything to make her feel happy and safe. She started out drawing them when she was a small child, and then transitioned to stories as she grew up. Lucien, Elwin, and Kylo look frightening in their monster forms, but it’s clear that they would never hurt Alexandra, and she has never felt afraid of them. They have very distinct personalities that we get to know better throughout the book. The love and devotion they have for Alexandra is sweet and unwavering. This is a fantastic and creative story! The world-building is wonderful - it’s a shared world with M. Sinclair, and takes place at a university for supernatural beings. The additional world-building within Alexandra’s story added even more depth and intrigue. The spicy times were 🥵 and it’s more of a medium burn, but it works with the characters and I expect that it’ll pick up quite a bit in the next books. Monsters Within has a unique way of addressing mental health issues that can come from being abused and neglected. There are some flashbacks to Alexandra’s childhood that provide some insight but they don’t go into heavy details. I absolutely adored this book and can’t wait for more!

One of us
Format: Kindle
Alexandra is literally one of us. She's just lucky her fictional men became a reality hahaha. This was a good start to what I know is going to be a great series. This was fast paced and kept me entertained. Im ready for the chaos to slow down a little bit so we can get more into the character development. There's so much happening, I feel like we hardly know anything about anyone BUT that's why this is a series so let's get to the next one!
