Nanocatalysts include nanoscale materials having at least one nanoscale dimension of less than 100 nm. The porous nanostructured nature of the catalyst increases the surface area to volume ratio and therefore the catalytic activity of the catalyst, making it one of the attractive options for use as a catalyst.
The synthesis of stable nanoparticles with sizes between 1-100 nm is the main task of nano-chemistry. Alfa Chemistry Catalysts specializes in customizing stable nanoparticles of different sizes, compositions, dimension and shapes for catalysis.
(1) We focus on a broad range of inorganic nanomaterials, including metals, metal oxides, and ceramics—with extensive precise control over the design of nanoparticle size and technical properties. This specialization is further extended to include unique compositions such as alloys, core/shell and doped nanoparticles.
(2) We are able to synthesize nanocatalysts of different shapes, sizes, dimensions and compositions, including but not limited to zero-dimensional (nanoparticles), one-dimensional (nanowires or nanorods), two-dimensional (thin nanolayers) and three-dimensional materials.
Nanoparticles can be synthesized in a variety of ways and fall into two broad categories such as (i) top-down techniques and (ii) bottom-up techniques. Based on customer needs, our materials scientists and engineers determine the process best suited to meet performance, technical and cost requirements, and manufacture using the best synthetic route, resulting in the most economical solution.
