Abstract:
... The unique combination of cobalt (Co) nanoparticles (NPs) and smart polymer microgels is of great interest and has received much attention over the past decade with respect to the production of hydrogen gas and its use in removing toxic dyes from water. The responsive behavior of microgels makes cobalt nanoparticle-loaded microgels most suitable for the production of hydrogen and for the reduction ...
