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.

Cleans without any harsh fragrance or residue
Scent: Fragrance Free, Size: 12 Fl Oz (Pack of 1)
I got tired of other overly-scented hand soaps and decided to give this a try. It works well for a quick wash after using the toilet and when you're hands are really dirty. It rinses off easily and quickly. While it's unscented, it does have a smell - it's hard to describe, sort of like a bleach-clean scent but, it definitely does NOT smell like bleach. It just smells "clean." Since it's in the bathroom, it also gets used to clean up some other adult things. Since it isn't scented and doesn't leave any residue it's perfect for things that are in close contact with sensitive areas.

Must Use FOAMING SOAP BOTTLE for this soap & you will Love it!
Scent: Fragrance Free, Size: 64 Fl Oz (Pack of 1)
I have been using this soap refill for years and love it. I also use the scented versions when this is out of stock and they are not very strong scent. But if you prefer no fragrance, then this is a great soap. Many reviewers are complaining it is watery and thin. YES, IT IS. It is SUPPOSED to be. If you don't know how foaming soap works, you do need a couple pumps of foaming soap but you are using a fraction of the amount of soap you would use (aka WASTE) with standard soap. Have you ever seen your kid pump soap in the bathroom? Not once, or twice, but three or four times? Well, they can do that with this soap and not waste it because it's half air in each pump. It's SUPPOSED to be for foaming hand soap. Don't get fooled by your costly regular or foaming soap. Buy this and have clean hands and SAVE money! My family has very sensitive skin and nobody gets rough, red hands from this soap. No problems. HIGHLY RECOMMEND THESE FOAMING SOAP DISPENSERS FOR THIS PRODUCT: https://www.amazon.com/dp/B07PVFXSVC/ref=sbl_dpx_bath-accessories-countertop-soap-dispensers_B07Z8J57J7_0?th=1 UPDATE ON REVIEW (August 2020): I recently just ordered this item and it was delivered with new packaging. I thought it was the same product, but it seems to have additional ingredients now including alcohol. Hm. Need to look closer into this and will update when figure out what has changed. UPDATE ON INGREDIENTS (October 2020): The new formula is now showing the ingredients. It has changed. A lot. One ingredient that was removed is PHENOXYETHANOL which is GREAT they removed that! However, if they only removed that, then this would be an amazingly safe hand soap (by EWG standards it would be golden). However, it is a completely different soap with a completely different list of ingredients. I will wait until the EWG rates these ingredients before continuing to purchase this. As other reviewers have noted, it does now have "fragrance" in the ingredients - and misleadingly states "(natural)" next to the word fragrance, which means absolutely nothing in terms of what is allowed and what is not. Do your research on what the word "fragrance" means on labels and what could possibly be in your product under that ingredient. In addition it now does have alcohol in it, which some may like, however I don't think soap needs it. If you are washing, you don't need to sanitize anything. It's overkill ingredient - not needed and dries your hands out.

Cruelty free and works well!
Scent: Fragrance Free, Size: 12 Fl Oz (Pack of 1)
This soap lasts a long time. One bottle lasts one person roughly 3 weeks to a month, depending on frequency of hand washing in a day. It has a slight smell if you get near it that to me smells like a fresh clean smell. It is cruelty free and when I researched the brand, not tested on animals. It also seems like it is made out of healthy ingredients. Overall I will keep buying it.
