“…This one-step method is simple and highly reproducible; however, it has several drawbacks, namely, the generated particles are mostly spherical with the size ranging between 10 and 30 nm. To synthesize larger (or smaller, sub-10 nm) spherical particles and other shapes (rod, triangle, truncated triangle, and hexagon in 2D and polyhedral shapesdecahedron, icosahedron, and tetrahedronin 3D) additional growing steps (seed-mediated growth) and/or the usage of additives (e.g., surfactants, macromolecules) are needed. − These additives adsorbing onto the specific crystal plain inhibit the further crystal growth in this direction, thus the growth occurs along preferential crystal plains producing various nonspherical structures. Surfactants such as cetyltrimethylammonium bromide (CTAB) and cetyltrimethylammonium chloride (CTAC) adsorb on the lowest energy {111} facets and suppress their growth, which in turn directs and promotes the evolution of nanoplates. , Usually to synthesize nanoplates with a size greater than 100 nm, seed-mediated growth methods have been used. , Besides, one-step photochemical reduction methods were also proposed in the literature. , Generating both spherical nanoparticles and micrometer-sized nanoplates in a predictable size in a one-step method is challenging.…”
