The basic characterization techniques of catalysts are powerful tools for gaining a deeper understanding of their physical, chemical, and structural properties. Through comprehensive application, the catalytic reaction mechanism can be revealed, providing a theoretical basis for the design and development of high-performance catalysts. With the advancement of technology, this technology continues to innovate and develop towards higher resolution, more accurate quantification, and better simulation of real reaction conditions.

A dispersant is a chemical substance used to disperse nanoparticles in solution or solid. Its basic principle is to interact with the surface of nanoparticles, change surface characteristics, reduce the attraction between particles, and achieve the dispersion of nanoparticles.

The gold price has hit a high of 720 RMB per gram, as international gold prices continue to rise. This surge in gold price has led to increased demand for high-quality gold products, such as nanoscale gold powder. SAT NANO, a leading provider of nanomaterial products, offers the perfect solution with its nanoscale gold powder, which is 20-30 nanometers in size and has a purity of 99.99%.

​Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.

Hydroxyl groups (- OH) can exhibit acidity or alkalinity on the surface of metal oxides in the form of proton reception or supply. By adjusting the quantity and distribution of hydroxyl groups, precise control of surface acidity and alkalinity can be achieved, thereby affecting the activation pathway and selectivity of catalytic reactions.
