Annotation:

Novel nanophotocatalysts based on CdS or Cd(1-x)ZnxS nanoparticles less than 10 nm in size and mass concentration in catalyst of about 3-3,5 % deposited on outer and inner surface of halloysite nanotubes were synthesized and investigated. The obtained catalysts are efficient in reaction of hydrogen evolution from electrolyte solution under visible light irradiation. It was shown that the most ac tive catalyst is a system with Cdo,3Zno,7S nanopartilces deposited on halloysite, the hydrogen reaction rate reached 756 pmol/hgkat.
