Synthesis, Structure Characterization and Study of a New Kind of Catalyst: A Monolith of Nickel Made by Additive Manufacturing Coated with Platinum

The monitoring of environmental contamination is an important issue to protect human health and the atmospheric environment. In this study, optical imaging mesh structures not coated with platinum was performed analyze characteristics lattices. A nickel monolith catalyst manufactured via additive manufacturing platinum, it presented characterize properties. analysis focused on process coating using hydrazine bath as a reducing agent. results showed increase in thickness baths durations 1.5 h, 2.0 h 2.5 h. strongly dependent time duration. SEM images EDX were used confirm presence catalyst. Coating layers very thin, others homogeneous over surface. When exposed for efficiency 0.06% NOx, 0.10%, CO 0.09% HC reduction.
