Project Description

This project will investigate an innovative synthesis route for bulk scale synthesis of high purity and size controlled production of nanosized particles, such as silver and gold through a different chemical process than is currently utilized, thus leading to useful materials with a strong scientific and economic interest.

Key findings

The major HyperActiv Project results are listed below:
1. The HyperActiv Project research goals were achieved. The whole range of noble metals (silver, gold, platinum, palladium and ruthenium) nanoparticles were synthesized under hyperstoichiometry conditions via silicon-hydride chemistry. Various solid substrates were used for silicone-hydride modification and therefore for the noble nanoparticles attachment. The synthetic approach was proven for successful scale-up from nano to macro range with extended range of noble metal nanoparticles loading. The major research novelty of the Project is in the synthetic procedure in general (one-pot, environmentally clean, redox synthesis) as well as in the extended list of noble metal nanoparticles formed and selection of substrates utilized.
2. Site survey at the Pavlodar (mercury contaminated lake-reservoir Bylkyldak, RK) and nearby lakes and wetlands was performed. A recorded track of environmental mercury contaminated samples of water, soil and sediment (GPS controlled, filmed and photographed), was collected.
3. Training needs for early-stage researchers was followed by the following training: communications (knowledge transfer), internships (ICP in Almaty, EKSTU in Ust’ Kamenogorsk and TU in Japan), field trip practice training (contaminated site in Pavlodar), and a knowledge dissemination (per-reviewed articles, project and conference paper writing and presentation). Beneficiaries were early-stage researchers (undergraduate and graduate students) at the Nazarbayev University.
4. A strong and sustainable research network contributes significantly to nanoparticle research and to mercury decontamination was formed during the HyperActive Project lifespan
