摘要： Palladium is a metal catalyst with excellent performance, but its application is severely restricted due to low atomic utilization and weak recovery capacity. To address these issues, we prepared a palladium nanocatalyst through a universal nanocatalysts preparation strategy. It has a particle size of less than 100 nm, possesses good superparamagnetism, and its saturation strength is 71.48 emu/g. It demonstrates outstanding catalytic properties in the reduction and decolorization of organic fuels, and the achieving conversion rates are 92 %, 99 %, and 97 % for methylene blue, rhodamine B, and methyl orange, respectively. Additionally, it can catalyze the hydrogenation dehalogenation of p-chlorophenol, with a 100 % conversion rate and selectivity. The nanocatalyst shows outstanding recyclability in the test of recyclability. Therefore, our results show that the palladium nanocatalysts have attractive characteristics of simple preparation, excellent catalytic activity and reusability. This work lays the foundation for the preparation of palladium nanocatalysts and their potential applications in areas like environmental pollution treatment.
