Abstract
The preparation of cadmium sulfide nanoparticles that have a moderate pore size is reported. This preparation method involves a hydrothermal process that produces a precursor mixture and a following acid treatment of the precursor to get the porous material. The majority of the particles have a pore size close to 20
nm, which complements and fills in the gap between the existing cadmium sulfide materials, which usually have a pore size either less than 10
nm or are well above 100
nm.
The preparation involves a hydrothermal process and a subsequent acid treatment process, the majority of the particles have a moderate pore size, which complements and fills the gap between existing porous materials usually have a pore size either less than 10
nm or well above 100
nm.
